Canon's full frame implementation of the latest technologies delivered the RF Mount. The RF lens mount retains the large 54mm inner diameter advantage of the EF mount (for reference, the Nikon Z mount has a similar 55mm diameter, the Nikon F-mount is only 44mm, and the Sony E mount is 46.1mm). While retaining the rigidity/durability/strength The 1.4 is clearly sharper from f2 and beyond. There is no 1.8 from the 1.4 to make a direct comparison, but in all the ones you can the 1.4 is sharper. The CA is slightly lower in the RF 1.8. Also, the 5Dsr which is testing the ef 1.4 is 50mp. The R5 is 45, so the 1.4 looks sharper even on a higher mp sensor. The EF-M 18-150 is significantly sharper then the EF-S 18-135, any of em. The MTF graphs confirm this, as do many accounts from folks on here. The 11-22 is much sharper then the EF-S 10-18. The EF-M 22mm F/2 STM is a full stop faster then the EF-S 24mm f/2.8 STM, and 2mm wider. Key Features. Canon EF/EF-S Lens to MFT Camera. Maintains AF, AE, and IS Functions.
