DIY macro lens for your phone's camera

I came across this tutorial last week that showed how you can turn an ordinary phone camera into something capable of capturing extreme close-up macro photos. You know, the ones where you can see the hairs on a fly's head.

After the dust settled on the iOS 6 release, over the weekend I dug through the junk drawer in my kitchen and found an old laser pointer. I then located a bobby pin in the bathroom and some painter's tape in the basement. I now had the three necessary ingredients and the time to see if this thing … Read more

Schneider widens range with SLRs, Micro Four Thirds lenses

COLOGNE, Germany -- Every 99 years or so, a company has to shake things up a little bit.

Thus it is that Schneider Kreuznach, a high-end lens brand founded in 1913 that's been focused on cinema, medium-format, and large-format markets, unveiled four lenses for more ordinary 35mm SLRs, three for Micro Four Thirds cameras, and even a polarizing filter for iPhones. The lensmaker, part of the Jos. Schneider Optische Werke, unveiled the lenses at the Photokina show here.

Its earlier lenses for conventional SLRs were the company's relatively exotic Super Angulon line, tilt-shift models that can enable perspective … Read more

Canon 200-400mm supertele lens due this year -- maybe

COLOGNE, Germany -- A year and a half ago, Canon announced it was working on a 200-400mm telephoto zoom lens with a built-in 1.4X extender. But since then, there's been nary a peep.

Well, there's a peep now, Canon shooters jealous of Nikon's 200-400mm will be pleased to know.

The plan is to release it this year, said Mike Owen, communications manager for Canon's professional imaging department in Europe. He spoke at a Canon press conference yesterday at the Photokina show here.

But Owen was quick to add a caveat: "We're anticipating that, … Read more

Medium-format update: Phase One launches 645DF+ camera

COLOGNE, Germany -- Phase One and Mamiya Leaf, the medium-format camera maker it controls, announced its new 645DF+ medium-format camera with new mechanics and improved focusing abilities.

The companies also announced at the Photokina camera show here the new Schneider Kreuznach 28 LS f/4.5 Aspherical, a very wide-angle 28mm leaf-shutter lens built by Schneider Kreuznach for the Mamiya Leaf-Phase One cameras. The camera and the lens are priced the same; each costs $5,990 or 4,290 euros, and each will ship in October.

Compared with the earlier 645DF, all moving parts of the 645DF+ have been completely … Read more

Tamron's new full-frame lenses: 90mm macro, 70-200mm tele

Tamron announced today it's brought vibration compensation to two full-frame lenses, the 70-200mm F/2.8 Di VC USD telephoto and the SP 90mm F/2.8 Di VC USD macro.

Both of the lenses will ship by the end of the year for Canon, Nikon, and Sony cameras, Tamron said just ahead of the Photokina 2012 show, a major camera event held every two years in Germany. The company didn't disclose prices.

Vibration compensation -- known as vibration reduction at Nikon and image stabilization at Canon -- shifts a lens element to counteract camera shake. It can … Read more

Episode 13: the Nexus 7 tablet is a delicate flower

In the Season 2 premiere of Always On, the Google Nexus 7 takes a beating. Well, it wouldn't be fair to say it takes a beating. It receives a beating, and frankly, doesn't handle it very well. It's one of our more dramatic Torture Tests, and I think it points out that sometimes, you do get what you pay for when it comes to quality and durability. The Nexus 7 is a great tablet in many respects but, well. It's not the toughest little thing. You'll see what I mean.

We'll find out in … Read more

Nokia City Lens app for Windows Phone 7 zooms in on local shops

Owners of virtually all Nokia Lumia phones will be able to discover local businesses via the company's new City Lens augmented reality.

Shown off by Nokia last week, City Lens overlays nearby businesses on the screen when you point your phone in their direction. Tapping a specific business reveals full details, including contact information, reviews, walking distance, and directions.

Though demoed for the upcoming Windows Phone 8 Lumia 920, the new app is actually available as of yesterday for the current Lumia 900, 800, and 710 Windows Phone 7 handsets. Owners of any of those phones can download City … Read more

Operation is easy. Simply twist on the knurled "zoom ring" of the lens and the ring of a bell will alert you when the countdown is complete. The device is fully mechanical and does not require batteries to run. … Read more

Nokia video hints at City Lens augmented reality app

Nokia is touting its City Lens augmented reality app through a brief, teasing video clip.

The clip on You Tube features a woman walking down a city sidewalk as an ad for a nearby shoe store pops up, complete with ratings and recommendations from her socially networked friends. With its emphasis on a local business, the clip seems to be a clear reference to City Lens.

Dubbed an augmented reality app, City Lens displays nearby stores and other businesses when you point your phone in a certain direction. The phone's camera displays the view around you with an overlay … Read more

X-cap: Never lose your lens cap again

The X-cap lens accessory can be mounted on interchangeable lens cameras that use retractable zoom lenses, such as Panasonic's 14-42mm pancake zoom, that require lens caps. Unlike conventional lens caps, the X-cap has a tiny mechanism below that activates the X-cap's lens opening when it's extended, and closes when it's retracted.

We think this is a very handy accessory as it means not having to remove (or lose) your lens cap ever again during a photo shoot. No details have been released yet on price or availability, but you can see the X-cap in action below. … Read more
