I'm not a professional, but a fairly seasoned and avid amateur. For Canon DSLR's I started with a T4i, then to a T6i, then a 5d Mark ii and a 6D Mark ii. The R10 is superior to all these cameras in every way. It's fast, light weight, accurate colors, incredible auto focus, and loaded with many of the features the big brother's R5 and R6 have. With a good lens, it's very capable in low light also. The Digic X processor is a huge leap in technology from its predecessors. Even the professional high end cameras with a Digic 7 can't compare to the lowly R10 with a Digic X IF you put a good lens on it. The RF lenses and head and shoulders above the EF lenses and more option are becoming available all the time. A lot people complain about the lack of 3rd party lenses. Frankly, I've never owned a 3rd party lens and don't ever plan to.
