T6s vs 77D autofocus

I think you would really like the Canon T7i (800D) or the Canon T8i (850D) cameras. For people with shoulder or wrist pain, the M mirrorless cameras are really neat in that they are so lightweight with the EF-M lenses. But another problem with that system, is that Canon has not developed their own EF-M lens for that, that exceeds 200mm. I don't know if there is a design reason for that, or if that is just something that has not done yet. If you learn or discover workarounds for the M mirrorless cameras as I have done, that might be an option for you too. But if you are used to the Canon DSLR systems then you might prefer that.

If we purchase M mirrorless cameras, buy an adapter, we can use the EF-S lenses, but then the advantage of being lightweight is not as great. But boy...those EF-M lenses with the M mirrorless cameras make it so nice in terms of weight. You would have to hold one in your hands to see. When I first received them through the mail (the cameras and the EF-M lenses), I thought...wow, these are really tiny. But I don't think I would have believed it with just seeing pictures of them.

You might like to see this photo I took of them. On the left side is the Canon T7i (800D) camera with the Canon 18-135mm USM lens. The other cameras are the Canon M50 MKII with the Canon EF-M 55-200mm lens or Canon EF-M 15-45mm lens (from left to right). I know I probably have too many of them but they are fun toys. I got that Canon 18-135mm USM lens for a crazy low price of $150 (USD) or thereabouts on Ebay. I've never seen one that low in price after that; I just got lucky.

I probably should buy a Canon 90D too, but I think I have so much already.
