One listing claims the D7200 weighs slightly more than the D750. Others have the D750 slightly heavier (840 vs. 765 g). Probably not noticeable.

I was happy for many years with Olympus cameras. I went from the OM10 to the OM2s and have several Olympus and other brand lenses. When I bought a Nikon D60 i found the weight and size difficult. I finally discovered the Olympus micro 4/3 mirrorless line. The bodies are comparable to the old Olympus film cameras. I have the OMD5ii. This is in the middle of the fleet. The OMD1 is professional-grade and the OMD10 is consumer. Olympus just sold its imaging component to another company so I don't know what this means for the future of the cameras, but for now I am very happy with the OMD5ii. It's complex but easy to use after you read a little bit in one of the non-Olympus guidebooks.

Why change any of your lenses? Look at the Nikon D5x00 cameras. They should use all your lenses and be a major upgrade from your D40. Good luck.

...my particular learning curve re. mirrorless was not very abrupt. Very easy, actually. The Nikon menus carry over quite nicely and there were just a few little ideosyncracies to get by...it was a pleasure to add a Z6 to my "stable" of bodies. YMMV, of course, but I don't think an experienced photographer, working in-brand, will have many problems operating the equipment. JMHO, but, then, I've actually done the deed, so that says *something* I suppose.

I would suggest looking at a Nikon D610 or 750. THey are relatively cheap -- look at e-infinity in Hong Kong but sometimes on sale at B&H. Full frame, light and really nice to use but don't pay more than around $800 new.

It’s still a far cry from using the information screen and having external controls. With external controls I can change virtually any shooting setting without taking my eye away from the viewfinder.

What is it with people that when someone mentions an interest in newer technology they want to steer them to technology 6-7 years old?

Leo_B Loc: Houston suburb

Maybe that it fits within their budget, it is 3-4 generations newer tech than what they are leaving and fits the perceived shooting interests and competency level they've expressed? And did I mention it fits their budget?

davidf_logan Loc: Logan, Utah

Because it was just a suggestion -- which is what the OP was asking for. It is a way to get a very good full frame camera for not a lot of money. I supsect that the OP asked because he or she did not necessarily want to buy the very latest model. After all, if you want the latest technology just go to Nikon's website (or Canon's etc) and see what is the latest. Not hard to do.

As for your snarky reply, why is that people see the need to interject themselves into a conversation when they have no useful input? You don't even make any useful comments on what is wrong with this "old technology."

Thank you, Leo!

My experience with photography is similar to yours... began in college with Nikon SLRs and continued sporadically during my working career but primarily while on vacation. Then in the mid-2010's I discovered Nikon's Df, and one look at this camera took me back to the classic SLR's I had used in my youth, and I bought one. The new Nikon Df literally re-ignited my passion and enthusiasm for photography. I encourage you to take a look at the Df and see if it grabs you. The good news with the Df is that it accepts pretty much all older, vintage Nikkor lenses, including pre-AIS, in the event you still have some of the old Nikkor lenses from your pre-DSLR days... https://www.nikonusa.com/en/nikon-products/product/dslr-cameras/nikon-df.html

How much size, weight, and cost are you will to deal with? Medium format will be on the high end of that and 4/3rds will be on the low end. Full frame is below medium format and above APS-C. And APS-C is above 4/3rds. Some other factors that can affect your decision are number of pixels, DOF, and ISO.

Do you have some lenses that you used on your D40? If so, your best bet would probably be a D7200. Those are discontinued and only available as refurbished, but they are one of the best, affordable DSLRs that Nikon has made, to date. The replacement model, D7500 is faster, but lower resolution, less dynamic range and has a few other takeaways. The D500 is further upgrade, but more expensive (~$1500). Cheaper D3000-series and D5000-series Nikon models aren't able to work with a lot of the older lenses. D7200 can (as can D7500 and D500).

An alternative, if you wanted to try mirrorless, would be the Z50. There are advantages to mirrorless cameras, but disadvantages, too. The same can be said for DSLRs. One of the disadvantages is that the Z50 uses a different mount, so you would need to use an adapter to fit any F-mouny lenses you might have from your D40 onto the newer camera. You probably should plan to eventually add some Z-mount lenses for the Z50... but as of right now, there are only two of those that's specifically designed for APS-C format (16-50mm and 50-250mm). You can use the full frame design Z-mount lenses on it, too... but they may be bigger, heavier and more expensive. If you consider these, you should carefully compare mirrorless versus DSLR and the D7200 versus the Z50.

D7200 are selling for $694, refurbished by Nikon USA. Used ones can be found for $500 or less.

Z50 can be bought new for $857.
- If you buy it bundled with the FTZ adapter, that adds another $50. (Saves $200 buying the adapter separately.)
- Z50 bundled with Nikkor 16-50mm lens costs $997 (+$50 for FTZ adapter)
- Z50 bundled with Nikkor 16-50mm and 50-250mm lenses costs $1347 (+$50 for FTZ adapter).

All the above prices are from B&H Photo. You might want to shop around, but watch out for stores not authorized by Nikon, gray market and bait n switch. I'd be cautious of any place offering any of the above for much less than B&H.

If your are not heavily invested (bodies, lenses etc.) in Nikon, and according to your statement, you liked the old Olympus, I'd seriously look into the modern Olympus OM-D digital mirrorless series. Light weight, compact with a slew of lenses to choose from, and packed with some of the most innovative features in the photo world.., lots of cam companies playing catch up. I'm just sayin'?
