I have tried this lens for one shooting event (indoor) on the *ist D.
I found it brilliantly sharp and haven't noticed any CA-problems.

Three different people have sent me a bunch of RAW files from the FA

24mm f/2AL [IF] that exhibited quite a lot of CA. You see it as color  
fringes around elements in a scene, particularly at the edges.

Paul Stenquist sent me several images comparing the A24/2.8 and the  
FA*24/2. The A24 was much better wide open, and at most other apertures.

I don't expect a zoom to perform as well as a prime. That said, in  
comparison with my A24/2.8, the FA20-35 produces results that are  
almost indistinguishable.

Now, I have mentioned this before: I'm still perplexed by this FA*24  
lens. Several people have told me that they just can't abide with it,  
and several others purport that it is a fabulous lens. I can only say  
that I've avoided it because of the extreme range of opinions I've  
discovered about it. I'm satisfied with both the A24/2.8 and the  
FA20-35 ... both return very good, very sharp, very low CA results.  
At least mine do.

I shoot exclusively with the digital bodies, and the images I've seen  
from the FA*24 were all taken with the *ist D/DS bodies. I have no  
idea how this lens performs on film; it's not relevant to my uses for  
it.

I don't have an FA24 or an FA*24. There seems to be some discrepancy  
in the way this lens is listed in various place. I have the Pentax-A  
24mm f/2.8.

That's really all I have to say about it.
