Canon's new midrange 24-70mm zoom gets stabilization

Two new higher-end but not top-end lenses will arrive in December, the $1,500 EF 24-70mm f/4L IS USM and the $850 EF 35mm f/2 IS USM, Canon said today.

The 24-70mm f4 lens, though not inexpensive by any means, extends a Canon tradition of offering intermediate models for enthusiasts and pros who don't necessarily want to pay more for top-end lenses -- in this case, the alternative is the $2,300 Canon EF 24-70mm f/2.8L II USM introduced in February, whose f2.8 aperture enables photography in low-light shooting and with a blurrier background … Read more

Nokia culpa: Phony Lumia 920 video prompts ethics probe

Nokia committed a major gaffe in promoting its Lumia 920, and now the company says it's trying to figure out why.

Last week, the company unveiled its new Windows 8 Phone handsets, with the Lumia 920 starring as its flagship device. Touting the phone's optical image stabilization (OIS), Nokia released a promotional clip supposedly comparing video shot by the 920 using OIS with video shot by a phone without OIS.

But after The Verge noticed an odd reflection in the clip, Nokia fessed up that the OIS-flavored video was actually shot by a normal video camera and not … Read more

Canon overhauls 24-70mm lens, stabilizes 24mm and 28mm primes

To IS or not to IS?

That is the question Canon faced when deciding whether to put image stabilization in a trio of new lenses it announced today. Curiously, it reached two different answers.

For a rework of a highly regarded professional-grade staple, the 24-70mm F2.8, Canon decided against image stabilization, evidently discouraged by drawbacks such as weight, complexity, and expense. But for new incarnations of its 24mm and 28mm F2.8 lenses, IS is now an option.

Canon's new EF 24-70mm f/2.8L II USM follows the pattern of several lens upgrades in recent years: spruce … Read more

Kungl iPhone tripod mount doubles as a case

Want to mount your iPhone on a tripod? There are lots of third-party accessories that can help, but few are as practical or affordable as the Kungl iPhone Tripod Mount.

Lest you think it sounds crazy to connect a smartphone to a tripod, consider this: the iPhone 4 sports a 5-megapixel camera and can capture 720p video, while the 4S raises the bar to 8 megapixels and 1080p--and even brings image stabilization to the table.

The latter might seem to obviate the need for a tripod, but if you want the sharpest photos and smoothest video, nothing beats one.… Read more

Microsoft researchers battle blurry pix

For a long time, blurred pictures caused by shaky hands were one of the biggest issues for many photographers. Sure, there are optical and sensor-shift image stabilizers (IS) to help shutterbugs get sharper shots, but their effectiveness is limited: Typically, IS won't work well if you're shooting at 1/10 second and slower, and this figure is affected by the focal length of the lens as well.

Instead of working on hardware IS, a team of Microsoft researchers took the software approach and tackled this digital-imaging issue by coming up with a set of algorithms to help sharpen … Read more

Five inexpensive ways to end blurry snapshots

Despite point-and-shoot camera manufacturers' best efforts to reduce the effects of hand shake--digitally, optically, and mechanically--as long as you're holding the camera there's a very good chance you'll end up with blurry shots. Add in softening caused by noise reduction at higher ISO sensitivities, and getting a sharp shot of moving subjects or in low-light conditions can be tricky. The disappearance of viewfinders from compact cameras doesn't help things either as it encourages you to extend your arms to use the LCD.

Taking the camera out of your hands and putting it on a tripod or other support is one of the best ways to improve your odds. However, when I suggest this to point-and-shoot users I typically get in response that it's not practical to carry a tripod and it kills the point of having a very portable camera. But the solution is easy: get a very portable mini tripod.

Below are five favorites ranging in size, price, and flexibility, and though they aren't all technically tripods, they'll certainly help keep your pocket camera still whether you're behind or in front of it.

In lieu of buying a support, there are free options for helping control hand shake. Look for a lamp post, wall, tree, or any solid vertical structure you can lean against for support. Don't fully extend your arms, but instead pull them into your body as closely as possible with your elbows tucked into your sides or rest on a ledge or wall. Also, even if your camera has a lot of zoom range and optical image stabilization, it's always better to move yourself closer to a subject if possible than using your zoom. Lastly, if you use a tripod or anything else that's stable to support your camera, be sure to shut off any in-camera image stabilization--in this case, more stabilization is not better. … Read more

Canon unveils optical stabilizer improvements

In the first significant improvement Canon's made in its optical stabilization technology in a few years--I think the last major update was the SuperRange OIS in its camcorders--the company announced a new Hybrid IS technology that adds angular velocity sensing to its current bag of OIS tricks. While its IS system already has a sensor to detect rotation, the new velocity sensor is intended to detect the speed of rotation and thereby compensate more precisely. (Here's a simulation of how the current lenses work, and here's a nice PDF white paper on how angular velocity sensors work, … Read more

Binoculars overcome caffeine addiction

Whether it's because of too much caffeine or advancing age (both, most likely), it's become increasingly difficult for us to hold a steady shot these days with the usual point-and-shoot cameras. The same is true with our binoculars at the track, when we're watching yet another nag come in last and ruining the trifecta we so brilliantly calculated.

So we were initially happy to see what's billed as "the world's most powerful image-stabilizing binoculars," which has something called a "passive mechanical stabilizer" that's supposedly "designed to counteract the vibrations … Read more

Fuji intros Sensor-shift IS in newest batch of compacts

Summer is in full swing and the season is heating up with new camera announcements. Fuji steps to the plate with five new models that follow the trend toward more megapixels and slowly growing zoom ranges, while adding to the company's set of signature features. As with the company's PMA introductions, all the new cameras will be able to store images to both xD Picture Cards and SD cards, as well as SDHC cards.

With the Finepix F50fd, Fuji is introducing a new version of the company's face-detection technology, which Fuji calls Face Detection 2.0. While … Read more
