of course there is light loss in a lens, we just don't see it there because this testing is apparently done on camera jpegs that have corrections applied... it's the only explanation for zero light loss.
the real question is, if pentax corrected it's lens vignetting in-camera, why is the sony showing so much vignetting... did they simply correct it less than pentax did? the sony 35/2.8 does have significant vignetting, and there is evidence that the correction is written to the raw as well.

DSLR sales over the last few years have lost Olympus and Sony completely as they are both now entirely Mirror-less.
the only reason that dvd sales dropped was because of new technology that competes with it... i was in the dvd creation business for years, i know all about it... everything is online now.
sony is still selling dslrs, that use a-mount lenses, that can be mounted on sony mirrorless cameras with the lea4... you get pdaf with that adapter, it has a mirror in it.
it's not as sophisticated as the k-3 autofocus system.

Originally posted by Rimfiredude I have never seen or handled an NX1, but from what I read, it is quite the camera. But I don't think that is the Mirrorless Camera most of the people in this thread are talking about. It is the one you hold out in front of you and wobble and weave around while you are trying to get a good, steady shot. It's like trying to get a good picture with your cell phone. Just my opinion.
we are referring to mirrorless cameras that have evf displays, so they are handled just like dslrs with an ovf... you put your eye up to the viewfinder.
shoot only with the viewfinder, except maybe when you want to tilt the rear lcd display for a ground or overhead shot.
