The Olympus SZ-31MR iHS is a new travelzoom camera with a 16-megapixel back-illuminated CMOS sensor, a 25-600mm equivalent zoom lens, touch-sensitive screen, high-speed AF and Multi-Recording functionality. Equipped with two separate TruePic V image processors, originally developed for DSLR cameras, the Olympus SZ-31MR iHS is capable of simultaneously capturing Full HD movies and full-resolution stills. Its new iHS (intelligent, High-Sensitivity and High-Speed) technology is claimed to “dramatically improve” low-light performance, speed up camera response time, and enhance scene and subject recognition. “Combined with High-Speed Sequential Shooting (10fps) and high-speed autofocus, iHS reduces picture noise and enhances resolution and colour gradation,” the company says. The camera‘s touch-sensitive, 3.0-inch 920,000-dot LCD screen allows users to change the active AF point, shutter speed and zoom, or navigate the Live Guide controls by touch. Other highlights include a hand-held starlight mode and a dozen “Magic Art Filters”. The Olympus SZ-31MR iHS will be available in silver and black, priced at $399.99/£299.99.

The Olympus TG-820 iHS is a new water-, shock-, freeze- and dustproof compact camera with a 12-megapixel BSI CMOS sensor, a 28-140mm equivalent zoom lens and a 3-inch, 1,030,000-dot HyperCrystal III LCD screen with scratch-resistant, anti-reflective coatings. Olympus’ iHS technology builds on the speed of the camera’s back-illuminated CMOS imager and TruePic VI image processor to “dramatically improve” low-light performance, speed up camera response time and auto focus, plus enhance scene and subject recognition. HDR Backlight Adjustment takes a collage of separate photos and blends them into one perfectly exposed image regardless of difficult lighting. Other highlights include Full HD video recording with Multi-Motion Movie IS, an enhanced iAuto shooting mode and an on-board HDMI connector. The Olympus Tough TG-820 iHS will be available in a variety of colours at an estimated street price of $299.99/£269.99.

Sigma has updated its large-sensor compact cameras, the Sigma DP1 and the Sigma DP2, to incorporate the high-resolution sensor found in the Sigma SD1. This imaging chip features over 15.3 million sensor photosites with stacked red, green and blue filters (as opposed to a typical 16-megapixel Bayer sensor that has 8 million green-, 4 million red- and 4 million blue-sensitive pixels) for superior colour reproduction and resolution. In addition, the new versions boast totally redesigned lenses - a 19mm f/2.8 lens for the Sigma DP1 Merrill and a 30mm f/2.8 for the Sigma DP2 Merrill - with moulded-glass aspherical elements, “F” Low Dispersion and Super Multi Layer coating, and a telecentric optical design. The new generation name “Merrill” is a tribute to Foveon’s co-founder, the late Richard B. Merrill, who developed the original Foveon X3 Direct Image Sensor. Pricing to be confirmed.

The Pentax Optio WG2 and WG2-GPS are two new waterproof, dustproof and shock-resistant compact cameras.

Want to see exactly what the new Nikon P510 and P310 compact cameras look like in the flesh?

The Nikon P510 has a massive 42x zoom lens (yes, 42x) that provides a focal range of 24-1000mm. Unfortunately the early prototype that we got our hands-on was battery-less, preventing us from seeing just how far the lens extends at full zoom.

The Nikon P310 is a small and serious compact with a 24-100mm lens and full manual controls (although still no RAW format support). Again this was an early model with no battery.
