So when I bought back into Canon with and EOS R I did not run out and buy all the big and expensive RF zooms I owned when I first shot Canon. I had moved over to Sony where I do have all those lenses but since I wasn't sure about the EOS R I hesitated.

I know have the R5 on order but don't have it in hand yet since I waited till October to decide to get it. I was not in a rush since I had plenty of gear to work with and wanted to see and read the reviews on the R5.

So now that I am buying back in I trying to decide between the two RF 70-200. In EF mount I owned the f/4L version first but did upgrade to the f/2.8L when I had the chance so I know the pluses and minuses of smaller f/4L vs the faster f/2.8L. The reason I am hesitating is when shooting with the EOS R I took the opportunity to buy a lightly use EF 70-300mm f/4-5.6L IS. When you compare its adapted size and weight the extra weight gets you 100mm more reach which for travel is really attractive. The weight difference to the new 70-200 f/2.8L is the adapter only. It is also the height of the adapter taller. Here is a size comparison curtesy of camerasize.com

Adapted EF 70-300mm f/4-5.6L IS vs. RF 70-200/4L IS and RF 70-200/2.8L IS

Edit: Also have the control ring based adapter so I get that functionality already with the EF lens.

So I am wondering if its worth spending 2x or 3.5x more money for either of the RF lenses. In the past I would rush out and spend the money for the latest and greatest but I guess I am getting more conservative in my old age especially since I am not getting to travel as much right now to take advantage of my kit. Also I know the RF 70-200 f/4L won't take the 1.4X teleconverter which I might have considered if I went down that path

So what do you think? Any opinions


Honestly, I think it depends on if you need the range or not.  The 70-300L is a good lens, and sharpness/colors etc are not going to be a dramatic difference between any of these lenses.  If you need the range, the 70-300 is the only one that can get you it, because neither of the 70-200 lenses take teleconverters.

If you don't need the range, then it gets more challenging.  Do you want F2.8 and native lens?  Do you want f4 constant aperture and the smallest lens?  Or do you want the largest range and cheapest, but also the largest and non-native?  Tough choice.
