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 bought the EF version, but here are my thoughts:

EF version:

-- hide signature --

I own a 1DXii and R, so the EF mount works on both;

-- when shooting sports, I don't like the telescoping RF lens

-- it was cheaper

RF version:

-- when stored in a bag, it takes up significantly less space than the EF;

-- you don't have to cuss when you forget your EF to RF lens adapter.

Truth be told, I don't use that focal length as much and usually end up shooting EF 135mm and 200mm primes, so that was another reason to save some money.

If I only had an R body, then I would definitely get the RF lens as forgetting or misplacing the adapter is a real issue that has caused me pains several times.
