Yep. That's about it. In short, yeah, I'm glad I parted with the money to get the camera.
What I like for the type of shooting I typically do (mostly landscapes):
- Silent electronic shutter. No, my D750's shutter wasn't loud enough that I think local wildlife were frightened and local humans were alerted that an expensive bit of kit was near, but it is nice to have a completely silent shutter - especially one at 20+ frames/second.
- 45,441,024 pixels in each frame. Yes, they advertise the sensor at 45.7 megapixels, but the image size is 8256x5504. This is fantastic for cropping.
- ISO 64. Yes, this has been available in the 8xx series for a while now, but this is my first foray into that realm - and I think it will be hard to go back to the world of base ISOs higher than 64.
- Focus stacking. 'Nuff said.
- Big buffer. Using a Sony 'G' series XQD card, I can consistently get a series of 22 images before the buffer is full (using full size compressed 14-bit NEFs). "Buffer full" in this context is a relative term as this card writes at 400MB/sec, so the pauses for buffer space are less than 1sec.
- The screen on the back is sharp. OK, so D500 users have the same screen, but coming from a D750, this was a very pleasant surprise.
- Touchscreen! Oh, this will require breaking some habits (like pressing the "+" button to zoom and then the cursor pad to scroll around), but this is huge for how I typically shoot landscapes (tripod using LiveView). Touch the screen and it focuses (just like a typical smartphone).
Still, all is not perfect in the World of Nikon...
- File size. I'm seeing average file sizes of 60MB (14-bit lossless compressed NEFs). Yeah, storage is cheap - unless you're talking about XQD cards fast enough to keep up with this beast.
- Memory cards. No, this is not the camera, per se, but this is a cost consideration as a result of moving to the D850 - and set me back over $400USD for new high-speed cards. Sony G Series 256GM XQD cards will set you back $380USD while 128GB cards are $170. Worst case calculations of 100MB uncompressed NEFs mean a 128GB card will hold just about 1200 images. While many people may consider that far more than enough for their needs, this was less than half the count from my last week-long trip through Colorado (not to mention last year's trip through Utah). If you travel away from your primary storage option for extended periods, expect to purchase additional cards or additional portable storage. (In my case, I opted for both faster cards and extra portable storage.)
Even so, I do not regret my purchase of the D850 in any way. Let me show you why...
Exhibit A - Local botanical garden with a foggy pond (shot about 30mins before sunrise); EXIF = 70-200mm f/2.8G ED VR II / 150mm / ƒ/2.8 / 1/50s / ISO 10,000
SOOC, without NR:
With NR (Luminance: 25, Detail: 75, Contrast: 30):
These are just about 1:1 captures of the master image. As you can see, this noise was easily cleaned up to an acceptable level - and I may be able to get a bit sharper detail with some more advanced tweaking. Regardless, Lightroom was able to render a very usable image with just a couple slider changes.
Exhibit B - Same park after the fog/mist burned off. EXIF = 70-200mm f/2.8G ED VR II / 200mm / ƒ/2.8 / 1/400s / ISO 64.
This image is just about 1:1 (SOOC!).
Here is a version at 3:1 (screen capture from Lightroom)...
This image was captured handheld from about 40 yards (36.5m) away. Note the strand of spider web to the left of the blossom. My D750 would not have picked up that detail from that distance..
Finally, Exhibit C - 70-200mm f/2.8G ED VR II / 200mm / ƒ/4.0 / 1/500s / ISO 400
This is just about a 1:1 crop, shot at minimum focus distance [15in/0.38m] - and SOOC!
If anybody's looking for a used, well-cared-for D750, let me know.
