Is the pre-shooting feature electronic shutter only? Or can mechanical be used with that mode?

Electronic acording to TFM.

It's e-shutter only, but it would be totally possible for Canon to allow it to switch to mechanical after the full shutter press; they have simply not decided to allow it. That option would be the best way to implement it, IMO.

Good thinking, at least an option of ES or MS once the shutter is pushed fully.

Of course the FPS will be limited to 15 FPS for MS after the button full push.

I suspect that may be why that feature was not provided.

Here is Bryan at TDP comparing image quality between the R5 & rf 600mm f4 + 1.4x versus the R7 & rf 600mm f4.

Don't tell your R5 friends, lest you subject yourself to their doubt & venom...

The elephant in the room that almost everyone ignores when comparing cameras with very different pixel densities is that if you go after "pixels on subject", the TC option takes away some AF sensitivity, AF speed, global contrast (even if little). You really need to match your larger-sensor, larger pixel camera with a longer and larger-pupil main lens to do better in every expected way. I remember when people were talking about how some FF DSLRs a few years back had multiple f/8 AF points when the 7D2 only had one, in the center, but trying to get the 7D2's pixels-on-subject with TCs on those cameras you might get f/8 when the 7D2 could operate at f/5.6 at ALL AF points. And if you put a 2x on an f/5.6 lens on a FF DSLR, there would be no AF at all, even with taped contacts, while the 7D2 with a 1.4x would still have one AF point that works.

Of course, if your subject is approachable and you can get 1.4x as close to it with the R5 and no TC, that option will give the best results if you're after background blur and low noise, and the subject's DOF is not too shallow. There is no substitute for real "reach".

R7 has AF with 2x teleconverter, I didn't realize that and tested it

ML doesn't have the f/8 limit. That's why Canon sells cheap f/11 lenses for it. I think it was mentioned in one of these threads that it can AF at very small apertures.

I like the preshooting (burst) mode, only wish it could be added to one of the Custom settings it takes a few button pushes to enable it, makes it slow to setup

Yes, because of the dual-pixel focus on the sensor. When I use a 1.4x teleconverter on my 7D2 with a 500 mm lens, I use live-view and it focuses very well even in surprisingly low light. I'm essentially using the 7D2 as a mirrorless camera, although the screen isn't as convenient as the viewfinder.

Ya, very interesting. The R7 has that reach advantage. I think the conclusion is in line with what we have been thinking, but it is good to see Bryan's test results.

Some people attach a loupe to the LCD and use it like a VF.

Interesting idea- something for me to try.
