Researchers develop ‘liquid pistons’ for cameras, medical use

It may still be years away from any sort of practical use, but a team of researchers at the Rensselaer Polytechnic Institute have developed some so-called “liquid pistons” that they say could shake up everything from cameras to medical devices. Those pistons consist of some droplets of “nanoparticle-infused ferrofluids,” which are able to oscillate and precisely displace a surrounding liquid. In the case of a camera, that could be used for a liquid lens of sorts (as seen at right), and the researchers say the same technology may one day even be used for implantable eye lenses. The possibilites don’t end with optical uses, though — the researchers say that the precise ability to pump small volumes of liquid could also be used for implantable drug-delivery systems that would be able to deliver tiny doses at regular intervals. Of course, there’s no indication as to when any of that might happen — in the meantime, you can occupy yourself with the brief but oddly hypnotic video after the break.

A Fancy Lens for Your Flip

flip lens.jpg

Okay, it’s not quite the overkill of the iPhone video rig we just showed you, but I kind get the sense that this thing defeats the purpose of the Flip. If you’re looking to get more pro-level shots out of your pocket camcorder, however, Bower has you covered.
The company designed this 0.45x wide angle lens with the Flip in mind. It works with the Flip Ultra,Ultra HD, Mino, Mino HD, and Slide HD. The lens attaches magnetically to the camera. 

152 Zoooooming Photographs [Photography]

Zooming. Most people only do it before or after taking a photograph—never during. Well here are 152 remarkable pieces of proof that most people are wrong. Zooming while taking a photograph is a surprisingly versatile, inevitably eye-catching technique. More »

The Best Budget Camera Lenses [Bestmodo]

If you’re shopping for a new lens of some sort, you’ve come to just the right place. Here’s ThePhoblographer’s list of the best lenses you can get your hands on without breaking the bank. More »

Photo Gift: Fast Mainstream Zoom Lens

f28 zoom lens.gif

Your DSLR probably came with an affordable zoom lens worth $200 on its own. But its optics are so-so. The largest aperture, or biggest light-gathering setting, is relatively modest at its widest-angle setting and falls further as you zoom toward telephoto. The downside to the faster lens is the price, $500 to $1,350, and some makers nick you another $25-$50 for the lens shade. The f/2.8 lens is also bigger and bulkier as you can tell from the Canon 17-55mm f/2.8 and 18-55mm f/3.5-5.6 lenses above. With a high-speed zoom, you can do most all your indoor photography without resorting to using a flash, so the photos will look more natural. And the optics are better.

Lensbaby System Bag Keeps All Your Lenses in One Basket

Lensbaby’s new bag is like an oversized egg-box for your precious light-bending optics. The long padded stick has movable sections inside to hold up to four lenses, and there is a mesh section for small accessories, an external zippered pocket for other extras, and the ends themselves open with flaps for quick access to an oft-used lens. Finally, you can attach a shoulder-strap and stack multiple bags using interlocking Velcro straps.

For just $40, Lensbaby owners will probably snap this up. I have a few of the focus-distorting lenses and they tend to rattle around in a bigger bag, and it seems like overkill to actually lug a proper camera-bag just to carry these and a camera body. The bag also makes swapping out the changeable optics a little easier, as you don’t have to juggle their little plastic containers, too (pro tip: don’t forget at least one of these containers’ lids. It is also a removal-tool).

What I like best is that it is slimline, and comes with a strap included but not attached. Perfect for tossing inside a stealth camera-bag.

Available now.

Lens Bracelets: Too Nerdy Even for a Geek?

Just how dorky do you have to be to wear one of these lens bracelets? Pretty damned dorky, I’d say, and that’s coming from someone who is still seriously considering making a bracelet from a bike-chain.

The Lens Bracelets are made from silicon, and ribbed to further emulate the nodules that help focussing on a real lens. They’re both the same size, but styled as either a 50mm prime or 24-70mm zoom. Would anyone really wear one of these? A bike-chain bracelet is at least kind of cool, in a tough-guy, mechanical way. Jewelry in the shape of a lens-ring, though? You may as well just become celibate right now.

The bracelets are $10 each, or $15 for the pair, available now.

Olympus Tweaks ‘Pen Lite’ With Faster, Quieter Lens, Higher ISO

Hey, Panasonic, take a look over here. This is how you upgrade a successful, well designed camera. You add almost no changes, boosting the maximum ISO from 3200 to 6400, for example, and perhaps tweaking the color and shaving some weight to make it look a little different from its predecessor. What you don’t do is take possibly the best camera you ever made (GF1) and dumb it down until it is little more than a point-and-shoot with interchangeable lenses (GF2).

Olympus did it right, and the paragraph above contains almost all the tweaks it made to the already good Pen EPL-1. In fact, the new camera does’t even get a new name, just an extra letter: EPL-1s.

A bigger change is the new kit lens, the 4-42mm II ƒ3.5-5.6 which shrinks down to 454g (one pound) and gets a video-friendly silent AF motor which is also faster to focus than the old model.

The EPL-1s can also be had in a nasty burgundy/red colorway.

The new kit is launching in Japan, hopefully making its way overseas soon.

Samsung adds prescription lens option to its active shutter 3D glasses

If the only thing holding you back from that new 3DTV purchase was the inconvenience of slipping the 3D glasses over the regular old 2D glasses you already wear, Samsung is the first major manufacturer with a solution now that it’s unveiled a prescription version in Korea. The SSG-R2200 models appear to be very similar to the company’s other active shutter 3D glasses in various shapes and sizes, but they’re made to order from an optometrist. We know this is something several companies have been working on and expect to see these available in the US eventually as well, but we’ll have to see a pricetag of some type before we decide if rocking the dual specs or just sticking with 2D is the best option.

Lens Guard, The Ugly Duckling of Protective Covers

The very best thing about the DeluxeGear Lens Guard is that it looks like it was designed and made by a three-year old. Take a look: it’s as if this protective cover had been squished out of Play-Doh and stuck straight on the front of the lens.

In fact the Lens Guard is a little more high-tech than that. An inner neoprene core is covered with Santoprene, a cross between rubber and polypropylene which can be molded when hot and sets to a bendy, waterproof rubber-like material. According to Wikipedia, Santoprene is also used to make the blades of “training knives, swords, and bayonets” which is awesome.

Back on the camera, the Lens Guard is like an extreme lens-cap. You pop the cosy over the end of the lens and the shock-absorbing cover soaks up bumps, whilst shrugging off dust and water. If you’re the kind of person who keeps a lens-hood permanently attached to your lens not to reduce flare but to protect the front element from whacks and smack, this is for you.

The Lens Guard comes in three sizes, to fit lenses from 2.5-inches to 3.9-inches in diameter, all of which cost $15. Or you could just buy a tub of Play Doh and put the kids to work.
