The Well build Sigma 10-20mm F3.5 EX DC HSM is a relatively fast wide-angle zoom designed exclusively for APS-C format Digital SLRs, covering an effective focal range of 15-30mm. This lens squeezes a relatively fast F3.5 constant maximum aperture. The lens has a minimum focus distance of 24 cm (9.4 inches) throughout the zoom range, and features two Super-Low Dispersion glass and two Extraordinary-Low Dispersion glass elements for the correction of chromatic aberrations.
At 10mm, this lens gave mixed resolution results, but showed it is capable of producing images with very good sharpness across the image area. At f/3.5, the centre resolution is already very good and the edges of the frame acceptable. Stopping down appears to reduce the resolution in the centre very slightly, although the sharpness towards the edges improves.
In the middle of the zoom, at 14mm, the resolution characteristic of this optic changes somewhat, with the centre resolution reducing somewhat. However, the centre resolution is still good between apertures of f/3.5 and f/16, with the best quality across the frame being achieved at f/11 again.
And finally, at 20mm, the lens appears to be at its best at this focal length with the centre resolution approaching excellent levels. The highest resolution across the frame is still achieved at f/11, which means this aperture can be set knowing that the highest resolution will be achieved no matter what the zoom setting is.
Preferably Cash of Collection in Zurich but can be shipped within Switzerland .
