The 3 DSLR Lenses You Need (and 2 More You’ll Crave)

This goes out to people who bought or want an entry-level DSLR, and wonder what’s the deal with interchangeable lenses. You really gonna buy that extra glass? It’s a beginner’s guide to growing as a photographer, preferably without going broke.

It doesn’t matter what brand of camera you bought—if it’s an entry-level DSLR, it was offered to you with an 18-55mm kit lens. I hope you took them up on that offer because no matter what you bought, that kit lens comes cheap, and is well worth it. Yes, of the five lenses covered here, that kit lens is numero uno.

KIT LENS
Like most bundle pricing, it’s cheaper than buying the camera body and lens separately, and most experts agree that an 18-55mm is actually the perfect lens for most immediate photographic needs, with both a decent wide angle plus the ability to zoom in on far away objects. In fact, if you take a look at the four shots below—all taken by me with kit lenses on basic DSLRs—you can see a foreshadowing of the four other lenses in this briefing—telephoto, wide-angle, portrait and macro:

But if you read Gizmodo enough, you know that we’ve made the case that lenses, and not the cameras themselves, account most for great pictures. Photography is an optics game first and foremost, and there’s a point at which that kit lens can’t achieve shots that your heart and soul tell you are achievable. There’s nothing wrong with your camera—seriously, there’s nothing wrong with it. You just need to get some more lenses.

In order to run this story I called some experts at Canon, Nikon and Sigma, which makes discounted lenses for most DSLRs. I could have called experts at [insert your favorite non-Canon or Nikon camera brand here] but early on, the advice was consistent and clear: Anyone who is really taking an interest in their camera should invest in a telephoto zoom next, followed by a fast “normal” lens, which you might call a portrait lens.

LENS LABELING
In the interest of speed, I can’t talk about lens anatomy, but there are some key attributes you need to know to read all lens retail listings: focal length and aperture.

In most cases, the lens categories here differ by the focal length, that is, how close a subject appears, indicated in millimeters. The human-eye equivalent is between 30mm and 50mm. A telephoto lens, which gets up close to things that are far away, can be as long as 500mm. A wide-angle lens, which makes close-up objects appear farther away, can be 10mm—still less if you want the bulbous fisheye look. A “zoom” lens simply means that it has a variable focal length—for instance, your kit lens, which can hit any length from 18mm to 55mm.

Because entry-level cameras have smaller (APS-C) sensors than professional APS) full-frame 35mm cameras, everybody makes two sets of lenses. Typically all lenses work on beginner cameras, but beginner lenses don’t work on pro cameras. If you stick with beginner lenses (denoted Nikon DX, Canon EF-S, Sony DT, Pentax DA, Sigma DC and Tamron Di II), you won’t have to stress, but if you want to buy a pro lens, or have some lying around, bear in mind that you need to multiply the focal length by 1.5 or so to get the equivalent focal length for your camera. A 50mm pro lens is really a 75mm lens on your beginner’s model. Why am I telling you this? Because there are new and used pro-level lenses out there for really good prices.

In one case below, what sets the lens apart is its large aperture. The aperture is the hole that lets in the light, and it’s measured by the f-stop. A wider aperture means more light comes in, and you have a better chance of getting nice shots indoors, in dimmer settings. A narrower aperture lets in less light. The trade-off is that a wide aperture can’t focus on as many things that are at different distances—it is said to have a “shallow depth of field.” Your main subject is clear, but the background is blurry—artistic in many cases, annoying in some. When you narrow the aperture, you can crisply resolve more elements, but only if there’s enough light. The wide aperture of a “fast” lens can always be narrowed, but there’s no way for a “slow” lens with a narrower aperture to bring in more light.

As if that wasn’t tricky, check this out: The f-stop is a fraction, and the number you refer to is on the bottom, so if it’s low (f/1.4), the aperture is wide, and if it’s high (f/6.0), the aperture is narrow. Got it? Zoom lenses at beginner prices tend to have variable f-stops, apertures that get narrower, and in need of more light, as you zoom in.

TELEPHOTO ZOOM
Lenses in many ways are about reach, about bringing faraway subjects closer to your camera’s sensor. “The low-end customer, who may take out their DSLR only occasionally, says, ‘I want to shoot a picture of the moon, or animals at the zoo, or kids playing soccer,'” says Dave Metz, a lens specialist at Sigma. Even when that kit lens is cranked to the max, it’s only giving you a 55mm focal length, which is why most DSLR makers have a very well-priced 55-200mm lens waiting at the ready. Prices range from $120 to $250, and it’s usually the easiest purchase to make.

Another telephoto zoom lens you’ll see is the 18-200mm, which can cost anywhere from $350 to $600. That’s a hefty premium to pay just so you don’t have to schlep around two lenses, and generally speaking, the broader the focal length range, the more corners are being cut in performance. That lens is a pass.

If you are feeling particularly far out, both Metz and Nikon’s camera marketing guru Steve Heiner suggest a 70-300mm lens. Sigma’s model sells for under $200, Nikon’s most recent model, with built-in image stabilizing, is just over $500, and there are 70-300mm lenses for everyone else ranging from $130 to $850, all with variable f-stops of either f/4.0-5.6 or f/4.5-5.6. Better yet, these lenses are spec’d for pro-grade full-frame cameras, so they’re exceptionally zoomy on your beginner’s camera, more like 105-450mm. Hey, don’t think about it too much, just enjoy it.

NORMAL (AKA PORTRAIT)
As much traction as you’ll get from a zoom lens, it doesn’t really teach you much, except maybe how to compose without cropping. I personally learned a hell of a lot more about photography when I started playing with f/1.8 50mm lenses. This is called a “normal” lens because, says Heiner, “It was all you could get on a camera in the ’50s and ’60s.” In fact, he jokes that even though younger people are snapping up this relatively cheap lens ($100 to $150), he and his ilk “couldn’t wait to get away from it” when zoom lenses started hitting the market.

What does it do? As a “fast” lens, it can shoot really well in low light. Keep the aperture wide, get up in your subject’s grill, and start clicking. You’ll see parts of their face sharply resolved while other parts are softly blurred. Tighten the aperture a tad, and your subject’s whole head is clear while the backdrop is soft and peaceful, even if it’s a Manhattan street corner at rush hour. What doesn’t it do? It doesn’t zoom, and because it’s usually rated for pro cameras, it’s about the equivalent of 75mm on an entry-level DSLR—which is roughly the preferred focal length for portrait shooting—so you often have to step back to get a decent shot.

Alternatives to the cheap f/1.8 lens are an even faster one, f/1.4 ($300 to $500), or a 30mm or 35mm that gives entry-level cameras more of a “normal”—what your eye can see—perspective.

At this point, in addition to the original cost of your camera, you’ve spent less than $500, and you’ve added immeasurable functionality and artistic wiggle room. You can stop here, and you won’t be judged. But, if you like, I can tell you about two more lenses that might rock your casbah.

ULTRA-WIDE ANGLE ZOOM
That kit lens brings you down to 18mm, which is enough for you to stand in a corner of a room and shoot pretty much anything going on in that room. But what if you’re not in the corner? The same twist of fate that makes pro-level telephoto lenses even more zoomy on your entry-level DSLR makes wide angles trickier—or at least more expensive—to attain.

Why is this? Film is flat, so light can come in at any angle, and the film will mostly record it. But camera sensor pixels are concave, and don’t do well with light coming in from the side. Think of the pixels as little water glasses, says Sigma’s Dave Metz. “You can fill them up with water by pouring it in from above, but try shooting it in from the side with a garden hose, and it’s going to go all over the place.” A telephoto by definition is pulling in light from directly in front of it, whereas a wide angle by definition is bringing in light from the sides, too. Hence the trouble, and the added expense.

But if you have the means, it’s the consensus of my experts that you should pick yourself up an ultra-wide-angle zoom lens (10-24mm, 10-22mm or 10-20mm). Just be very careful that it’s one built specifically for entry-level DSLRs, with the arcane designations I mentioned in the “Lens Labeling” section. Discounted on Amazon, Nikon’s is selling for $809 while Canon’s is around $730. Tamron and Sigma make them for Canon and Nikon for just under $500.

And the aesthetic pay off? As Metz tells it, “I am sure you’ve seen a beautiful mountain scene; in the foreground there’s beautiful little flowers. Because they’re so close, they appear out of perspective. You effectively enlarge the flowers.” It’s also, as he points out, the best way to make sure that all the uncles and aunts are included in the family portrait you take at the Christmas dinner table.

MACRO
The final stop on our survey of lens-topia is the macro—or big hairy bug—lens. “When I try to show people about macro photography, they say ‘What is that?'” says Lisette Ranga, a Canon camera marketing specialist, “but when they look through the viewfinder, and see how close you can get, they get it.” While I don’t understand why people like taking pictures of bugs and flowers so much, I am a victim of the chronic urge to do so. Though some are 50mm or thereabouts, many macros are telephoto lenses. The ideal, it seems, is to shoot stuff up close that you wouldn’t even want to get near—he who snaps the most snakes and scorpions wins.

So what do you look for? Typically, macro lenses have a fixed aperture of f/2.8 (sometimes f/2.5). Sigma has five lenses, ranging from 50mm ($300) to 180mm ($900), all fixed, plus a few zooms such as the one I personally want to try out, the 24-70mm ($570, compared to well over $1,000 for the equivalent Canon or Nikon). What’s cool is that when you’re not photographing scorpions (or stamps or coins or documents), you can use these for portraits and other “normal” shooting, but with such sharp resolve that some even recommend a bit of digital softening.

So you see, adding those final two lenses more than doubles your investment, and for a diminished payoff. That’s what you would buy next, but for most of you, it’s not what you should be buying.

IMAGE STABILIZATION, LENS MOUNTS AND YOUR DADDY’S LENS COLLECTION
Though some readers probably gave up on this story a long time ago, I have made every attempt to keep it clear and moving. In doing so, I skipped over lots of hot topics, including image stabilization and lens compatibility.

Canon and Nikon currently promote the hell out of image stabilizing lenses, in large part because their cameras do not have in-camera image stabilization like Sony, Pentax and Olympus. While image stabilization does tend to matter, its location doesn’t seem to matter as much. The consensus on the internet is that it’s a drag to have to buy IS in lenses over and over, and from what I’ve seen, there is a clear added cost when buying lenses a la carte. Nevertheless, there’s a premium for buying Nikon and Canon because they are consistently the best reviewed and the biggest sellers, so there’s no right or wrong. It’s just something to look for when buying lenses, and to discuss with your favorite camera nerds.

The main reason Canon and Nikon don’t have IS in their cameras is that the camera technologies pre-date the digital revolution, and it was harder to do with film. The flipside is this: Older film-based lenses from Canon and Nikon work on newer Canon and Nikon digital cameras. For Canon, it’s the EF standard, which dates back to 1987. If the lens says EF on it, it will work. If it says EF-S, it was specifically made for entry-level DSLRs, and won’t work on pricier pro models. If you put an EF lens on a camera that typically takes EF-S lenses, remember to multiply by 1.6 to figure out the real focal length.

For Nikon, it’s a tad weirder: Any F-mount lens dating back to 1959 will fit on the thing, but only the lenses labeled AF-S will definitely work with D40/D60/D90/D3000/D5000 class of entry-level DSLRs. If the lens doesn’t say “DX” on it, multiply the focal length by 1.5 to see what it really is. If your dad hands you a bag of Nikon lenses, accept them graciously, and try them all out, but be ready for weird results, or at the very least, a sudden lack of autofocus and auto metering.

LENS QUALITY
I want to leave you with one final bone of contention—the quality of the lenses. I recognize that I have made many suggestions that seem like go-out-and-buy-’em recommendations. I do think that shopping for new lenses on a tight budget is a good way to expand as a photographer, but this is not a “buyer’s guide.”

Many photography enthusiasts believe buying a cheap lens to attach to your camera would be like buying a used prophylactic to… well, I’ll spare you the imagery. But the point is, there is surely a reason why third-party ultra-wide-angle zoom lenses cost half as much as big name versions, just as there is surely a reason why Canon’s 50mm f/1.4 costs nearly four times as much as its 50mm f/1.8. There are real differences in lenses, and I’m happy to invite you to discuss them below.

Sprint, Samsung Launch Biodegradable Phone Made of Corn

samsung-reclaimEco-friendly phones are all the rage among handset makers now.  Samsung became the third phone manufacturer, after Motorola and Sony Ericsson, to offer a device made from biodegradable materials.

The new Samsung phone, called Reclaim, is a slider-style phone with a QWERTY keyboard and a 2 megapixel camera.  The phone will be available on Sprint’s wireless network starting Aug. 16 for about $50, after rebates, and with a two-year contract.

Green phones have taken off this year. At the Consumer Electronics Show in January, Motorola showed its W233 Renew handset whose plastic casing is made of recycled water bottles.  In June, Sony Ericsson announced two new eco-friendly phones.

Reclaim follows that trend. The phone is made from 80 percent recyclable materials, said Samsung. A bio-plastic material made from corn makes up about 40 percent of the phone’s outer casing. The device is also free of polyvinyl chloride (PVC) and nearly free of brominated flame retardants (BFR) — materials that organizations such as Greenpeace have been actively lobbying to eliminate from gadgets.

The packaging for the phone and the phone tray inside the box are made from 70 percent recycled materials, claims Samsung. Images and text on the box as well as the phone warranty information are printed with soy-based ink. And there will be no thick paper user manual offered with the phone. Reclaim’s charger is also Energy Star approved to meet efficiency standards.

Sprint said it has established a set of environmental design criteria for future devices and accessories.

Inside Sonys New Image Cubed Cameras

Sony schematic image.jpgThis morning Sony launched two new cameras, the Cyber-shot DSC-WX1 and the Cyber-shot DSC-WX1, along with a nifty robotic accessory that can take pictures of you and your guests at a party.

The cameras are part of a marketing concept Sony calls Imageᶾ (pronounced “image cubed”). This marketing speak was first introduced to the company’s camera line at the Las Vegas launch of a 20x super-zoom Sony Cyber-shot DSC-HX1.
Cameras in the Imageᶾ family have three ingredients: a fast BIONZ (pronounced “bee-onz”) image processor, a redesigned Exmor R CMOS image sensor, and a premium Carl Zeiss or G Series lens. These additions enable the cameras to produce high-quality images and offer software-driven features such as quickly created panoramic images, advanced software noise reduction, and high-definition video capture. (More info on these technologies here).
For a glimpse at the inside schematics of the two new cameras, check after the jump.

Kinpo VIA Nano-powered netbook rocks the 3G (but only in China)

We’re starting to see more companies throw VIA Nano processors into the netbook mix as of late, and now it looks like Kinpo (last seen with an Android-sporting tablet) is getting in on the action with the N03. This guy has an 11.6-inch (1366 x 768) display, comes with either a 1.2GHz or 1.3GHz VIA Nano processor, and sports integrated TD-SCDMA 3G (the China-specific 3G standard), HSDPA/HSUPA, W-CDMA, and EVDO. Also on hand are WiFi, options for either SSD or HDD storage, up to 2GB memory, a 1.3 megapixel webcam, and your choice of either Windows XP or Vista Home Basic. The company is “boasting” a 3 hour battery life, which is a shame — with all that connectivity, this device is otherwise well suited for situations where plugging in isn’t really an option. No word on price or release date, but we’ll keep you posted. [Warning: PDF read link]

Touchable Holography uses Wiimotes to add touch to holograms

Researchers from The University of Tokyo have demoed a touchable hologram at Siggraph 2009. The project, called Touchable Holography, involves the use of Wiimotes placed above the display to track hand motion, and an airborne ultrasound tactile display created in the university’s lab to create the sensation of touch. The result is a holographic image that produces tactile feedback without any actual touching, and without degrading the image itself. Check out the video after the break for a fuller, more stunning explanation.

[Thanks, Adam]

Summermodo: Gadgets Go Outside


Unlike Silicon Valley’s, San Francisco’s summer is fake, cold and foggy. Every year that goes by away from my beloved New Jersey, I forget what the season is really about: Fun away from the PC. And sweaty pants.

For most of my adult life, I lived up to the modern stereotype of a geek by staying connected and staying inside and equally pale year round. And I regret it. I don’t know why we live like this, when the gadgets are inherently meant to be used outside, capturing photos and videos of the best memories not in front of our Xboxes, and wireless speeds and smartphones are so good at keeping us in touch with work and loved ones while we’re traveling. There’s no excuse, if you love life.

Except, as I said, my excuse has been San Francisco. Because of the consistent climate, I just always tend to forget about any seasonal change. June hits and we have all these Apple keynotes and whatnot, and then July starts and finishes within something like, oh, 30 days and August will inevitably do the same. Then September happens, which is the spiritual death of Summer for everyone, student or not. I thought to myself, here you go again, taking things for granted. So I sought out the sun. Lisa plotted a vacation, to Kauai and Oahu. Hawaii was personal time. I was doing nothing but camping on the beach, jumping into lava formed tide pools and did not check my email or phone for 4 days. The world did not end. I surfed a little and visited friends like Philippe resting after his big race. I brought minimal technology along the way. I can’t say it was good. Apparently, when I ditch the internet, I start binge eating to replace the stimulation of twitter and blogs and email. Once, I ate three meals in a row with major ingredients being SPAM (the meat) before 4pm one day. There was a second, non SPAM dinner after that. And two working days later, 4400 new messages. Christ alive.






I got back last Wednesday and immediately took off with some Gizmodo writers and friends to REAL Watersports at Cape Hatteras, North Carolina, to learn how to kiteboard, surf, drink a lot of sponsored beers (Heineken Light, thanks for the trip) and ultimately, test beach and water gadgets. And in the proper context of being outside, we realized that half of the gadgets we thought were cool were dumb, and half of the ones we thought were useless were totally impressive. You can’t really test out waterproof cameras without spending time with them on the beach or in the ocean. Cases get beat up, lenses get smudged with grime and cam housings cause ridiculous amounts of glare out of the H2O. Nor can you do the same with Jetskis or metal detecting sandals. It’s all more subtle than that, but I’ll save it all for the reviews, which will come.

The reason the trip was sponsored is that we wanted to get some help from our friends. We invited Joel Johnson of Gizmodo/BoingBoingGadgets fame, John Mahoney from Giz and Pop Sci, and Seth Porges from Popular Mechanics, and invited them to bring as much gear as they could haul down. And Cape Hatteras was an incredible place. Basically, the area is a mecca for kiteboarding and surfing, with the outer banks being exposed to a shallow body of water to the west, almost 30 miles wide in some parts, calm but windy for kiteboarding, and the biggest surf breaks on the Atlantic coast on the other side of the island, which was walking distance away. When it came time to kiteboard, we got slaughtered. It’s basically like wakeboarding on a boat while remote controlling a kite that’s pulling you. And really, we’re not the most athletic crowd, so that didn’t help much. Also, it rained a whole bunch. One day, we only got into the water by borrowing some demo skimboards and surfboards from REAL and heading towards the Atlantic. The current was strong, but it was just so satisfying to finally swim in the Atlantic, after all these years. It’s a little darker, but because of the gulfstream, a lot warmer. Can’t say I missed my wetsuit all that much.

It was muggy, and the summer showers as relentless as the mosquitoes, things that I wouldn’t have to deal with in the monotone climate of SF, but nothing compares to the lift of spirits I get spending time with the people who write for this site, eating bbq and testing tech. We all work remotely and generally only see each other when there’s a, like, super-serious liveblog or CES show to cover. And I remembered not only how much I love this feeling of…well, summer, but how much different tech is in the context of the heat, the moisture and really the distraction of the real world.

‘Till school starts we’ll be running more stories about tech and summer. Sometimes involving the ocean sometimes the beach, sometimes just the most tangential of connections. It’s already August, but I’ll be satisfied if we can celebrate what’s left of the most glorious time of the year and what it means to all of the tech nerds here.

Summermodo is a chance for Giz to get outside and test our gear where it belongs.

Raytheon sells its first ‘pain ray,’ and the less lethal arms race begins

As you are no doubt aware, one of the perks of being in the corporate security field is that you get to try out things that would come across as, well, unseemly if put in the hands of the government. While there’s been some controversy over the possible use of Raytheon’s 10,000 pound “portable” Silent Guardian by the military, it appears that at least one private customer has no such qualms. We’re not sure exactly who placed the order — news of an “Impending Direct Commercial Sale” was just one bullet point of many at Raytheon’s recent presentation at a NATO workshop on anti-pirate technologies. The company itself is being mum on the subject, saying that it would be “premature” to name names at the present time, but rest assured — this is only the beginning. As soon as these things are small enough to fit in your briefcase or glove compartment, every nut in your neighborhood will want one. In the mean time, looks like you’re stuck with the Taser.

Laptop Mag’s tech support showdown strikes once again

Laptop Magazine‘s once again done us all a really good turn by running a pretty exhaustive — yet totally reasonable — test of the tech support for ten popular companies that produce laptops. Essentially, they placed two call to each outfit’s support — one during peak, one during off-peak hours, and asked them some really basic questions such as “How can I make changes to my notebook’s power settings?” Then, they tried to find answers to the same questions via the company’s various web-based resources. So, what’s the skinny? Well, only Apple got an “A,” while Acer, Dell and HP hold the bottom spots with a “C-” score, while everybody else falls somewhere in the middle. The report, is, however, a really fascinating read with far more information than mere letter grades, so please — click the read link to read the entire, epic tome.
