Originally posted by eminker Would you recommend the Sigma 28 F1.8 over the Pentax F/FA 28mm F2.8? I thought the contrast was better with the Pentax lenses. Obviously, you do get an additional stop

I got the Sigma 28 as a close macro. I'd compare it with the FA 35mm Macro, not the FA28mm. If you want more of a general use, get the FA.
Contrast - that's an interesting thought. I don't use it much outdoors and in high contrast situations. I think I'll do some this weekend in the garden etc, see how it rolls. This means the weekend will be overcast and damp...
The 21mm is wonderful for contrast. I was honestly surprised when comparing similar images with the zoom. Plus, it performs really well wide-open indoors. As a bonus you get occasional looks from people. Now I can pull the 40mm out of my pocket and show them that, too!
