I would get one camera with a long, built-in zoom. Hopefully, it will fit into your pocket and do in-camera panoramas. I spent a week at Yellowstone with a Nikon AW100 waterproof camera, and I got 351 keepers.

"...Currently using a D750, and it does all that I want or need it to do..." Elmo55 you've already answered you query... It's not so much the gear or kit but the expertise and finesse of the one behind the lens...

You did not mention your intended target audience... so folks who have chimed in are simply whistling into the wind... They are likely unsure of their own kit decisions and lack the competence to analyze needs against their kit's ability to deliver... these folks lust after a "herd" acceptance mentality... The more users that validate their inferences the better they feel about their decisions...

Bottom Line? Photographic excellence is decidedly not a consumer commodity but rather a finely honed skill/craft that comes from an intimate familiarity with their tools and a solid grasp of "painting with light".

If you are questioning your kit rather than your ability to deploy it you've already lost the confidence and all hope of mastering the capture of compelling imagery.

My suggestion? purchase a second D750... That is if you are shooting commercially, otherwise practice your skills daily until you leave on your trip. Speaking of which how many images have your taken today? this week? or this month? Best to get off UHH and get behind your viewfinder... Test and Auto Fine Tune your glass... and by all means purchase a lightweight carbon-fiber travel tripod... A tripod is FAR more import to the image equation and IQ... Experience is a brutal teacher Elmo55.

Cheers!

I can appreciate your situation. Being a Canon shooter I have always been jealous of my friend’s D850. It seems to be that tank camera that will have a lot of legs. One other consideration already raised was taking this opportunity to go mirrorless. I converted completely earlier this year and have never looked back. I like the smaller size (not really weight as I still use bigger lenses), the quality and the speed of focus. It seems as though you have made the decision to get another camera, now just looking for the best fit. If the camera you want is available and you are able to afford the addition, consider what you might want for the “next” trip. Not just this one coming up. Just my 2 cents.

I've got to agree with Jerry. I know I'll get slammed for this. I went to Italy twice. In 2002 I brought my Nikon D60 (which was much smaller and lighter than today's models), flash, bag and some lenses. In 2017 I returned with my Nikon A900, which has a focal length of 24-840mm and is a joy to carry. 20 mp and a 3" tilting screen. I can tell you that I enjoyed the second trip much more and the photos were just as good. I know I'll get lambasted, but so be it. Great camera in my estimation.

Why not adapted lenses?

Elmo, I'd wholeheartedly suggest the D850 path. You might take the 750 along, as well.

I'm not sure I'd want to play mix and match using FX and DX cameras.

150-600 should do the job on a full frame?????

Being the Ebenezer Scrooge that I am, I'd say that the D750
is beyond as capable as you need, so that body is it.

You can buy sensational FX glass for far less cost than a D850
and the right glass does not depreciate (some even gain value)
anywhere as much as bodies do.

I'd say treat yourself, and get a Nikkor 24-70 f2.8 VR (and treasure this masterpiece)
to partner your 150-600.
If you are uncomfortable with changing lenses in the bush
plan your targets, and fit the appropriate lens before you head out into the wild.

I just recently got the Nikkor 24-70 f/2.8 VR; nice lens.

D5600 or Z50 w FTZ might be better choices.

Forest canopy not an issue in many western parks…including most E of CA.

Road tripping western parks very different than European cities. For the western parks weight and size not issues most of the time because you are in private vehicle. A light camera is good for trail hikes. The Z50 with kit lens 16-60 ideal for that.

I work with both formats... full frame and APS-C... generally using them for different things.

Primarily I use APS-C for telephoto work, while using FF for wide angle shooting.

This works out much better than cropping from a higher resolution camera. Even with 46MP full frame, once a D850 is set to DX mode (or, much better, the equivalent crop is done in post-processing) all you are left with is 15MP. You will get much more detail from the larger 24MP DX image the D7200 will make. In other words, the DX image from the D850 is 40% smaller than the DX image from the D7200. When you need the powerful telephoto shots, you will definitely see better results from the D7200.

So if it were me I'd pick up the D7200 to pair up with your D750.

You mention panos.... and that's a good way to "amplify" the resolution of your full frame camera if you have a scene that would benefit from gobs of fine detail. It's pretty much limited to stationary shots like scenery, but 2 or more shots can be combined to make a much larger image. Rather than using a wide angle lens for a single 24MP shot, use a normal to short telephoto and shoot a grid of images, which will end up much larger than 24MP. The sky is the limit, depending only on how many shots you're willing to take and later combine into a single image.... and perhaps the limitations of your computer system. (Mine bogged down quite a bit when I stitched together 35 images! But I just went and got a cup of coffee and eventually the image was completed.)

While there may be times you wish you had the D850 for a full frame shot with that 46MP of goodness, so long as the subject is cooperative, you can get there with your 24MP D750 too.

For example, I recall George Lepp shot an "gigapixel" eimage using a 70-200mm and taking upwards of 200 shots of a scene, which were then combined to make a huge image file with incredible detail. This isn't just limited to panoramas or even just to landscape oriented shots. Lepp shot some vertical scenes and even some macro and close-ups using this method.

There's specialized software and automated hardware available to assist with taking and compositing the images... but it also can be done manually and compiled with a lot of more mainstream image editing programs.

If wanted, more info can be found at gigapan.com, who offer both the software and hardware devices for the purpose, but also have a lot of great examples of of gigipixel images on their site.

I think you should consider cropping the 750 and using good pixel enlargement software if needed for larger printing.

OTOH, 2 bodies on such a trip would be wise. 8-)
