I mostly use the Sigma 10-20 f4-5.6 EX DC and the Pentax DA 18-135 f3.5- 5.6 WR. Both my lenses are excellent copies and tack sharp. Note: I get a combined seamless focal length from 10 to 135 mm (15 to 200 mm in APS-C term), covering my genre of Street, Travel, Architecture and Landscape Photography - 85% in of the time - 50/50 ratio. For that balance 15% low light situation shoots, I use the brutally sharp Tamron 28-75 f2.8 lens. And for that odd sports, wildlife, naval or air show shoot, I use the Sigma 70-300 DL Macro I purchased for a song from KEH - an excellent & sharp copy. Happy that I have covered all my bases including inclement weather shoots for cheap. Regards. Bipin - from that far away enchanting land
