I'm considering getting a 1.4 converter for my Canon 400mm f5.6 which will go on a 7D Mk II. Can anyone please advise the differences between the Mark 1, 2 & 3 versions that I may need to be aware of.
I may be replacing the 400 with a 100-400 mark II next year. Any comments on whether this zoom works well with the converter would also be appreciated
TIA
