So, the camera I am eyeing off has a KA2F mount, and compatable with KA and KA2. Although there are probably 1000's of opinions about various makes and models, my main concern is am I going to get decent quality glass in comparison to other systems?? I know Pentax make great lenses with good coatings, but how do they stack up against other manufacturers?? I have used Pentax lenses on this camera, but to be honest, my eye is not keen enough to notice any differences. I'll probably only go for 2 lenses at this stage. maybe a 12-24mm and an 18-250 or there abouts to cover most situations. Cheers.
