I meant problems with ANY legacy lens, probs similar to the issues that the Nex 7 has... but not the Nex 5n...with the wide angle rangefinder lenses. I admit, when I checked for adapter availability, I saw an M mount adapter for NX, but didn't realize you had to trim plastic etc. and then replace the lens mount! I have numerous SLR lenses, but nothing extreme, just 24 to 300mm, and I almost always use my old MF lenses on my 5n. Can I assume image quality will be equal to or superior to that obtained with a NEX 5n? I would like to be able to crop a little more sometimes and would consider the NEX 7, except it's just outside my price range. Not sufficiently patient to wait for a FF NEX and wary of RAW processing for Fuji X cams. Would the NX be an upgrade from the 5n? Hadn't really considered the Samsung until the NX300 was announced.
