Wide Zoom Range

The new Tokina AT-X 12-28 mm F/4 lens has a super-wide to standard zoom range while maintaining a constant fast f/4.0 aperture. This makes it a very versatile lens for different photo applications such as scenery, street scenes photography and event coverage. The lens is designed for DSLR cameras with APS-C (DX) sized sensors.

New Optical Design

A new optical design using aspherical elements and super-low dispersion glass matches even the highest mega-pixel DX sensors cameras available today.

One aspherical lens element is positioned in the front group. This together with another precision molded glass aspherical lens element placed in the rear group ideally focuses marginal light rays and maintains sharpness at the edges while also correcting distortion. The use of two different SD (Super-low Dispersion) glass elements, type FK01 and FK03, corrects chromatic aberration. The combination of all these specialized elements in the optical design yield excellent sharpness and[...]

Preview based on a pre-production Canon EF-M 11-22mm f/4-5.6 IS STM

It's now almost a year since Canon unveiled its first foray into the mirrorless camera sector, the EOS M. The camera was launched with two lenses, the EF-M 18-55mm f/3.5-5.6 IS STM kit zoom and the EF-M 22mm f/2 STM 'pancake' prime. But while most other manufactures have gone out of their way to provide 'roadmaps' of upcoming lens releases in an attempt to convince potential buyers of their commitment to these new systems, Canon has remained stubbornly quiet. But now EOS M owners have a new lens to consider: the EF-M 11-22mm f/4-5.6 IS STM wideangle zoom.

The lens offers a zoom range equivalent to 18-36mm on full frame, which is a little less ambitious than its closest competitor, the Sony E 10-18mm F4 OSS (15-24mm equiv). To an extent this is a trade-off for its relatively compact design; it uses a retracting barrel reminiscent of the Olympus M.Zuiko Digital ED 9-18mm 1:4.0-5.6, and is about the same size as the 18-55mm[...]

รายละเอียดสินค้า

The "old" Sigma AF 17-70mm f/2.8-4.5 DC is/was one of the more popular standard zoom lenses. It provides a longer reach than the average "kit" zoom lenses (usually 18-55mm f/3.5-5.6 variants) yet it's a bit more affordable than the typical mid-grade zoom lenses a la Canon EF-S 17-85mm f/4-5.6 USM IS or Nikkor AF-S 16-85mm f/3.5-5.6 VR ... and it's 2/3 f-stops "faster". In our previous tests it performed pretty well. But the initially released version relied on a fairly dated screw drive, which made it an unattractive choice for most Nikon DX users. Sigma upgraded the F-mount version of the lens to an HSM drive (the Canon variant uses a DC motor instead), but still the lens lacked one important feature: optical image stabilization. Well, it seems as if Sigma agreed here because they eventually released the Sigma AF 17-70mm f/2.8-4 DC HSM OS.
