Thanks for posting these David. They're better than the stars at the edge of the full frame image flat out at 14mm and f2.8 (unsurprisingly!), but I wonder how many stops you'd need to lose before they tightened up? Also, I can't sure why a prime lens would be be less sensitive? If anything, the rays from the outer edge of the rear lens element to the sensor would be more critical as the lens is shorter? (Not a great deal of thought put into that, first order thinking only!)
Still - a new front cover and lens mount for the QSI ain't exactly cheap. hmmm.
Thanks again for leading the way!
cheers,
Andrew.
