We've had some time with a pre-production D800 and have prepared a detailed in-depth preview. Nikon's latest DSLR boasts core technology borrowed from the top-end D4, married with a 36.3MP CMOS sensor that comfortably eclipses the rest of the DSLR market in resolution terms. As well as first impressions of handling and operation, and an in-depth look at the D800's specifications we've also dived a little deeper into the D800E, the D800's sister model, which lacks an anti-aliasing filter.

Canon has released three EF lenses, including an updated 24-70mm F2.8 II USM. The latest version features what is promised to be a more durable body, despite being a little smaller. In addition to this high-end full-frame standard zoom, there are completely redesigned semi-fast 24mm  and 28mm F2.8 primes, both of which feature USM focus motors and image stabilization. Ultimately, the most interesting thing about these launches is the fact that Canon feels the need to update various full-frame lenses, almost as if something likely to test the quality of its existing versions was in the offing.

Canon has launched the ELPH 530 HS and ELPH 320 HS, Wi-Fi and touchscreen versions of its recently released style compacts. The cameras, sold as the IXUS 510 HS and IXUS 240 HS respectively outside North America, have several different ways to allow wireless sharing to home networks, smartphones or the internet. The ELPH 320 HS, like its non-Wi-Fi  ELPH 110 HS brother, is a 16MP camera while the smaller ELPH 530 HS uses a 10MP section of the same 16MP sensor. The 530 HS uses Micro SD but this is less problematic, thanks to its wireless capabilities.

Canon has launched six 16MP A-series entry-level PowerShot cameras, completely refreshing the lineup. The models are best understood as three distinct groups within the range: the A810 and A1300 are traditional AA-battery A-series cameras with 5x, 28-140mm equivalent zooms, the A2300, A2400 and A3400 are slim cameras with the same lens and lithium ion batteries, and the A4000 tops the range with an 8x zoom.

Canon has launched its second waterproof rugged camera, the 12MP D20. It has a 5x, image stabilized 28-140mm equivalent zoom lens, featuring the company's latest 7-mode IS system. It also includes GPS and a 460,000 dot 3.0" LCD. The camera's back-lit CMOS sensor allows the D20 to shoot 1080p24 movies accessible with a dedicated movie record button. Unlike the company's D10, the D20 is a relatively small, periscope-lens card camera. It is waterproof to a depth of 10m and shockproof from a height of 1.5m.
