So you’re saying that used mk3 EF 600mm f/4’s are selling for half price? Certainly not that I’ve seen. Used mk3’s seem as rare as hen’s teeth. Now, mk2’s yes they have gotten very affordable but then there are more differences than AF speed between that and the new models.

Only real difference is the size and weight, aside from that you'll be getting the same resulting image, I don't see a point to paying $13,500 for a RF 600 f4 when you can get a used EF 600 f4 MK2 for $7000.

But do what you want to, if weight is worth over $6,000 to you, that's fine.

We don't know that it is just weight; the RF AF and stability may be better. Without some more comparative facts, we can't tell what the extra $6K buys you (besides new-ness and lower weight).

Link Taken from another thread... looks like the extra 6K will buy a fuzzier picture too with 1.4 tc:

I'm oddly not surprised, I'm not switching my EF 500 f4 for awhile...

That one is a keeper.  Best lens I ever shot with.
