Originally posted by robw Really? I've taken over 3,000 shots of mainly flowers with it on my K20D and wide open to get that sweet bokeh and can't remember more than MAYBE 20-30 with CA issues. I personally have to believe it is my unfamiliarity with a new camera (my number one suspicion), an issue with settings or a broken camera or a true bug!
But thanks for the suggestion. I continue to investigate and have asked a couple of Pentax pros to weigh in as well. I'll keep the forum advised on what I find out as soon as I get a solution. I suspect it MAY wind up being "pilot error" though! *o)

How many of those flowers were against a white sky? I don't think this is a bug but a function of the photo. There are ways to avoid it as well as fix it. I can make every lens on my list do this. The main key is you have to have the WB properly set and get the exposure right. In your sample photo type, that can be difficult of course but those two items will help reduce it.
That said, it is entirely possible that the K5 is a little more susceptible to it. I have not tried my DA35 on that camera yet. It's dark now so for me to offer any sort of compare, It's going to have to wait.
This is a photo taken of a lens I have in the marketplace. It was taken with the FA31 and is over exposed. That's what I mean by you need to get the exposure right. In this case, I did it on purpose to show the inside of the rear of the lens.
