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!

I don't own the rf70-200L but I do own an R and the ef70-200L is ii, and it's considered perhaps the best ef lens Canon makes...  it's awesome.  The iii version changed only the coatings.  the rf version has had great reviews, and even if the image quality is slightly improved, the only real advantage I see is the compactness.  If it were the focal range I'd want for travel, I'd buy one, but it's not.  I'd like a 100-400 compact for travel to complement the excellent rf24-105L.  I currently travel with the ef70--300L is 4-5.6, but don't need the 70-105 ovelap, and want a compact faster telephoto with the extra reach.
