Nikon and photographer Sandro have teamed-up to showcase the new D800’s video capabilities. Joy Ride is a short film shot with the D800 in a variety of lighting conditions, including a motorcycle sequence where the D800 was strapped to the bike. There’s also a behind-the-scenes video which goes into a little more depth about how the impressive Nikon D800 was used.

Pentax have released an official video interview with Marc Newson, designer of the innovative Pentax K-01 compact system camera. In addition we have an exclusive video of Marc talking about the K-01 at last week’s UK press launch. Click through to see both videos.

Nikon has posted a number of full-resolution sample photos taken with the brand new Nikon D800 and Nikon D800E digital single-lens-reflex cameras. All of the sample images were captured in raw format and converted using Capture NX 2. The downloadable JPEG files range from 17.01 to 33.06 megabytes in size, and are apparently meant to demonstrate the resolution capabilities of the 36-megapixel FX sensor, first and foremost (which also means that there are no real high-ISO samples on display, with ISO 640/29° being the highest sensitivity setting used). You can download the Nikon D800 and Nikon D800E sample images from the websites below.

The D800 has a high-resolution 36.3 megapixel full-frame 35mm sensor that Nikon claim makes it a rival to medium-format cameras, especially the D800E version which removes the anti-aliasing filter to achieve even more detail. Nikon UK predict that 10% of Nikon D800’s sold will be the special E version, which will be available at more specialist retailers.

The D800 still offers similar noise levels to the D700 (which carries on alongside the D800) and outperforms the D7000. ISO 50 is claimed to be better than Kodachrome, said Nikon UK’s James Banfield at yesterday’s launch event, with ISO 100 delivering the best quality of any ISO speed.

With high-speed SD and Compact Flash dual slots, the D800 offers maximum flexibility for a wide user base, although the brand new XQD format has been reserved for the flagship D4 camera.

Canon has updated its EF 24-70mm f/2.8L USM to Mark II, and introduced two new image stabilised wide-angle primes. The Canon EF 24-70mm f/2.8L II USM ($2,299.00) features an all-new optical design that’s claimed to deliver exceptional sharpness and reduced aberrations thanks to the inclusion of both ultra-low-dispersion and super ultra-low-dispersion elements. Other highlights include a dust/moisture resistant construction, fast and silent AF with manual focus override and a nine-bladed circular aperture - but no image stabilisation. The Canon EF 24mm f/2.8 IS USM ($849.99, pictured) is a medium-high-speed ultra-wideangle prime with Super Spectra coatings, ultrasonic focus motor and a circular aperture. The other new fixed-focal lens, the CanonEF 28mm f/2.8 IS USM ($799.99), has a similar feature set but a slightly tighter field of view. Unlike the zoom, both primes feature image stabilisation offering a claimed 4-stop advantage over lenses without IS.
