The A7/R with native lenses is still much smaller and lighter than a comparable FF DSLR setup, so I\'m beginning to think that native FE lenses may still be the best compromise between size and performance.
What could possibly be wrong with RF lenses at 50 or above on the A7r? For example, performance of the ZM 50 planar or 50 Summicron should be great and I\'d like to see what Zeiss comes up with that will beat a 90 Summicron on the A7r.
Well, Ron has mentioned that the 50 Summilux performs better at the periphery on the m240 compared to the A7, but, even if the full potential of those lenses is realized, the FE 55 looks to be the next step up, nearer to the 50/2 AA or OTUS.
I expect the 50 Cron to perform better than the 50 Lux wide open for obvious reasons and I think it\'s unlikely we\'ll see 1.4 aperture native FE lenses anyway.
You were commenting on the best compromise between size and performance. My point is that, although performance of wider RF lenses may be questionable, rangefinder lenses 50 mm and over may be the best combination of size and performance especially the F2 and smaller aperture RF lenses. Note, I\'m not saying the absolute performance will necessarily be better, but the RF lenses 50mm and over may be a better size/performance compromise (of course this assumes one doesn\'t want AF). And again, I think we\'ll be waiting a long time for the native FE lens that will outperform the 75 or 90 Crons on the A7r (pure speculation on my part).
