R7 from my car ?! What the heck ?!?!

100% electronic shutter with a slow read speed for the R7 seems explanatory enough without any pictures attached showing what constitutes terrible.

What I don’t get is why people post questions like this without at least testing like shooting conditions first to determine if that might be the issue. Switch to mechanical shutter on the R7 and see if it’s better. Or at least EFCS if trying to avoid shutter shock

Impo, the R7 is practically useless in Mechanical Shutter mode. I’ve heard a few people say it imparts some amount of shutter shake at practically ALL shutter speeds, and in my brief trial of MS, that seems to be true. If I need to shoot something with MS, I’ll use my R5.

I’ve shot thousands of shots in EFCS (why would you use full mechanical?) with my R7, and not a single one had any trace of shutter shock.-

For this scenario (I'm not clear exactly what it is but can guess) what advantages exist for Mechanical and what negatives are there for ECFS.

The only negative I’ve ever heard about for EFCS is the possibility of cut-off bokeh with very wide apertures (F1.8 or faster) at very fast shutter speeds. I presume that the OP was shooting birds from a car with a lens slower than F1.8, so this wouldn’t apply here.

As it happens I often shoot Mechanical on the R5 but that may purely be to have feedback the shot was taken at the moment of button press (noise).

EFCS gives the same feedback. It’s e-shutter that doesn’t make a noise (unless you set the camera to give you a noise, which you can do with the latest Canons).

Thanks Alistair. With the R5 mechanical gives me a more noticeable noise and ECFS feels like it's very damped.

That's said I will spend this week using ECFS only to see if my brain is happy with the new (noise)

I couldn't remember writing this but I think the R5 (and other Rf cameras) keeps with the higher 14 bit colour bit depth. Is that correct?

I'm pretty sure that's correct. I have never read anything about bit depth dropping with EFCS.

I think we still have 1/8000th available in first curtain (not sure if the R3 is faster still).

Yes, that's right. I think the only way to get a faster shutter with any R camera (including the R3) is in e-shutter. The R6II allows 1/16,000 in e-shutter, but only in Tv or M (I think). I can also get 1/16,000 in e-shutter on my M6II, which only has 1/4000 in mechanical.

I did find this which has some evidential commentary.

So, to keep my 14 bits, reduce shutter shake but learn to enjoy the dull noise I will benefit by using ECFS.

I think so. Report back on how it goes.
