I cannot believe that canon brought out the 70-200 2.8 it was stupid because it will not take a 1.4 converter so it was a waste of time ? and I think it will be a flop in comparison to the old ef one
Yes, stupid Canon. It never ceases to amaze me how a few random people on the internet know way more about making and selling cameras and lenses than the global, multibillion dollar company that has dominated the ILC market for two decades.
Speaking for myself, I had the EF 70-200/2.8 IS II for 10 years, and both the 1.4x and 2x TCs (initially the MkII, replaced with the MkIII). I used them regularly with a 300/4 then with the 600/4 II, and occasionally with the TS-E 17/24 and MP-E 65. Over that decade, I used a TC with my 70-200/2.8 maybe 5-6 times. Results were acceptable, but not as good as with the 100-400 or 70-300L.
I sold my EF 70-200/2.8 II and bought the RF 70-200/2.8. I’m very happy with the much shorter collapsed length which makes it easier to pack, and the lighter weight is a great bonus. I’m not at all bothered by the lack of extender compatibility.
Do you supppse maybe Canon did a teensy weensy bit of market research before changing the design of the RF 70-200 lenses? Naaah, they’re stupid, right?
