I have a few EF Lenses that I will probably keep because, for their intended uses, they work fine on my R5 and I have no compelling reason to get rid of them. However, in deciding whether to replace an EF lens with an RF equivalent, one should be aware of some of the features that are available with the RF lenses that are not available with an EF lenses.

Whether these "features" are important enough to warrant changing from EF to RF is of course a personal choice and would depend on how important these things are to your use cases.

1. Distance scale shows up on screen and in EVF while in manual focus (RF:yes, EF:no)

(Many EF lenses do have a distance scale on the lens whereas none of the RF lenses do)

2 . High Speed Display (Makes screen/EVF display look smoother when shooting in HS Continuous mode in SERVO). Only available when using RF lenses.

Is this correct?

Is what correct? The fact the distance scale shows up on screen in Manual focus mode with the RF lens, or that High Speed display is only selectable with the RF lens? As far as I know, both statements are accurate, but I could be wrong.

Sorry Basil, Number 2. I've not noticed this with my EF lenses. Maybe something to do with the speed of opening the aperture?
