Slow-Motion Video of Lens Aperture Blades in Action

If this infernal machine were bigger, it could be used to torture the inhabitants of hell. Forever

If you’re not subscribed to Preston Scott’s Camera Technica blog, you should be, and here’s why: This is a video shot by Scott showing the aperture blades inside an SLR lens, opening and closing in slow motion. The lens is a Canon 18-55 zoom, which has been “carefully excavated” to reveal the aperture mechanism. The video is shot at 120 frames per second.

It’s a wonder that it even works, let alone that it works time after time without those blades having a nasty crash. What I love most about the video, though, is the sound. The relentless mechanical grind, repeating over and over, is like something from Fritz Lang’s Metropolis, both menacing and coldly indifferent at the same time. Hypnotic.

Video: Lasers Show Up Wobbly Camera Mirrors

You do NOT have steady hands, and the laser proves it. Photo Preston Scott

You know when you read that you should use a tripod to get the sharpest possible photographs, especially in low light, and you’re all like “Whatever,” and “I have steady hands, dude.”

Well, take a look at this video, which shows just how much you SLR can shake, even when it is on a tripod. Preston Scott at Camera Technica secured a laser pointer to the hotshoe of his Canon 7D and made this video to show you just how wobbly things can get.

The clip shows the laser as it shines onto a wall 20 feet away from the camera. The 7D was locked down on a tripod and took three shots. The first is made by pressing the shutter release carefully with a finger. The resulting vibrations, caused by both the finger and the mirror slapping up inside the body, make the laser careen wildly.

The second shot was taken with a remote release but with the mirror still flapping free. It isn’t much better than the first.

Lastly, the shutter was fired remotely with the mirror locked up (a function of higher-end SLRs).

It’s amazing how much vibration is caused by the internal mechanics of the camera, and when your fat fingers are factored in, it’s surprising you can manage to take a sharp photo. Clearly, at slow shutter speeds, it is worth locking up that mirror, using a tripod and a remote release.

Alternatives are to use a mirrorless or a rangefinder camera, which eliminates mirror slap entirely, or to buy a Nikon SLR, which will have considerably smaller mirror bounce (oh no he didn’t).

HipstaCase Wraps iPhone in Retro-Tastic Coating

The HipstaCase makes your iPhone as retro on the outside as it is on the inside

This is the iPhone case you have been looking for. It is the official Hipstamatic case, and it is called, of course, the HipstaCase.

Hipstamatic is an iPhone app which turns your pristine digital shots into something resembling the results from a kids’ toy plastic camera from the 1970s. Low contrast, color casts and light leaks are its main “features”, and we love them. Now you can complete the look and make your iPhone as retro on the outside as it is on the inside.

The one-piece snap-on case makes your phone (or iPod Touch — there are two versions) look like a retro camera, but it also has some extras, or “swankeries.” First is the wrist lanyard, which is included in the kit. Second is a tripod mount. This is an extra bracket which slides into the bottom of the “lens” and lets you screw it to a tripod bush.

It isn’t cheap, at $40, but I think the Gadget Lab crew has finally found the perfect birthday gift for the preposterously handsome Wired.com photographer Jon Snyder. This is a man so addicted to Instagram (the amazing iPhone Lomo-Twitter app) that the app’s icon sits alone on his iPhone’s homepage. Happy Birthday, Jon! (whenever it is).

Pinwide: Wide-Angle Pinhole Lens for Micro Four Thirds Cameras

A photo taken using the Pinwide on an Olympus EP1

The Pinwide is a plastic pinhole for Micro Four Thirds cameras. The little injection-molded cap bayonets onto the camera like any other lens, only instead of focusing the image using glass, it has a precision-etched, circular pinhole at its center.

You could make your own, but at just $40 it’s a deal even for DIY types. It looks like fun to use, too. The high-quality pinhole gives some fairly sharp images, and because it has an aperture of around ƒ96-ƒ128, everything from front to back in your image will be in focus.

The Pinwide has another feature that your homemade version won’t: it’s wide-angle. By dishing the disk and putting the hole back inside the body, the Pinwide achieves a focal length of 22mm, or 44mm on the Micro Four Thirds bodies. This, along with the infinite depth-of-field, makes for some interesting photo opportunities. Also: Pinhole video.

Sounds good, right? In fact, I convinced myself and just ordered one. I’ll let you know how it works out.

Stolen Camera Finder Finds Stolen Cameras

Drag a photo onto the box and it will search for other pictures with your camera’s serial number

If you lose your phone or your computer, there’s a fair chance you’ll get it back if you’re using some kind of tracking software. As we have seen before, Apple’s Find my iPhone service has rescued more than one lost phone. But what about your other gadgets?

If your camera is stolen, you now have at least a chance of finding it thanks to the Stolen Camera Finder by Matt Burns. It works by searching the web for photos bearing the serial number of your camera. This number is embedded in the EXIF data of every photograph you take.

Using the tool is easy. Just visit the site and drag a photo from your camera onto the waiting box. The tool searches its database for your camera and if it finds it, you can then go see the pictures. This may — hopefully — give you some clues as to where it is now. You’ll need to use a JPG image (RAW doesn’t work) and some cameras don’t write their serial number into the metadata.

The data comes from Flickr, and also from data crawled from the web. Matt has also written a browser extension for Google Chrome which will check the serial number of photos on every page you visit and add it to the database.

I tried the tool with a photo from my camera, and nothing showed up. I have a ton of photos online, on both on Flickr and here at Wired.com, so I was expecting something. I guess that the service will increase in value as time passes and the database grows. Still, the service is free, and if nothing else it lets you view a whole lot of information about your photos in the drop-down list.

Nikon’s D5100 impresses, captures children’s birthday parties with incredible clarity

Nikon D5100

We’re not the only site to put Nikon’s new mid-range DSLR through its paces. Plenty of others have taken the D5100 for a spin and we thought you might like to know: they’re all pretty impressed. The new 1080p30 video mode was much appreciated as was the larger, higher resolution swivel screen around back. The biggest props generally went to the improved high-ISO performance (which was already quite respectable on the D5000 it’s replacing) and the boost in autofocus speed, especially when using the LCD as a view finder in Live View mode. Oddly, the built-in effects also garnered a lot of attention. The Miniature Effect (a tilt-shift simulator) and Selective Color mode impressed reviewers the most with their surprising level of sophistication for in-camera processing. All of the effects can also be used when shooting video, so you can make your HD footage look like black and white 8mm by turning on Night Vision. Criticisms were relatively minor and applicable to most mid- and entry-level DSLRs — primarily that the body is plasticy and there is a slight lag in focus and shutter performance. The D5100 is an obvious upgrade over the D5000 and more than holds its own against its competitors, but if you want to dig deeper check out our review and the ones below.

Nikon D5100 impressions, head-to-head with D7000

Nikon has stirred up the camera crowds once again with its newly released D5100, filling the industry with the buzz of a new high-resolution articulating screen. In terms of consumer DSLR options, the D5100 has taken on the role of the mid-range model in Nikon’s product line between the D3100 and the D7000 and we think it assumes the part rather nicely. In terms of price, the D5100 fits right in as well, fetching an MSRP of $900 (vs. $700 and $1600, respectively for the two aforementioned camera kits). Of course, the D7000 lands you the better 18-105 f/3.5-5.6G ED AF-S VR lens, a larger and brighter viewfinder, built-in focus motor, weather-proof sealing, and a few other internal upgrades. But don’t judge too quickly, because we’ve had some time to play with Nikon’s latest creation and the D5100 can certainly shoot along with the big boys of consumer cameras — read on past the break for our impressions and comparisons with the D7000.

Nikon’s New ƒ1.8 ‘Nifty Fifty’ Official at Last

Nikon’s new nifty fifty is a must-have lens for pretty much anyone (who owns a Nikon SLR)

Nikon’s widely-leaked new 50mm ƒ1.8G lens has finally been made official, and comes in at the reasonable, reasonable price of $220. If you have a Nikon SLR and are still using the horrible kit zoom lens, you should go place your order now. I’ll wait.

Back? Good. Let me tell you what you just bought (and thanks for trusting me, by the way). The main difference between this new “nifty fifty” and the almost decade-old ƒ1.8D is that it has an autofocus motor inside. This means you can use it with any current or recent Nikon SLR. The older lens lacks this motor and is instead driven by one in the camera, which cheaper bodies don’t have.

The other change is that the aperture ring has gone. For younger photographers who never used a ring on the lens to change the aperture, this isn’t a big deal. For oldies who find twisting a ring way easier than twiddling a dial, it’s a shame.

And that’s about it. The 50mm lenses have long been some of the sharpest (and cheapest) lenses available. This, coupled with the shallow depth-of-field that lets you isolate subjects from the background and the great low-light abilities of the ƒ1.8 aperture mean that everybody should have one. And if you put it on a crop-sensor, DX-format body, you get an awesome 75mm portrait lens.

So well done for ordering it. Now sit back and wait, because it’s not shipping until June 16th.

Stick-On Camera Grips for Shovel-Handed Shooters

Flipbac’s camera grips help you grapple with today’s tiny cameras

Today’s tiny, tiny cameras are very comfy to use. If you have tiny, tiny hands that is. The problem is that most of us don’t have pathetic T-rex-style paws but normal mitts with fingers that just can’t grip a digicam very well. The answer — aside from a thumb graft — is to add an extra grip.

These three grips come from Flipbac. They’re made from silicone and have a sticky 3M adhesive back that holds them firm but leaves no sticky residue when removed. The three models are all the same size — 38 x 22 x 6mm — but each comes with a different-shaped bulge. These shapes are “inspired by” the grips on the Canon G12, the Panasonic GF2 and the Samsung TL500.

Available in three delicious, chewy silicone flavors

Choose the one you think would be most comfortable for your big shovel-like hands, stick it onto the flat surface on the front of the camera and you’re done, now able to take pictures with one hand.

The very best part of this is that the grips cost just $10 each. In the world of overpriced photo accessories, that’s virtually free. Available now.
