Hi!The r6 replaces the 6d (full frame mid-range in older generation SLRs)The r5 replaces the 5d mk4.The r was the first canon hybrid.It used the sensor of the 5d mk4.The rp is the r " first price ".

Now, for the uses: The r6 is for me a mix in the spirit of the old 7d (which I had ten years ago, the mk1) for the sporty side and speed in general . The r6 buries the r for anything that requires a bit of speed. But it has a lower resolution. The r6 is to be used for photos of children, animals, sports.

The r with its sensor (even if this one is less outdated) will be very good for portrait, landscape. Attention, outdated, I'm not saying it's worthless (it still has the sensor from the old 5d, once again, so top of the basket), it's just that the af, the viewfinder , etc., are below r5. It's a question of choice. Honestly, I scrapped mine cheaply a year ago, and I regret not having kept it to fix a second lens on it.

The r5 will bring you possibilities of settings superior to the r5, the possibility of being able to crop (resize) your photo: if you only need half of your 45 mp photo, you will have the half, more than the r6. You can crop with the r6, but at the risk of showing aliasing. The r5 also adds large (higher) capacities to the r6.

The r3 shoots photos the size of the r6, (24 mp), but at 30 fps, and eye sight, which is apparently revolutionary, and finally a seized full frame.

Afterwards, who can do more can do less, but not the other way around.
