Sigma 15-30mm f3.5-4.5 EX Aspherical DG DF

Review Date: Mar 16, 2007 Recommend? yes | Price paid: Not Indicated | Rating: 9 

Pros: Good build quality, sharpness,accurate focus.
Heavy and big, not for those with weak forearms.

Bought my copy well used off ebay. The optics on this lens are excellent but the front element is vulnerable as it is very bulbous. The lens is sharp wide open but to get the best from it should be stopped down to about f8 - f11. Quick and accurate focusing.

The colour is warm and to my liking and the bokeh is fine. This is my main walk about lens on my Kodak DCS620.

Sigma 10-20mm F4-5.6 EX DC HSM

Review Date: Mar 16, 2007 Recommend? yes | Price paid: $280.00 | Rating: 9 

Pros: Sharp, quick focusing,nice warm colouration.

I have been using this lens for several months now and it rarely leaves the front of my camera. Sharp at maximum apeture and ultra sharp by f8 - f11. It need careful use with images with staight lines close to the edge of the image as it will cause distortion. All in all an excellent lens for a budget price. (280 UK pounds)
