Pentax has officially announced the K-30 weather-sealed mid-level DSLR. It's built around the same updated 16MP sensor and processor as the K-01, so should offer impressive image quality and borrows many of the features from the more expensive K-5. It can shoot continuously at up to 6 frames per second, has a maximum shutter speed of 1/6000th of a second and can capture video at 1080p30. We've had a pre-production K-30 in the office for a couple of days and have prepared a preview looking at what it offers.

Pentax has announced the DA 50mm f/1.8, an affordable telephoto prime lens for APS-C interchangeable lens cameras. The lens offers a 76.5mm equivalent field of view on the company's DSLRs or K-01 cameras. The lens is designed to look like Pentax's premium 'Limited' prime lenses but features a plastic lens mount. The lens is only 38.5mm long at its shortest, and will sell for around $249.95, making it a small and relatively inexpensive addition to a camera bag.

Apple has taken the well-known iPhoto app that’s bundled with Apple computers and adapted it for the iPad and iPhone. Although the iPhoto app offers a range of image editing tools including global and localised adjustment control (using multi-touch tools) there’s a lot more to it than that. Joanne Carter takes a look.

Photographer Andrew Kane found himself having to report damage to the Nikon D4 he'd rented this weekend, after it was attacked by a grizzly bear. Kane had the presence of mind to document the attack, using his D700 and 70-300VR that he had slung around his neck - grabbing some impressive sharp images of the bear mauling the rented kit. LensRentals seem satisfied with his explanation - Roger Cicala has blogged that replacement gear is already on the way to Kane.

Just Posted: our hands-on preview of the Panasonic 12-35mm F2.8 fast standard zoom for Micro Four Thirds. It's the first constant-aperture standard zoom for a mirrorless system - helping strengthen the position of the system developed by Panasonic and Olympus. We've been using a pre-production version of the lens on both makers' cameras, and have prepared a hands-on preview and a small gallery of sample images.

Panasonic has formally announced a 12-35mm F2.8 lens for the Micro Four Thirds system. The LUMIX G X VARIO 12-35mm/F2.8 ASPH./POWER O.I.S offers a traditional 24-70mm equivalent field-of-view, and is the first constant-aperture standard zoom for a mirrorless system. The lens is the latest in Panasonic's premium 'X'-branded range and uses the company's latest Power O.I.S optical stabilization system. It will be available in August, pricing details are not yet available.

The restriction that limits video recording in digitial cameras to 30 minutes could be abolished if the World Trade Organization's Information Technology Agreement (ITA) is expanded. Several countries, including the USA, have begun informal talks to extend the scope of the ITA to include products that are currently subject to tariffs and duty. At present, digital cameras' video cuts off after 30 minutes to avoid them being classified as video cameras (which attract 5.4% duty). If the video cameras are added to the ITA, this distinction would no longer matter. (via Nikkei)

Samsung has announced the US prices for its latest 'Smart' Wi-Fi enabled NX mirrorless cameras, the NX20, NX210 and NX1000.

The NX210, meanwhile, will cost around $899 with the same lens.

Just Posted: our hands-on preview of the Sony NEX-F3. The F3 is Sony's latest entry-level model, replacing the NEX-C3. It's built around the company's second-generation 16MP CMOS sensor, as featured in the NEX-5N and gains a built-in flash.

We've been using an F3 for a couple of days - read our hands-on preview to find out what we thought and to see the images we shot.
