  • yeah yeah, I know. I meant to say that with extender the lens slows down in F-ratio. Stopping down was not the right phrase to use.
  • Ok, so for the RF600 and RF800 the AF area with and without the extenders stays the same.
  • Curious to know too for the RF600 and RF800 although stopping down even further will make it probably useless in many situations like BIF. I can not test only having EF extenders.
  • Nice experiment. Maybe in low light situations the R5 perimeter focusing for some reason is less reliable in combination with a F/11 lens and Canon want to prevent having troubles there. An example ...
  • Thanks for the links. I was aware of the min focusing distance but somehow the limited focussing box of the RF600 (on R5) escaped from my attention. Yes, I have experience with focus limitations ...
  • Replied in in perspective
    Yes, good to mention this. The R5 AF is a big step forwards compared to a DSLR to every aspect. Although I have to say that my 7D MkII has a better horizontal spread of AF points compared to the ...
  • Beautiful shots! Very inspiring. I own the lens for only a few weeks and looking forward to my first trip with it to France soon (living in The Netherlands). The EF600 will not join the party ...
  • One would think if focussing on centre pixels is possible at native F/11 why not on outer pixels that ‘see‘ the same F/11. Those pixels aren’t any different are they? I wonder what would make it ...
  • Thanks for sharing your view on it and your interpretation of my motivations. For sure I did not dig very deep into the specs of it but also for sure the limited AF area is not one of the first ...
  • Created discussion thread limited AF area R5 + RF600mm F/11
    Having both RF 600mm F/11 and EF 600mm F/4L II lenses it is surprising and disappointing to see that the max AF area of the RF lens is much smaller than the almost full sensor AF area when the EF ...
  • Replied in butterfly
    one of my first macro shots with the new R5, hand-held love the details
  • Thanks for your insights and sharing your experiences in the field. It is reassuring that you experienced no problems whatsoever despite the rough treatment. The rattle sound of my RF 600mm is ...
  • Thanks, very helpful. Wonder if Canon in the mean time has made some kind of statement what has been changed in the IS design for RF lenses making parking of the IS element(s) superfluous. I am ...
  • Created discussion thread RF 600mm F/11, RF 800mm F/11, IS-rattle
    Got the RF 600mm F/11 on my R5 recently with hiking/birding in mind. It is compact, light weighted and the optical performance impresses me. But there is one thing that bothers me. Yesterday during ...
