This is the fifth Nikon DSLR that I've had, (D40X, D200, D300, D300s, and now the D750). I've been waiting for years for Nikon to produce an upgrade to my now 5 year old beloved D300s. As a professional photographer, it was really important that my next camera met my strict set of needs and wants. Sure, Nikon produced the D7000 series, but that took a professional camera and dumbed it down. While the D800/810 are almost unanimously the best out there, I can't shoot a wedding with 36MP photos. I don't even want to think about how many memory cards I'd need to shoot the 1-2000 RAW photos taken at an average wedding. The D4S is lovely, but I can't quite justify paying that much for a camera. The D600 was a bit plagued, and after shooting with a rental D610 I was left with lots of frustration and questionable images. The D610 had some weird white balancing and exposure issues. Also, for my large hands the grip felt incredibly cramped, which is a big deal breaker when this camera is going to be attached to my arm for 12 hours a day. Could Nikon not produce a proper successor to the D300s/D700 in 5 years?
Luckily, the D750 really seems to be that camera.
-The grip, while as narrow as the D610, is much deeper, which makes all of the difference in the work.
-Focus is incredibly fast and accurate, even in really low light settings.
-Photos are crisp and full of detail (even with the AA filter).
-The rotating screen, while built very solidly built does scare me a little, so I'll use that sparingly. It's bright, and the addition of white (as well as RGB LEDs) really bumps up the readability. The screen isn't quite as nice as a retina display, but it's not far off.
-The top screen (while much smaller than the D300s) is bolder and easier to read.
-Speaking of easier to read...the viewfinder display is unreal! It's white and bright and an upgrade that I love but I didn't even think about.
-Controls and menus are a bit frustrating. Had an issue with autofocus trying to focus before every picture in a burst and it took quite about 30 minutes on the phone with Nikon to figure out what was causing the issue. It was a stupidly simple fix. Once I figure out this camera and get used to the slightly different button order, it'll be fine.
-Speaking of burst, 6.5 fps may not be the fastest out there, but it is plenty fast for me. A little sad that the addition of the grip doesn't add an extra fps or two.
-Shutter sound on normal continuous high is actually quieter than the quiet mode on the D300s; a huge plus for me.
-Wireless capability. I'm not going to lie, this was a HUGE draw for me. I've used EyeFi cards, and they've been great, but their range was about 5 feet and the connection took quite a bit of time. The Nikon built in WiFi is fast and was able to trigger the camera from my phone from 25 feet away. Brilliant.
-And I saved the best to last. The low light performance of this camera is unlike anything I've ever seen. I think it may even be better than the D800. Completely usable photos up to 6400 ISO, and I wouldn't hesitate using a 51,200 ISO photo in a pinch. They were surprisingly low noise. Honestly, the 51,200 looked cleaner than a 6400 photo on the D300s
And now the negatives.
-First is the biggest one. The buffer. It's just ok. I could shoot burst mode for days with the D300s but the D750 only allows for a few seconds. I wish that it had the same buffer as the D810.
-Screen is a little bit slow to wake up when turned on with MENU or PLAY, etc.
-Camera is a bit too small for my hands, not unreasonably so, but I'll definitely be purchasing the grip soon.
-WiFi is unsecured?!? A big oversight for Nikon, which should (hopefully) be corrected with a firmware upgrade soon.
-No screen protector? This is the first Nikon that I got that didn't come with one. Even though it has the tabs to attach it, Nikon doesn't currently have a screen protector for the D750 (I spoke to Nikon customer service) I'm sure this problem will also be corrected soon, but these are the problems that you get when you get one of the first cameras off the line.
-Why does it have the spin dial controls at the top instead of the 3-4 button controls of the D800/810/D4s?
-The photos are too.... beautiful?
Honestly, try as I might, I couldn't come up with more than those slight complaints. Sorry this review was a bit long, but I am psyched about this camera, and thought it was deserving of a full review.
