A "Must Have" product if you have EF/EFS lenses!

This is an excellent product if you have a Canon R series mirrorless camera and would like to continue to use your EF as well as EF-S lenses. Here's an interesting point....If you're using this adapter on a Canon FULL frame R series camera with the adapter and are attaching a Canon EF-S lens, the full frame camera senses this and switches into "cropped mode". What this does is temporarily change the full frame camera into an APS-C camera while an EF-S lens is attached to the adapter. Here's an example...If you're using a full frame Canon R5 (45 mp sensor) and want to use an EF-S lens, the result will be a lower resolution image. In "crop mode" the R5 would produce a 17.5 mp image because the crop factor (1.6) is applied to BOTH the vertical as well as the horizontal. The result is 45/(1.6 x 1.6) = 17.5 mp. 17.5 mp is still a sizeable image but you should be aware of the downsizing of the image. This ONLY applies when using a Canon FULL frame R series camera with the adapter and an EF-S lens. There is NO image megapixel loss when using standard EF lenses with the Canon R series cameras and the adapter.

My EF lenses are better than ever!

This works great with my EF lenses, and except for the added length they feel like native RF glass. The only lens I felt compelled to replace was the V1 of the 70-200 IS 2.8 L - because the RF version is lighter and shorter and sharper (and the adapter makes the EF even more front heavy). Since I am currently using a 5d IV for a backup this will allow me to use the rest of my lenses until I jump into mirrorless with both feet.

Worth Waiting For

Well made product, as expected from Canon for one of their premier cameras. I'm happy I didn't give up and purchase a 3rd party adapter. This one fits perfectly and tightly, just as it needs to do to hold some of the heavier lenses. Thank you Canon!
