Sigma UK Press Release
Super wide-angle zoom lens designed exclusively for digital SLR cameras
- Compact and lightweight ultra wide-angle zoom lens
- Covering an extensive angle of view of 102.4° to 63.8°
- Three Special Low Dispersion (SLD) elements and three aspherical lenses produce top quality optical performance by controlling aberrations
- Inner focusing system ensures the length of the lens remains unchanged whilst focusing
- HSM (Hyper Sonic Motor) system complete with full time manual focus override
- Minimum focusing distance of 24cm (9.4”) at all focal lengths
The Sigma Corporation is pleased to announce the launch of the new 10-20mm F4-5.6 EX DC HSM lens.
The super wide-angle capability of the 10-20mm zoom makes it a very powerful tool for both indoor and landscape photography. It is specifically designed to optimise results with digital SLR cameras encorporating APS-C size image sensors.
The wide angle of view (102.4°at 10mm) with broader perspective, offers the photographer greater freedom of expression.
Three SLD glass elements are employed for effective compensation of colour aberration, a common problem with super-wide angle lenses. One molded glass element and two hybrid aspherical lenses, offer excellent correction for distortion, as well as all types of aberration.
This lens is equipped with an inner focusing system and HSM design providing quiet, high speed autofocus while offering full time manual focusing. It has a minimum focusing distance of 24cm (9.4”) at all focal lengths. The non-rotating lens barrel is eminently suitable for the petal shaped lens hood (included) and circular polarizing filters.

Exciting to see that we, the 10D user slowly get our wide-angle solutions. Unfortunately, like the 12-24 from sigma, the lens is rather slow (up to 5.6).
There ist also the upcoming Tokina (12-24/4), the I think coming Tamron (11-18) and the old and big slow 12-24 sigma.

I have a Nikkor 12-24 f4 and I'm more than happy with it, but I would like it to be a 10-24 or at least a 10-20 like this from Sigma. On a Nikon DSLR (DX sensor) the Nikkor is like a 18-36 on film (1.5x factor) and the Sigma like a 15-30. Not a big difference, but I love that 15mm wide angle.
What I don't like from this Sigma lens is the variable aperture, specially when I use my 14 years old Nikon Speedlight SB-24 flash where I must change aperture manually (with modern DSLRs it only works on automatic -no TTL- and manual modes), so I have to take care of the aperture when zooming.

I use the Canon 17-40mm, which on the 10D isn't really that wide :( I quite like the look of the Tamron 10-20mm lens myself - I have the 28-75mm Di lens and it's very good.

Going for a wide angle lens I compared the TOKINA 12-24/4 to this lens.
The TOKINA gets rave review the SIGMA not yet. Any pros and cons ?

To be fair, the Sigma hasn't been reviewed at all yet :) I don't even think it has started shipping. You might also want to consider the Tamron 11-18mm lens.

Mark, do you know if they are going to market a FourThirds version of this lens? Could be a cheaper alternative to the Zuiko Digital 11-22mm f/2.8-3.5 super-wideangle zoom that has been around for some time.

Sorry, I have no idea if Sigma will release a FourThirds version, although it would certainly make sense!
