The Sigma 10-20mm f/3.5 EX DC HSM is available with lens mounts for Sigma, Canon, Nikon, Pentax and Sony DSLRs, and provides a 15-30mm focal range. The lens features 13 elements in nine groups with one SLD (Special Low Dispersion) and two ELD (Extraordinary Low Dispersion) glass elements designed to...
Love the effects with short depth of field. Nice lens for landscapes. Not experienced enough photographer to quote on lens creep or vignetting but for an amateur like me, a lovely wide lens for my entry Nikon D3100, producing very good pics.
Consistent Output; Easily Interchangeable; Lightweight; Quick Focus; Strong Construction
With a brighter f/3.5 aperture, the new Sigma 10-20mm lens will be better for low-light photographers. Priced at £440, does the new lens warrant the price tag?
Very good resolution; Good build quality; Excellent value; Low levels of Chromatic Aberrations
82mm filter size; Stiff manual focus ring
The well-built Sigma 10-20mm f/3.5 EX DC HSM Lens, at review time, is one of only a few lenses in the ultra-wide angle APS-C lens class to have a fixed maximum aperture. While f/3.5 is not what I typically consider wide/fast, the fixed maximum aperture allows a constant wide open aperture exposure...
Sigma's widest nonfisheye and fastest ultrawide zoom, the constant-aperture 10-20mm f/3.5 belongs to the EX family of sturdily built, optically gifted Sigmas. To control multiple forms of aberration, it uses three low-dispersion glass elements and four aspheric elements-the most of any Sigma.
I bought it instead of Sigma 10-20/4.5-5.6 with good discount price. For such price very good wide zoom lens for crop cameras. When buy try to check a few copied due bad Sigma quality control. My copy is really perfect. For higher price check Tokina 11-16/2.8, but for me zoom range is not enough
Fast and accurate focus; Sharp in center even open at 3.5 at 10 mm; Very reasonable sharpness in corners after 7.1; Overall picture quality better compared to Sigma 10-20/4.5-5.6 and Sony 11-18/4.5-5.6
Some CA at 3.5 in corners; No after 4.5; Could be less distortion in corners at 10-12 mm
I bought this lens specifically over the Sigma 8-16 because I needed it to accept 80A filters and have a constant f3.5 aperture because I do a lot of both low light handheld and tripod night shooting.
constant f3.5; accepts filters
though the center is sharp at all focal lengths and apertures it is almost useless at 10-12mm due to poor edge sharpness and very high lateral color starting about 30% out from the center
Released earlier this year, the Sigma 10-20mm f/3.5 EX DC HSM is a mouthful to say but a true pleasure to work with. I begrudgingly write this review because it means I have to send the test lens back to Sigma…. …and I really don't want to!
This is a great quality performing lens. I have had the Sigma 10-20mm 3.5 for 5 years and I cannot fault it.
