Read our detailed comparison of the Canon EOS R6 vs Canon EOS RP to find out their strengths and weaknesses, and decide which one to choose.
As an enthusiast that takes portraits, travel, some macro, some wildlife, and a desire to do more sports and birding; I've always wanted to upgrade my SL1 to a full frame sensor/mirrorless.
Price is a big deal for me, and I want to buy once cry once--i want a camera that will last me the next 8+ years. Reviews on the RP look great, and I don't pretend to be an expert--im confused though, because while the R6 mkii has a few nice features I can't see why it costs twice as much. Is the R6 mkii worth the upgrade, and/or will it be more future proof?
I have a R6 body with some lenses. First and foremost you should confirm the lens lineup is what you want. There really aren't any practical third party lenses for the RF mount, so what you see on Canon's site is what you should plan for. For me the lenses are fine, though I would be lying if I didn't mention my jealousy towards the X, E and L mount lense collections. The R6 body does two things well in my eyes: low grain high iso and superb IBIS. Personally, coming from an EOS-M system, these were the primary reasons I was wanting to upgrade in the first place. That being said, the R8 is now out and for the price I think I would go with that if I were buying today. As for other cameras, I find Canon cameras to be infinitely more comfortable than most others. Judging by pictures I've seen, perhaps Nikon or Lumix cameras might be fine these days, but the Sony and Fujifilm cameras I've tried were designed for either aliens or small hands. Neither of what apply to me.
Also regarding price differences, NOTHING in these price categories are going to be 1:1. This applies to literally any kind of non-essential good. After a certain point the value/dollar exponentially decreases.
