Originally posted by repaap Funny, my friend who has a lot of recent as well as some older canon, like En osaa sanoa 5D IV and also crop 7II said that he has -zero- interest of buying any of these new ones from canon. He is enthusiast in bird shooting and has also 100-400 zoom and many other fine lenses. Not so sure if that many will actually go there just like that. Understandable to go with some Ed lenses, hard to see the point with adapter which does not really work that well. Suppose that many things works quite well with EF lenses if one has proper canon made adapter. But that class leading stabilisation will be that good only with RF lenses. As well as focusing at it’s max speed.
Well,Ive not ever owned a Canon Dslr so i cant judge apart from brief use of a Rebel my daughter owns.They seem ok to me.
The stabilisation without the RF lenses will still be 5 axis plus the digital stabe which plenty have said is class leading.The RP and R models rely on that plus lens stabe,theres no problem at all.
If your friend has mk 2 100-400 he has the best 100-400 that exists from every comparison report Ive seen(lots).It even outdoes the Tamron/Sigma 150-600s when fitted with the 1.4x TC.
All in the RF mount that use EF glass comment about the increased performance over the Dslr standard,your friend should rent or borrow one of these new bodies.He may be surprised!
