Three nice frosty shots Jim but .... do try them again with the Sigma - either will do. With Winter in full force early this year - I am sure you will get plenty of opportunities for doing this. One point is that these close-ups do not seem to be quite as sharp as your usual work. Check out a few with Sigma I did some time ago in Mancunia - in truth they are not 100% as sharp as expected as were taken on the SD14 before I discovered (and corrected) the back focus problem. http://www.pbase.com/zps/image/108165186 is first - just click Next for others
