I moved from Canon to Sony full frame mirrorless in 2013 and have since had their A7R, A7S, A7 II, A7R II and A7 III. The A7S is still one of the, if not the best, low light camera on the market, although I've found the A7 III to be a very good low performer as well and it is reasonably priced. If you want a higher resolution camera, take a look at the A7R III or IV.

Initially I used MetaBones and Sigma's MC-11 adapters with Canon lenses (and still do with a couple of Canon lenses I love). Since 2013 I've slowly acquired a few Sony and 3rd party FE mount lenses; however, I also love the old Minolta AF lenses with Sony's LA-EA4 adapter.

Good luck in your decision making.

You've probably been listening too closely to the wrong people ... Your D500 could easily be the last camera you need this lifetime, certainly it's barely used at 10,000 clicks. But, we all know the grass is always greener when captured with a mirrorless camera.

Consider your current Nikon lenses and whether you want to dump them all or retain DX lenses on a cropped Z50 or FX lenses on the various Nikon FF mirrorless options. After a lifeline of Nikon, the reasons to change to another brand are not compelling, unless again, you've been listening too closely to the wrong people.

Hi;
I have been mulling around the idea of going to a mirrorless DSLR. I understand the consequences. It means buying all new lenses, etc. Currently, I have a Nikon D500 with only about 10,000 snaps on the shutter, and about a half dozen various lenses. Over time I went from a Nikon D200 to a D300 to a D7000 (I used that as a back up to the D300) and finally went to the D500. I can't say that I'm unhappy with the D500. It takes excellent photos and I have had no issues with it.
My thought is this: Going forward, in not too many years down the road, ALL new cameras will be mirrorless. When that day comes, existing cameras will be worth something less than what they are worth today.
Since going mirrorless will entail getting all new lenses, it frees me to look at other camera manufacturers.
The three top contenders IMHO are: Nikon, Canon and Sony. I do a fair amount of indoor photography where I can't use a flash, so I need a camera with a decent ISO rating.
I guess the only other deciding factor is what type of trade in I can get on my current equipment. I'm looking for suggestions, with pro and cons various models. Any help would be greatly appreciated.
