Hi all,
I am new to the forum.
I have run into a strange problem with my 600mm mark 2. My high speed burst using 2 differant Canon 7d mk 2's has dropped in burst rate by about 50%. It is roughly now about 5 frames per second on both cameras where normal rate is 10 fps. I am a wildlife photographer and use high speed burst all the time. The only lens I have that this happens with is the 600. All the other lenses the burst rate is right up to snuff.
I cleaned the contacts, checked all the settings on the lens and the cameras. This did not help. This problem surfaced all of a sudden. Last week everything was fine. All other functions of the lens seem to be fine. I also put my 5d3 on it and the burst mode seems ok.
Thanks in advance everyone,
