Stay alert, control the camera, save photos

There are not detailed reports on those TCs to make those judgements. The Sony TCs are exceptionally good and better than Canon's EF ones according to those who have used both. The EF 1.4xTCIII is very good but the 2.0xTCIII takes quite a hit on IQ. I hope Canon has new formulas for the RF extenders - they are expensive enough. Nikon's 2xTC is garbage, but they have also brought out new ones today for the Z series.I think it is safe to say that is based on current cameras. The Canon TC's are rated for what looks to be the best AF out there on the R5 and R6.
