Tokina AT-X M35 Pro DX
Tokina has announced a new macro lens for Canon and Nikon crop sensors, the AT-X M35 PRO DX. Equivalent to a 53.5mm focal length on Nikon DX and 56mm on Canon APS-C, this lens revives the 'normal' macro segment which has been sadly absent in recent years, at least for crop sensors. A focus limiter is present, accelerating operation when used for regular photography, and Tokina's Focus Clutch design makes switching from automatic to manual focus a snap - literally. The lens is due to be available from December 21st at a price of ¥68,000 (approx US $600). Pricing and availability for markets outside Japan are yet to be announced. (12:40 GMT)

Tokina AT-X 116 Pro DX
Another interesting lens announced by Tokina is the AT-X 116 Pro DX, a wide zoom for Nikon and Canon crop sensor cameras boasting a focal length of 11-16 mm and constant f/2.8 maximum aperture. Whilst the zoom range is not exactly what you might call extensive, this lens is likely to generate considerable interest with its 17-25 mm approx. equivalent focal length (on Nikon DX, Canon APS-C users will get around 18-26 mm). Priced at ¥90,000 (around US $800), the lens will be available in Japan from December 21st. (12:40 GMT)

Sigma 4.5mm EX DC Circular Fisheye HSM
Sigma has for the first time marketed a true fisheye optic for crop sensors, projecting a circular 180° image onto APS-C sensors. The new lens sports a focal length of 4.5mm and maximum aperture of f/2.8, HSM silent focusing and SLD low-dispersion lens elements. Aside from the 'edgy' skateboarding shots and frankly unflattering portraits often seen, circular fisheyes are actually quite useful for astrophotography and scientific applications. Pricing and availability is yet to be announced. (00:00 GMT)

10mm F2.8 EX DC Fisheye HSM
The other type of fisheye lens available is the diagonal variety which squeezes a 180° angle of view into a standard rectangular format. This new 10mm F2.8 EX DC Fisheye HSM from Sigma is just such a lens. That said, it captures a true 180° vista only when mounted in front of a Nikon DX sensor - users of Canon and Sigma DSLRs make do with 167° and 154° respectively. A built-in lens hood and HSM focusing are here and the lens will focus down to 1.8cm (0.7 in) from the front surface of the lens giving a reproduction ratio of 1:3.3. (00:00 GMT)

Mňa najviac zaujala tá tokina 11-16/2.8. Uvidíme ako na tom bude s ostrosťou a aberáciou na plnú dieru. Zatiaľ papierovo zaujímavé sklo.
