Summary for Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens ...- Terrific Value
Notes on Sigma 17-70mm f/2.8-4.5 DC IF Macro Lens ...- I recently got this lens for my Minolta 7D, but wish I had made the investment a long time ago! I'm always stepping back, stepping back, oops, my back is against the wall, trying to get more interior architecture in the frame. That is, until I got this lens! I have a 28-80 lens for a Minolta film 35mm camera that just isn't wide enough, epecially with the crop factor working against me. The versatility of the Sigma 17-70 now allows me to get everything I need in the frame and with very high quality -- plus the additional macro ability is something I didn't think I would use much, but have found the extreme close-up option really fun to experiment with. I don't see myself changing lenses much ever again!
