RF 70-200 or EF 70-200 with Converter for EOS R

Hi there,

I am making a decision to buy one of these lenses for the EOS R, RF 70-200 or EF 70-200, and I need some suggestions badly.

I am thinking of getting the EF mount for two reasons, the price and the possibility of adding a 2x teleconverter so that I can have a 140-400, as I read some posts suggesting it's quite impossible for Canon to make an extender for the mirrorless series regarding the short distance between the lens and the sensor.

Though, I do concern about the AF speed and the image sharpness when stacking the EF-EOS R converter and the extender, as well as the weather sealing.

Canon did say that the extender is compatible with the converter but I do not have a chance to test this specific combo in person so I'm hoping I may get some help here.

Thanks, everyone!

It depends on how long you you want your transition from all-EF to all-RF to be.  If you expect to be using EF lenses for the next few years, you lose nothing from buying an EF lens now.

I'm currently all R with camera bodies, but I still don't expect to buy an RF lens for maybe another year.  The only one I find compelling right now is that small-and-light 70-200. I might be compelled to buy that one, if there are end-of-year deals, and the 24-105 by the end of the year (because it's already so affordable) by the end of the year.

Whoever told you that a teleconverter can't be made for mirrorless cameras was blowing smoke up your skirt, btw. There are teleconverters even for Leicas.

That doesn't mean, however, that Canon is going to produce one any time soon. That may be a good reason for you to go with that EF zoom.

Don't be afraid to buy now the lens you need now.
