Eager to try some of my R glass on the a7r5, but with a few weeks before my next stop in the ant farm, I was very grateful that the better half didn’t mind bringing the 28-90mm when she joined me here yesterday.
After a good bit of time outdoors today, even in very gloomy weather, I fear it has opened Pandora’s box.
With the highest resolution sensor it’s seen so far, it was not only up to the task. It produced the best, sharpest images across the frame, that I’ve ever seen from it. It very quickly got me to thinking about the SL3, which has the same sensor, plus some Leica features Sony doesn’t have.
The lens was great on the SL2 when I first shot it last spring right after acquiring it in Porto. It then sat in the dry cabinet while I wasted time shot with primes for most of the rest of the year. But this sensor seems to get just a bit more oomph out of the lens, perhaps for no other reason that the color profile is applied in raw files, which the SL2 doesn’t do.
Who knows . . . with a few weeks to go I’ll probably change my mind a few more times, maybe even come up with a wilder notion or two. But the lens (and the other R glass) deserves a body that has its profiles and which can exploit the capabilities of the R-L adapter with ROM lenses. And there are only two such bodies I can think of . . .
