OK - this will probably astonish many, it is probably known in parts by most, but I haven´t seen this yet put into such a nice, stringent and logical explanation in one run. I am sure this should be posted to all the sections of GetDPI mostly for the smaller sensor cameras, but I post it to Sony now. Maybe the admins put it somewhere to keep as a basic point of start and information.
Watch it ! It is really worth doing. I definitely knew everything in this video, but even I was astonished as of the connection to the advertisements and the actual amount of cheating. I was not "aware" of this......
And finally: of course this works the same the other way upwards to medium format lenses with their bigger lens diameters. The exit pupil´s size defines the brightness of the image. And now you know why we at Hartblei use MF Zeiss glass for 35mm Lenses with very nice results. :angel:
