After keeping wildlife and sports photographers waiting for years, Canon has put a price tag on its 200-400mm supertelephoto lens with an unusual built-in 1.4x telephoto extender.

And it's not cheap: $11,799, at least on B&H Photo's preorder page for the Canon EF 200-400mm f/4L IS USM Lens with Internal 1.4x Extender.

Canon one-ups Nikon's $6,400 200-400mm lens with the 1.4x extender, which changes the Canon lens range to 280-560mm with a f5.6 aperture.

The built-in extender can be engaged by flipping a lever, a rapid operation that … Read more

When you're young and observing or experiencing abuse, especially when it involves people close to you, it can be hard to find the strength to talk to someone about it. An innovative new advertisement could help direct children -- without alerting their parents or others who may be threatening them -- that there's a way to seek help.

Spain's ANAR Foundation (Aid to Children and Adolescents at Risk) created an anti-abuse ad that uses lenticular printing to display two pictures that differ based on the viewer's height. The group created the ad to reach abuse victims who might be accompanied by their aggressor. … Read more

Admit it: Whenever you see someone using their iPad as a camera, you giggle. Maybe even snicker. That two-handed grip and big ol' viewfinder screen, that's just comedy. Especially when something like this happens.

On the other hand, the iPad 3, iPad 4, and iPad Mini all have a respectable 5-megapixel sensor, an IR filter, face detection, and some other solid digital-photography features. All that's missing is a zoom lens. (The iPads do offer digital zoom, of course, but that's to be avoided at all costs. It ruins photos.)

Enter Photojojo, the outfit known for making smartphone … Read more

Aiming to make it easier for photography enthusiasts to evaluate photo gear, DxO Labs today announced a new method of measuring lens sharpness it hopes will make more intuitive sense.

The idea, called the perceptual megapixel, shows how much of a camera's original sensor resolution a particular lens can preserve when factors such as lens sharpness, optical defects, and sensor pixel size are taken into account.

One example the company provides: on a 21.1-megapixel Canon 5D Mark II, the Sigma 35mm F1.4 DG lens gets a score of 17.2 perceptual megapixels and the much higher-priced Carl … Read more

Photography diehards and fans of printed T -shirts will like Dodge and Burn's latest camera-inspired collection. The New York-based company's latest Evolution TLR design highlights the history of the Twin Lens Reflex camera, a medium format film camera used in the '60s.

The site also offers a variety of other print designs, from the iconic Leica rangefinder camera to the classic SX-70 Polaroid film camera. Each shirt is printed using plastisol inks to create designs with textures that have a vintage and worn-out effect. … Read more

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

Lens cleaning equipment such as blower brushes and compressed air can take up quite a bit of space in your bag. The folks at Digital Camera World have come up with a novel DIY way of keeping things compact by transforming paintbrushes into portable tools for cleaning off minute particles when shooting in dusty environments.

All you need is an inexpensive paintbrush that's readily available at any craft shop.… Read more

Smartphones have rarely been accused of being elegant cameras. Tablets are even more troublesome. Sometimes, it would be easier to hold your device flat and snap a picture. Try that now and you'll get a lovely shot of your feet. Try it with a HiLO right-angle lens, and you'll get a real photo.

The HiLO hides three lenses and a prism inside that allow the image to bounce into the correct part of your camera. An app is also part of the Kickstarter project, so you'll be able to quickly correct for the image mirroring caused by the prism.… Read more

When photo enthusiasts entering the digital SLR market ask me whether they should go for Canon or Nikon, one of the points I often raise is Canon's appealing choice of high-end but not top-end lenses.

Well, Nikon just undermined that potential selling point. At the Photo Plus Expo show today, it announced its AF-S Nikkor 70-200mm f/4G ED VR, a telephoto zoom lens that provides a competitive answer to Canon's superb EF 70-200mm f/4L IS USM.

Let's be clear here. These are still professional-grade lenses, and they aren't cheap. Canon's costs about $1,… Read more
