Re: Switching back to R5... help needed

So you have  EF 400mm f2.8L IS 1st gen ? Does it really slows down to 6-9 fps on mechanical shutter but you can use ES to get close to 20fps without noticeable rolling shutter?
How can you describe the usage of sigma 150-600? af speed, accuracy etc?
I've tested R5 + 100-400 EF mk2 + tc1.4 and to be honest it was terrible for me - lot of hunting, quite slow AF - definitely below the standards. Bare lens without TC worked great. TC paired with 600/4 mk2 worked also great.
