Very slight lateral CA on my test subject, visible in PS only with great enlargement. I probably wouldn't have noticed w/o enlargement. OTOH, I do find that sharpening for printing enhances CA.
A couple of months ago I shot the same subject with the Zenitar 16 mm. f2.8 fisheye, also mounted on the D. Comparative results: The $125 Zenitar is the sharper lens, and also shows very little CA. Unfortunately the Zenitar still has pronounced distortion on the D (where, of course, one is just using the center of the lens).
Conclusion: the DA 14 should provide what I need since it is useable wide open. I wish it had f2.0, but will work around that. (As I've posted before, I often use primes indoors in low light, and need them to be decent wide open.)
Okay, Pentax. Next priority is a DA 50-150 f4. (Alternatively, Sigma would please me by coming out with a 50-150 f2.8 that is as good as the EX 70-200 f2.8).
Then it must be a DA 18-20 f1.8-2.0. After that I'll be pretty well set.
Except for the FA 600 f4.
Not interested in the forthcoming DA Limited. Too slow, and I have good primes at 31, 50, and 77. And I'm exhausted from the wait for the DA 14.
