I recently ordered my own copy through Amazon / 47th St Photo. I was very disappointed when the lens I got was way out of calibration with very soft center area focus at 28mm near infinity af F5.6 getting more out of focus as you approach the top right side of the lens. I have contacted 47th St Photo and they ...             Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens for Canon Digital SLR Cameras22 reviews SIGMA SIGMA, 2006 Great macro, excellent around f/6.8 This would be an awesome lens if it was 2.8 all the way and had IS. However, it would also be twice as big and cost 4x as much. For what it is, this lens is really good. Around f/6.7 it is very sharp. The distortion is noticeable at 17mm, though. Focus is fast and accurate, and the build quality is very good. The lens does extend on its own when carried pointing down, though. At 17mm f/2.8 it ...             Opteka 67mm High Definition Professional UV Protective Filter5 reviews Opteka Opteka thanks This filter saved my lens from breaking.

It is quite sharp (not scalpel sharp at 2.8, but good nonetheless), it focuses very close to your subject (2 inches?) and equally important: it covers a really good range, 17-70mm. It's wide enough for landscapes and close enough for portraits and performs very well in both situations. And it does makro. I use this lense as a walk around ...             Opteka 77mm White Balance Lens Cap Disk for Digital SLR Cameras Opteka Opteka The Opteka White Balance Lens Cap is great for use with digital cameras.
