Praying that you have enough years left to fully enjoy a D750 and 200-500mm f5.6.

Only thing I know is The D750 has a larger dynamic range than the 6Dmkii but I got the 6Dmkii and did not regret it. I was shooting a 5dmkii beforehand. Got mine for 1299 from b&h on sale with no lens

Over the years, I have used Canon, and Nikon. I prefer Nikon's control layouts. Canon also changed it's mount, years ago, leaving many loyal Canon users unable to use their large lens collections on newer camera bodies. That upset many Canon owners, who then switched to Nikon. Nikon has changed it's mounts / lenses less radically, and many newer Nikon cameras can still use older Nikon mount lenses. Even though Nikon is now selling it's newer Z mount bodies, and lenses, it is still offering many F mount items, so Nikon users can continue using older lenses on the newer D850, D7500, etc, cameras. As such, Nikon is more respectful of it's loyal fan base. Given a choice, these days, I will always choose Nikon over Canon. I have a Nikon D7200 Crop Frame camera which has served me well. When I wanted to move up to Full Frame, I chose a Nikon D750. The controls are very similar to those on the D7200, so it is easy enough to use. The D750 is very good in low light. It is also better at video than the D7200 is. Not only would I take a D750, over any Canon, I DID so. You should not be disappointed by a Nikon D750, if you get one. Let us know what you decide.

Well, we have had a very nice 6-page conversation w/o a word from the OP. I hope he is OK.

Back in my film days, I did not stick with Canon, because Canon did not stick with me. I had Canon cameras, and lenses, and about the time I was getting ready for a new camera, Canon changed it's lens mount. So, I could not use my old Canon lenses on a new Canon camera. Since I would have to change all my lenses, no matter what I did, I decided to REALLY change all of my lenses. I switched to Nikon. I changed lenses, AND cameras, AND speedlights, etc. So far, Nikon has never let me down in the way that Canon did. I stick by those who stick by me. I kept enough of my old Canon gear to remind me of why I changed, and I got rid of the rest. I will never go back to Canon, for anything. Others still seem to like it, though. To each his / her own.

The larger issue than what FF model to buy, is if you need a full frame camera at all. Think about your reasons for upgrading besides a FF is the next shiny thing. If your current crop frame camera does everything you need there is absolutely no need to go to FF. I admit to being on the opposite end of the spectrum from the adrenaline-fueled upgraders and GAS sufferers here. I have a Sony a230, and an a350 DSLR that I got on ebay for $200 each. They are 8 and 10 yr old cameras. For what I need they are perfect. They make excellent quality images, the autofocusing is lightning fast, and the burst rate of 5fps is more than I'll ever need. I don't have to blow up prints larger than 11x14, and I don't have to shoot any dark scenes that require a higher ISO than I have.Advice to all. Think carefully before you buy something you really don't need.

Coincidentally I am also 72 !! I upgraded from the D200 to the D750 18 months ago, and more than happy with the better resolution I'm getting with the 24-70 F2.8 combination, not that I wasn't that unhappy with the D200. I havent used the 24-120, but I suggest, if you can, trying out the 24-70, and comparing. It is a bit of a lump though.

I have several friends who feel exactly the same way. I admit that I love using my 1980s Nikon lenses on my 2018 Nikon camera.

And, Alan, if people stopped buying things they want and only bought what they need, almost none of us would have cameras at all.

Yes you should do it if you want and can afford it. You just might take a lot more photos then you ever thought you would. Have fun.

If you have a money bucket for the camera you want... Get it. We only go this way once.

Good luck, Al

AMEN!!

Consider my favorirte Mr. Spock Star Trek quote:

"After a time you may find that having is not so pleasing a thing, after all, as wanting. It is not logical, but it is often true."

My experience is that new gear does not improve my photos unless I also can up my technique to take advantage of the improvements. My sensor is already better than the lenses I can afford, and my resolution is already higher than the biggest print i might want. And my photographic seeing is the same. So if you are better than your current camera I would go for it.

Exactly my experience... I had these really great FD lens bodies including the T90 - a good collection of FD lens and the next year of the big changeover "FOGETTABOUTIT."

Switched over the Nikon DX format camera and never looked back.

If you use "Quote Reply" your comments will make sense and have context. Otherwise it is unclear who you are replying to.

That is my general feeling as well. If one wishes to ask for help one should hang around to get it and answer clarifying questions or wait to post until that is possible.
