Quote:What are "source images"?
Sounds like a nice lens on a troubled camera. I start likeing leaf-shutters again. Is anyone still using them in a interchangable lens system? In the film days most medium format cameras had them. As far as I am aware, right now there are only fixed lens cameras (e.g. Fuji X100(s), Ricoh GR, Coolpix A and RX-1) with leaf shutters, that I would call serious.
source images = test chart images used for the MTF analysis in Imatest.
The best shutter is, of course, no shutter at all. :-) Like in the Pana GM1 or GH3 - at least when selecting the electronic shutter.
