Originally posted by WMBP Anyone with experience able to help me compare the Pentax FA 35 f/2 (the older, less expensive non-macro Pentax 35mm) with the Sigma 28 EX DG f/1.8 macro? Both seem to sell for about $300 and both look like very good lenses for the price. I like the Sigma's focal length a little better - 28mm (42mm-e) is closer to what I want - the 35mm is a tad long. (A 26mm would be even better but doesn't seem to exist.)
Hi,
I have the Sigma 24mm f/1.8, which is I believe the same size as the 28mm, as well as the Pentax FA35. And I've read that the Sigma 24 and the 28 are similar in other ways as well, but I can't say from first hand experience. So this is only sort of relevant to your question.
I think the FA35 is a terrific lens, world class. I think the same of the Sigma 24. No complaints whatsoever re image quality, rendering, etc.
However, I don't use the 24 nearly as much as the 35, simply because the Sigma 24 is a big, clumsy hunk of glass. It's at least 2x the size of the 35, maybe 2.5 or 3x. Obviously, this sort of thing matters to some people but not others.
Also, I find the Sigma's build quality unsatisfying. For some reason, the plastick-y FA35 feels more solidly built to me. (BTW - I also have the Sigma 18-50 macro f/2.8, like you, and the Sigma 24 doesn't feel as solid as the 18-50. But I agree with you that the 18-50 is just 'pretty good,' not stellar. Very useful, nonetheless, and 'good enough' for most occasions).
Good luck.
