Originally posted by Wolfeye Well, one issue for me is paying the same price for a lens that only goes to 2.4. With the crop sensor bodies I like to have as much DOF to play with and limit as possible. The other thing is that the Nikon has a built in motor and focuses fast even in low light. My Pentax isn't quite as good. Still, the image stabilization is quite nice, so in some cases I'd actually prefer the Pentax, especially where light is low and the subject is static, like a museum.
Have you thought about the Sigma 30mm f1.4? The newer art version seems to be pretty good and it would be faster.
From what I can see, the DA 35 f2.4 is about fifty dollars cheaper than the Nikon 35 f1.8, so there is a price break. I guess if you could find a used FA 35, that would be close too...
