Canon R5 and Canon EF 500 F/4L IS Mark 1 FPS

[Joel Eade]

Thank you Joel and Brant so much for your replies.


Joel, could you please test your R5 with your son’s 500 f/4 IS Mark I when you get a chance? I just want to know what the speed of the mechanical shutter is when shooting with a grip and two genuine R5 batteries.


I plan to have the genuine Canon battery grip and all new R5 batteries. I also plan to use the ES more to take advantage of the 20 FPS, but would like to use the MS when situations call for. I’ll be happy with 8 FPS but 5/6 is too slow. Please let me know, thank you so much!

My son brought his EF 500mm f/4L Version I to my house today.

Even with the battery grip and 2 fully charged new R5 batteries it will not support the H+ mode at 12 fps. With the mechanical shutter I estimate that it is shooting around 6-7 frames per second.

I held the shutter for a count of 3 seconds and counted the images. I repeated this test 3 times. First time I got 19 images, second time I got 20 and third time 21.

The electronic shutter is still functioning at 20 frames per second as best I can tell by using the same method as above.

After testing it I looked in the manual and the Version I 500mm is not listed in the chart of lenses that will support 12 frames per second.

The slower rate is fine for perched birds or swimming ducks and the electronic shutter would be the ticket for flight shots.
