The shutter life rating on the 6D’s shutter is 100K actuations. The 5D3 is rated for 150K. If you are the kind of user who is likely to hit the higher shutter count during your use of the camera, this is definitely a consideration. That being said, replacing a shutter is around $300; it’s not the price of a new camera. Re: Canon 5d MKIII vs the Canon EOS R. Mikeys wrote: Nice camera. However check if shadow recovery is on a level you expect. R suffers from Banding. The R does feature some banding in certain extreme situations, however this would require an extremely underexposed image (human error) which you are trying to recover. Although, the Canon 6D lacks some features that some other full-frame DSLR cameras at this price range have, such as the dual card slots and the autofocus system.

In low light noise the 6D even has an edge over the 5D MK III, but it is really splitting hairs, but the 6D features are less than the 5D MK III and the 6D with only one SD memory card slot and requires using the menu system to change white balance, so not as easy with buttons to quickly access some features.
