Hello, I have already seen some samples from DA 16-45 and it was very good experience. This lens is sharp loosing just a little in corners and has very good contrast. It is certainly better than FAJ 18-35 that I have been testing for a while. I am almost ready to buy it, but I'd like to ask one question to its users. Does DA 16-45 have rounded diaphragm like for instance FA 24-90 has? Diaphragm on most new Pentax lenses has rounded shape at open apertures (let's say 4.5, 5.6, 6.7 in case of this DA) and I just wanted to know if this lens share this feature too? TIA!
-- Best Regards Sylwek
