Sigma recently released a demo video showing software of the late USB lens docking station in action. This dock is a very special product as it will allow users to adjust focus if there is a need for it (usually there is). Almost all modern DSLR cameras have the option to adjust AF accuracy, but often only as a single setting for every lens. This is a problem with zoom lenses since most tend to missfocus by different degree depending where in the zoom or focus range they are. Sigma USB dock will allow to set AF compensation at up to 4 focal lengths and at 4 different focus positions independently. There is also an option to adjust optical stabilization , focus limiter and AF speed. Click “continue reading” to view video:

While the big two (Canon & Nikon) successfully pursue the image of boring traditional companies, others like Sigma try to be inventive and gain a piece of market for themselves. Today, Sigma announced a new extraordinary lens: the 18-35mm F/1.8 DC HSM for APS-C sized sensors. Yes, this is not a typo; this zoom lens has constant F/1.8 aperture. As far as I know, no other photography lens has such aperture, the closest being Olympus with the two of their F/2 zoom lenses.
Today is a day for Sony announcements. After RX1 full frame compact, next in line are three new NEX lenses; a wide angle 10-18 f/4, callapsable 16-50 power zoom and a 35mm f/1.8 prime lens. With the latest additions, a popular NEX system has 13 lens options (together with wide and fisheye adapters for 16mm).
Photokina is the world’s biggest and most anticipated imaging fair that takes place every two years in a German town of Cologne (Köln). Industry leaders, traders, professionals and amateur photographers will all gather at September 18 to view and try the latest photographic equipment on the market. I have prepared a short list of expected announcements and rumors. Some cameras or lenses might be announced before the show, but the public will be able to see them for the first time at the fair.
Sony has announced a new DT telephoto lens – SAL55-300 f/4.5-5.6. DT designation indicates it is usable only on APS-C sensor that require smaller image circle than full frame sensors. In 35mm equivalent, this lens has a reach of 82 – 450mm, which makes it 5.5x zoom lens. The zoom range makes it usable for many shooting scenarios, from wildlife and sport to portraits, both still image and video and will ideally complement 18-55 kit lens sold with most Sony SLT’s or DSLR’s.
Latest addiction to the range of micro 4/3 mount lenses is this new 75mm f/1.8 single-focal lens. With its 150mm field of view (in 35mm equivalent) and large f/1.8 aperture it is optimized for studio or outdoor low-light portraits, indoor sports or concert/stage photography. It should deliver beautiful out of focus backgrounds thanks to nine blade aperture. Optical design incorporates 10 lens elements in nine groups, including three ED (Extra-low Dispersion) elements to correct aberrations.
