Comparison of primes on M6II and R, and general comparison of M6II with R

Let's face it:

The 85mm f/2.0 IS stm could be sharper (I should peep some pixels on this), yes it's stabilized which you will never get on M, and yes it has a half way macro thing, however,,,,,,

the overall look of the Sigma 56mm f/1.4 is simply better. The RF 85mm is not as bad as the RF 50mm, but it's backgrounds do draw attention more than they should.

Sometimes I think i should replace the RF 85mm f/2.0 with the EF f/1.4 IS USM L. Yes, that one is 950 grams in stead of 500, however, it's still 690 grams less than the 105mm Art. The L has some fringing, but if you shoot it at f/2.0 most of the time that fringing will likely be gone anyway. Or maybe save up for the RF 50mm f/1.2 L and just forget about that whole 85mm focal length. Or just sell the RF 85mm f/2.0 IS stm and use the 50mm f/1.4 Art in stead.

The RF 85mm f/2.0 IS stm is usable when you don't have demanding backgrounds. It's also usable for half way macro shots, and for landscapes. But it isn't a true macro lens, a a true macro lens should handle busy backgrounds better than this lens does.

Maybe it's all my fault for getting that 105mm first and waiting for a more compact option next to it after that, but when I see those 56mm handling this background way more pleasing I think the RF 85mm is a bit disappointing here.

I’m with you on this.

If I needed an 85 to put food on the table I’d just get the RF 85 f/1.2L, but now I’d rather put the big bucks elsewhere (like into the upcoming RF 100L Macro). And there’s no indoor sports going on around here yet, so I haven’t been able to test out my RF 85 f/2’s autofocus properly. The IQ is certainly good enough for that application (esp when matched up with FF). But if the RF 85 f/2’s AF can’t cut it, then like you, the EF 85 f/1.4L is waiting in the wings.

That’ll solve my FF needs. However for crop, the Sigma 56 f/1.4 is about perfect on my M6ii. Fast enough AF for sports, with very very good IQ, and nice bokeh (as has been demonstrated). I’m very happy with it when I need that focal length on crop.
