I tried this lens on the OM-D and found the resolution and contrast very good. But it is harder than using these lenses on the NEX I admit. I tend not to use the magnify function on these cameras as it distracts me. I've got used to it now that I get perfect focus 95% of the time.
The next few posts I willl try to show you what is possible with these lenses. If you're willing to put the effort in the rewards can be very high. Most, if not all of these images, were taken wide open at f2 or thereabouts.
