An RF 500 f5.6L would be fantastic for R users. But from Canon's point of view this is no good lens: a) It cannibalises sales of 500 f/4 and b) they cannot demand 10 grand for an f/5.6 of this focal length.There are Fuji patents pending for a 300 f4 and 500 f5.6. A 500 f5.6L IS on the EOS R5 would be very compelling.
A 50mm 1.8 does not need to be a nifty fifthty. I have the 50mm 1.8 s on Nikon and it is one of the best lenses I have used. Really solid IQ. Personally I think the 1.4s will come in when the line up is well filled out.The 50mm/1,2 is too heavy and expensive and the 50mm/1,8 is too poor. 50mm/1,4 is the perfect solution!
I've only been in this hobby for eight years, and the thing I have been waiting for that whole time is the elusive EF 50mm 1.2L that actually focuses and doesn''t have so many secondary problems. Given the clamor over those years for that lens I'm surprised that every second response here doesn't mention it. Maybe everyone lost hope so long ago that they no longer regard it as "possible."Canon needs a "great" 50mm 1.2L lens for the the EF mount. A companion to the 35mm 1.4L II, and a competitor to the Otus and sigma lenses of that approximate length and girth. The RF version I'm sure is fantastic, but it won't work on canon's cinema line, or any of it's professional cameras. The current EF 50 1.2 is fine for internet bokeh queens, but we need something with less field curvature, less longitudinal CA, and better detail wide open.
This is far too close to 70-200 f/2.8.Nor sure if anyone mentioned this, but my first choice would be a EF 50-200mm f/2.8L IS III USM. This would be my new goto lens. I expect there would be some barrel and pincushion distortion with it, but Canon DPP 4 could take care of that issue.
At this stage there are none 500/4 native RF mount lenses available so there is nothing to cannibalise yet with new market realities at full force, 500/5.6 may be a better placed lens. Yes it is a full stop slower glass. However with a host of Canon RF F7.1 zooms in the making, 500/5.6 - in my view - would be just fineAn RF 500 f5.6L would be fantastic for R users. But from Canon's point of view this is no good lens: a) It cannibalises sales of 500 f/4 and b) they cannot demand 10 grand for an f/5.6 of this focal length.
