Canon EOS R5 Mark II deliveries have already started

I got my m2 today, the buffer size when shooting raw/jpg is about 66 shots, up from about 45 so a little bump in buffer. The shot buffer runs out in about 5 seconds give or take. definitely not high enough for serious sports shooting IMO but it is better overall.

What card are you using?
That, sadly is my biggest gripe with R5, it doesn’t matter what CFE-card I use, because it’s always and forever limited by my SD card. «No one» agreed with me when I said it when the specs leaked, but this is one issue I also see many of the YouTubers who has the camera and have tested it previously complains about. Shooting redundancy is often crucial .

And I want Canon to fix the behaviour when the buffer is full, I want a nice even cadence, limited by the card write speed. Not the "pause a few seconds, burst, pause a few seconds, burst". I run into this when I have 'too many' shots in a focus stack, I can get around that with CRAW and lower ISO, but it isn't ideal.
This may be something that falls into the category of 'it's not a bug, it's a feature' meaning there's nothing to fix. Canon's thought process may be that if you've selected a high frame rate to enable you to capture the peak of action, it's better to have bursts that still enable that rather than a slower but even cadence that results in the peak action being missed.

Couple of examples...shooting a bird in flight where you want the right part of the wingbeat, or shooting a tennis volley where you want the ball just leaving the racquet. The first situation happened to me a the weekend before last. It was actually the first time I've run into buffer filling on my R3, mainly because I was positioned where birds were passing by on a long, low flight path. The AF kept tracking the bird as I followed it, and with those short bursts after the buffer was full I was able to still get the extended/raised wings later in the flight path (which was often around the closest point of approach). With a slow cadence, I'd probably have missed those shots (odds would not have been in my favor at 5 fps vs. short bursts of 30 fps).

Still, the behavior could be modified to make it user-selectable. With Servo shooting, Canon lets you select focus priority, release priority or equal for the first shot, and for subsequent shots you can select focus priority, shooting speed priority or equal. In the same way, Canon could enable selection between frame rate priority and continued shooting priority.

Anyone else notice the buffer size dramatically drops with pre capture enabled? Mine goes from 62 to 19, which pretty significantly reduces the usefulness IMO
Yeah that sounds about right. The normal shooting buffer depth assumes that the camera can write files to the CFe card at a reasonable pace as you continue to shoot. The camera can't do that with pre-capture so it has to keep everything in RAM. That decreases the depth significantly.

I guess I could switch to craw and no jpeg to get more out of it. Annoying though- too bad they don’t give it as much ram as the 1 and even 3 series bodies. That’s one area where having a high res “flagship” would have been nice

Edit:
It’s plain raw that really destroys the buffer with precapture. With craw (with or without jpg) the buffer depth is 90 with precapture and 94 without. Compared to 62 vs 19

I think the R1 should be better at this even if it had the same amount of RAM just by virtue of the smaller files from the lower MP sensor.

I finally had time to sit down and go through the menu, They seem to have changed the AF tracking modes Where there were 4 options. There are only 2 options now. I hope to get to play around with the new tracking features soon to see how they behave but am apprehensive of trying it out in a live event where the pictures I am taking matter.

I did change the mode from raw/jpg to jpg/jpg and can get a much larger buffer that lasts for many seconds. I hate to give up raw but I think I can make the j/j buffer work for my sports shooting. It would have been nice to have more ram in this thing for that since ram is still dirt cheap.

Just use cRAW :)
