I have a D850, a D750 and a D7100. All great camera, all give me great results.
So comparing the D850 to the D750.

Both can get good images to the same High ISO. Neither is better in low light.
File size -- the D850 files are HUGH. You better have a fast computer for post processing with the D850. My current PC can zip through post processing with the D750 files, but becomes very sluggish with the D850 files.

Lens Quality. I have the Nikon 24-120 f4 lens -- great images on both cameras.
I also have the Nikon 28-300 lens -- when Pixel Peaking (viewing at 1:1), very sharp on the D750, not as sharp on the D850. But if I view the D850 images at 2:1 (which is basically the same resolution as the D750, the D850 images have the same visible sharpness as the D750. And when printed, you can not see a difference in sharpness.

Cropping -- Much more options with the D850 -- there are more pixels, so when you crop you still have a lot of pixels left..

Bottom line -- Both the D750 and the D850 are awesome cameras. Both can make you very happy.
I still use both cameras depending on what I plan on doing with the images. For images that will go on the web (social media), I mostly use the D750 because the file sizes are smaller, and I can post process a lot faster. For images where I am trying to be an "artist", I mostly use the D850 since there is more pixel details to finesse.

Hint -- if you are into HDR or Luminosity masking. With the D850 files, plan on sitting and watch your computer chug through the post processing. Significantly slower than the processing time required for the D750 files. And the results are not that much better from the D850 over the D750.

Hope this helps.

I owned the D750 and own the D850. The D850 is a new camera for me and I am going to use it for both landscape and birds in flight. I own the d5 so I don't have to go to the expense of getting a d5 battery to put into the D850 to get 9 frames a second, and I have the charger for the D5 so I don't have to buy that either, just the battery door adapter which by Nikon standards is actually cheap.
I liked the D750 and believe it is a great camera for the price. If I were buying it again I would wait about 6 weeks to Black Friday when Nikon usually throws in a free vertical grip and discounts the camera.
It really is not fair comparing these two camera's as I believe they are both great for what they are intended. The D750 is the best Nikon OUT OF THE BOX that they ever produced. And it is great in low light.
For me, I love the touch screen on my D500 and I was happy to see that the D850 has the same feature. You would be very happy with either camera. If it were me I would go with the D750 and buy quality Nikon lenses. High end Nikon glass can go on any Nikon camera down the road. Glass is, in my opinion, more important than the body. So, get the D750 and use the savings to get high end quality Nikon glass.
By the way, here is just one of many comparisons you can find on line.

In my humble opinion, if money is no object buy the best at the local store and support your community. The D850 is likely the final and best Nikon Dslr. If you downsample it's images to the size of the D750, they will be both sharper and less noisy even in low light . + the bragging rights of owning the best. Alternatively the D750 is more than adequate, 24mpix is very ,very sharp. If you never print extremely large format or only view on screen , mostly shoot events,
or family photos there's almost no advantage to the 850. Actually you may like the faster post processing, the flip screen, the built in flash of the 750 more.
Maybe rent both for a few days, only you can tell what suits you better.

If you are thinking of a d750 why not the Z6?
I have the d750 and love the low light ability but think the fold out screen is essential for low and high level options.

I own a 750 and use it for sports, wildlife and photos of my family. I also own a 700 and I prefer the 750 because of the weight. If I had the money, I would likely try out a 850 because of what people are saying about the cropping. However, for the money, the 750 is hard to beat. Now, I've always been told that its all about the glass. So I can also understand why people would say that you need the best lenses for the 850. If money was a constraint, I'd go for the 750 and better lenses. If money was no object, then of course the 850 with the best lenses. However, if the choice because of budget restraints was, a 750 with good lenses or the 850 with avg lenses, I chose
the 750 with good lenses every time. Unless you're a pro, I would think the 750 will do just fine for almost all weekend warriors. I have several 20x24 and 16x20 prints on my wall, that I don't know how much better using a 850 would make them look, unless like some are saying, you cropped the hell out of them.

One last thing, some have mentioned to only use Nikkor lenses with a 850. I'm sure some Zeiss owners would disagree. I know I would with my Voigtlander 58mm. It produces better images on my 750 than probably any of my Nikkor lenses and I have some of the best they make. I will say the Nikon 20mm 1.8 is an excellent lens that compares in quality of images to the Voigtlander. I'm sure there are others, but there are 3rd party lenses I would use on a 850 and be very happy with the results.

I don't know how much that helped, but just my opinion.

I have had a D750 for a few years and it's more than anything I could want from a DSLR --the 850 is overkill for the vast majority of phtographers in my opinion!!

RickTaylor

I have had them both but the 850 is the winner you will not be sorry. A truly amazing piece of equipment if your finances allow you to purchase the 850 don’t give it a second thought

I have had my D750 for a number of years and am very happy. It is lighter to lug around and for most of what I do, I find 24 mega pixel to be more than adequate. If you plan on blowing up your images really large then going to D850 would be beneficial. Decide based on what you plan to do with your camera and its results. I shoot both raw and jpeg and total file size per shot is around 40MB even on D750. As you go to higher resolution you will need more storage capacity both in the camera and for archival (I do realize memory is cheap). I would rather spend that extra $ in better lenses. Hope this helpful.

I own the D750 and D850 and use the D750 less and less, not because I don’t like the D750 (great capability for the price), but because of what the resolution of the D850 allows me to do in post. My D850 + Sigma 24-105 f4 Art has become my travel companion!

I have both the D750 and D850. The D750 has sat since I got the D850. I just keep it for backup. Both are excellent camera bodies but the auto focus is great and dynamic range on the D850 is insane. I've taken pictures that required just a single shot with the D850, without clipping either highlights or shadows, that would have definitely required at least 2 shots with the D750. I find very little value in the touch screen on the D850. I almost never use it. But the quality of pictures that come out of the D850 is amazing. But by the time you buy batteries and memory cards for it the price is fairly steep. The D750 is still a fantastic body though.

Of course I think you do need to have really good lenses, like someone else mentioned. Originally I bought the Tamron 24-70 and 70-200 and 15-30 and after 2 weeks of fighting to get them to take a decent picture I gave up. I did 3 different methods of fine tuning, even using the Tamron dock, and never could get a great picture from them. I sent them back and bought the Nikon trinity (14-24, 24-70, 70-200) and they worked perfectly out of the box and the picture quality is fantastic.

I have both, and I like them both for studio work (though for me they are too bulky to lug around all day in the field). I like the fact that the D850 has no AA filter, so the potential for resolution is marginally better. I like that it has 46 vs. 24 mp. You will be happy with either camera.

My first full-frame camera was the 750 which I paired with both the 24-70 2.8 and the 70-200 2.8 lenses. In almost all cases it was excellent -- except for extreme low light and fast action (I shoot indoor rodeos). I rented a D5 to get the higher ISO capabilities but was frustrated with the lower megapixels (which meant less ability to crop). When the 850 came out, I hesitated until I kept reading over and over again how the megapixels would allow for much more cropping ability -- and since I also photograph wildlife, I needed that capacity as well. I've been shooting with the 850 exclusively since March and have been thrilled with the image quality, ISO capability and the greater ability to crop. Since you're planning on the high grade lenses, definitely go for the 850. You won't regret the purchase.

As for the XQD cards, I love how fast they can process images, and for the second card slot, I've been purchasing the Sony SDXC II cards (read speed 300mb/sec, write speed 299mb/sec), which has allowed me to continue to shoot the higher sized images without a loss in processing speed. FYI -- the 750 can't handle the SDXC II cards so the max speed on SD cards in that camera is 95mb/sec.

The D750 has too many shutter issues for me to trust buying one. The D850 has a titanium shutter mechanism and titanium case. Plus it's the best sensor and fast focus system Nikon has to date. I feel better overall than the D5 which is twice the price of the D850. Get the battery grip also. It increases the FPS from 6 to 9. A 30% increase along with a fully functional vertical grip also. This will be the last camera you will buy for the next 10 years or more. I own a D500 the D850's baby brother. I want a D850 So bad but can't afford it. If you don't really need a full frame then buy the D500 instead. It has the newest sensor, fastest focus system, and real 4K video. Plus you can use your existing DX lanes. Save money and buy some nice f 2.8 fast focus glass instead of too much camera.

The QXD is really expensive. I know but the XQD is faster and more reliable. It's good to have a back up card too. Try it you'll like it. Buffering is cool.

throughrhettseyes Loc: Rowlett, TX

Yes and I love my 16-80mm f2.8 DX too. You can use your DX lenses on a FX camera in the crop mode.
