Originally posted by paulh Some car show shots from October with the SMC-A35/2.8 on *ist D. Here's a question for you optics gurus. Check out the strange blue flares on the 2nd shot of the '56 Chevy bumper. It appears in a few other shots from that outing. I've never seen this type of flare from this lens, although I don't think I've used it in this situation involving bright highlights before. Shot in RAW and processed in RawTherapee - and at iso800 (inadvertently). Ideas?
I'd guess that effect is caused by the gross local over-exposure caused by the sun's reflection in the chrome. It's probably not so much a case of "
what caused it?" but "
how did the coating on an old lens cope so well?" I bet inspection of the RAW original would show extreme localised clipping in these hot-spots
