PMA: Sigma Shows Off with 3 New Lenses
A couple of days ago, at PMA show, Sigma presented 2 entry level lenses both with OS (optical stabilization) and one ultra-wide lens.
Sigma 10-20mm f/3.5 EX DC HSM
It seams that Sigma improved the popular ultra-wide lens 10-20mm f/4-5.6 EX DC HSM made for APS-C/DX sensors (Non Full Frame), making the new version with fixed a aperture of f/3.5 through the focal range. It also has two Super-Low Dispersion and two Extraordinary-Low Dispersion glass elements for the correction of chromatic aberrations. It will be available with mounts for Canon, Nikon, Sigma, Sony and Pentax DSLRs. Hopefully this will at leas as good as it predecessor, we will see some future reviews, I would like an ultra wide lens for my cropped sensor 40D.
Sigma 18-50mm f/2.8-4.5 DC OS HSM
Sigma also has released a standard zoom lens featuring an optical stabilizer and a wide aperture at it’s shortest focal length. This is also having two Super-Low Dispersion glass elements for the correction of chromatic aberrations. As the previous lens it has a Hyper Sonic Motor (HSM) for fast and silent focusing. Sigma also states that its OS it would work on Sony and Pentax bodies with in-body stabilization systems. This also will be available with mounts for Canon, Nikon, Sigma, Sony and Pentax DSLRs. Bottom line this is a good lens to replace the kit lenses, because this is faster.
Sigma 50-200mm f/4-5.6 DC OS HSM
Sigma also talked about it’s telephoto zoom lens. This lens has the same image stabilization as the 18-50mm f/2.8-4.5 and also has the Hyper Sonic Motor. Something to note, due to fact that is a low-budget lens, is the fact that it has internal focusing with a non-rotating front element. Also the lens is treated for correction of chromatic aberrations.
