First of all, I’d like to say that Nikon has totally gotten the Wi-Fi right! The Nikon D750 works like crazy.
After shooting for the day at the Mermaid Parade in Coney Island, I was transferring the photos to my phone while on the subway and posting to social media, immediately.
Right until the subway went underground.

Just had to open with that as I’m very excited about that feature. (yes, used a bit of Instagram filtration)

Ok, let’s get down to rest of the real world review.
The Nikon D750 has become the choice for photographers everywhere with good reason.

Smaller form factor than the D810, outstanding auto-focus choices, (I go for the c with a single) and a ton more.

The auto-focus was super fast and dead on. The choices of the grouping of focus points was a fun exercise till I found the right one. Went with a group of 4.
The range of the focus points, while still at 51,like the D810, had a smaller overall coverage on the whole versus the D810.

The new deeper grip,smaller size, and weight made the D750 a very comfortable camera for a day’s walkabout. Felt the difference from the D810 immediately. I have been going with a wrist grip from Cotton Carrier for the street shooting. Always in the hand, and always ready. The lighter weight and smaller footprint help that comfort factor.

Another added feature is the U1 and U2 choices for setting your customized settings depending on the situation. Easy to get to and very handy in a rush.

Some photogs have even been posting their settings for landscapes and portraits for you to emulate, but it’ll tag the images with their metadata if you go that way.

Find you own way on this front. Experiment and customize to your specific needs.

Another asked for and answered feature is the variable angle LCD.

get all artsy and shoot the ground.

Finally! The real deal vari-angle LCD on a full frame Nikon camera. Great addition for the street photography side as well. My favorite use is shooting above a crowd, in what call the Hail Mary shot.

The megapixel wars rages on, but this unit sits at a very comfortable 24mp. That is your first difference with the D810. 36mp vs. 24mp. What you need, depends on what you shoot. Are you in the studio? Landscapes? Still lifes? More MP is always good, but you’ll pay and extra $1000. for that. Maybe use that money towards good glass.

Here is a shot right out of the camera. No post.

And a blowup from that frame:

The 24MP could be all you are looking for.

The advantage of the Nikon system is also the legacy of the developed tech.
You will get an outstanding video camera in the d750, and many of the same features in the D810 are present.

Like the D810, the D750 can output uncompressed video to an external recorder and simultaneously record compressed video to one of the SD cards. The camera has built in stereo microphones but also features a 3.5mm jack for an external microphone or headphone. I’m a fan of the flat pass ( kinda like video RAW)
Remember, you’ll have to get you post production chops honed if you want to use the flat pass, which need to be color corrected to the best advantage. A skill you can learn that will give you a better image, in my eyes. Or go with the color from the camera, which is still awesome.

And another word about the Wi-Fi: no more Nikon dongles!

The app worked flawlessly, and the connection from the camera to my iPhone was fast. I was able to review over 1000 images pretty quick and post appropriately. Admittedly, it was Instagram and Facebook, but that what we do.
And not a clunky proprietary site that made a transfer hard. They smoothed out the rough edges. As you can see, it loaded the JPGs and NEFs. I always shoot both, so I can post a smaller file fast. Last year, The Guardian in the UK contacted me 10 minutes after I posted an Instagram shot asking to use it, with credit. Heck yeah!
