Here we have a look at the autofocus performance of the new Canon EF-RF 0,71 Speedbooster on the Canon EOS C70 together with the Canon EF 24-70mm /f2.8. We compare the Dual Pixel AF-Performance of the C70 with the Canon RF 35mm (without the new Canon Focal Reducer) as well as with the new Canon Speedbooster and the EF 24-70mm /f2.8. We also compare the change in perspective with and without the 0,71x focal reduction @ 35mm between EF and RF.
