The lens has a 180 degree field of view and is now available for Sony/Minolta and Pentax mounts as well as Sigma, Nikon and Canon DSLRs and carries an MSRP of $1,400.00

 

  • The second fisheye lens, is the10mm F/2.8 EX DC Fisheye HSM, is also designed for use on DSLRs with APS-C size sensors.

Sigma is offering a couple of new telephoto zooms including the APO 70-200mm F2.8 II EX DG MACRO HSM. The lens features SLD (Special Low Dispersion) and ELD (Extraordinary Low Dispersion) glass elements to offset possible aberrations and multi-layer coating has been added to reduce flare and ghosting. Of note is the fact that the length of the lens remains constant during focusing. Designed for Pentax and Sony, and Olympus/Four Thirds mounts, the 70-200mm lens is equipped with a tripod socket, accommodates Sigma APO teleconverters and comes bundled with a case and hood. MSRP is $1,200.00.

Sigma’s APO120-400mm f/4.5-5.6 DG OS HSM lens is available with Canon, Nikon or Sigma mounts. The lens, with a minimum aperture of f/22, utilizes Sigma’s original Optical Stabilizer (OS) function. A minimum focusing distance of 59.1 inches is available throughout the entire zoom range. The lens has an MSRP of $1,270.

 

For additional telephoto reach, check out Sigma’s APO 150-500mm f/5-6.3 DG OS HSM lens. Like its 120-400mm sibling, this lens is equipped OS to help keep images shake- and blur-free.

If you’ve been hoping for an optically stabilized lens then you should be clapping your shaky hands in happiness right now. The 18-250mm F3.5-6.3 DC OS HSM lens offers image stabilization in both the camera body and the lens. There are also models that fit Canon, Nikon and Sigma bodies without the extra IS.

Nikon 50mm f/1.4G or Sigma 50mm f/1.4 HSM

Recently, Nikon just launches their new 50mm f/1.4G lens. This lens has been long waited by Nikon fans. But is this lens a lot better than its predecessor? Nikon 50mm f/1.4D ? or Sigma 50mm f/1.4 HSM?

What is the improvement?

  1. First, this lens will work with Nikon D40, D40X and D60 digital slr camera.
  2. Second, it has a faster focusing due to AF-S motor
  3. Third, it is sharper wide open.
  4. Fourth, it produce better color-contrast

According to Tom Iancu, a Nikon user who posts review in Amazon.com, the extreme sharpness of this lens has a trade off. The bokeh or blur in the background is not smooth. On the other hand, the Sigma 50mm f/1.4 (slightly cheaper by the time I write the article) is not as sharp wide open, but it create a smooth, buttery bokeh.

About the build quality, Sigma is better. It feels tougher, but also heavy and bigger (520g vs 290g).

So it boils down to what you like, extreme sharpness, or smoother bokeh. Tom personally suggests that you get both.

For Nikon 50mm f/1.4D owner, the upgrade will help boost sharpness and faster in auto focus especially if you use older or smaller Nikon cameras (D70, D80, D60, D40).
