Do you think there is a problem with using F/22 for 35mm??
Yes, I think using f22 for ANYTHING except 4X5-8X10 is a problem - most especially diffraction.......maybe, if you were desperate for DOF at very close up on 35mm - less so.
I mean, are you really looking for DOF of the Moon @ infinity ?? .....otherwise, why punish yourself with 1/80 SS and/or a higher ISO ??

I treated myself to a R andR7 body this spring. The attached photo was shot two nights after the Super moon from my deck using the R7 body with my 100 - 400 mm EF lens. I processed it with Photoshop Elements including a final touch with DeNoise plug in. This was shot from my deck handheld. Shot at ISO 800, 1/80th, f22.
Beautiful. 🌝🌝🌝🌝🌝, but how did the letters get up there

f22 is definitely not the sweet spot for the 100-400L due to diffraction. f8 to f11 is the sweet spot according to my experience as well as the MTF curves. I wonder if that is the cause for the massive chromatic aberration in this example.

The solution as you have already mention is high shutter speeds. The IBIS coupled with the IS of the lens will produce good results but shutter speed is always important when shooting moving objects with a long lens. I shoot with a Canon R5 and a 600mm lens and have no problem with blur but I am always aware of shutter speed. When shooting stationary objects I can shoot that 600mm lens with good results at slow shutter speeds, something like 1/100th as long as I am steady when holding the camera.

Lots of good commentary. I use High Speed Continuous, not High speed Continuous +, to stay with 15 frames a second to avoid rolling shutter. With the RF 100-500 and shutter priority at 1/2000 sec in sunlight and 1/1600 with overcast and auto ISO I get tack sharp pictures when the auto focus locks on correctly. I have more challenges with the electronic shutter (time delays) and setting up the auto focus settings (refusing to lock onto subject). But that is a different conversation. I've also used the EF 100-400 MKII with EF to RF adapter and get great results.

I'm very interested in hearing the responses. I am considering switching from my 90D to an R7!

Do it! Based on my experience in moving from the MKDIV to the R5 you will not be disappointed.

Better AF and speed.
Also if you come across a good deal on a vintage FD, FL or R lens the R7 uses them very well with an adapter.
Also ALL your EF lenses work perfectly with the R7. Once you use it you will not pickup your D90 again.
I kept my 7D but have yet to find a reason to use it over the greater versatility of the R7.
You can also get AF with teleconverters and small aperture lenses including eye AF and tracking.

How much VF lag is there for BIF using the mechanical shutter ?? Also, from what I can tell, the R7 mechanical shutter is very noisy - more so than the 80/90D ....

And?
I have absolutely no interest in BIF, bores me, so your point?

My point is the R7 is not necessarily for bird/wildlife people - so everyone has to qualify their comments. The R7 was supposed to be for birds/wildlife - this was supposedly the MAIN reason for Canon making it and for most people buying it !
Right now I am favoring the 90D over the R7/10 - I am currently using 80D in Canon. I do want 10 FPS but I must also have tracking ability for fast moving subjects - which is the main reason for 10FPS !

The focus systems on the new R series cameras are much improved over their DSLRs, especially their tracking capabilities. I have not done much research on the R7 as I am completely happy with my full frame for any situation including birding, much improved over my MKIV.

I am NOT talking about focus but refresh rate on the EVF - keeping the subject centered in the VF - because if you don't keep it in the VF it does'nt matter where the focus is !

There is NO issue keeping the subject more or less centered.
It is far more the ability of the user to keep the subject where they want in a frame from shooting cars moving at high speed and aircraft.
Both move exponentially faster than a bird.
