That really is the issue. Printing shows the limits of a system. If you don't want to (or can't) carry a heavy system, and you are not printing large, then it doesn't matter.

I used to shoot medium and large format film, and most of the time printed 11x14. At that print size I could have used 35mm, but I liked the look.

So I guess that the camera doesn't matter as long as you get the look you want and the print size you want.

Love my D700. With the vertical grip and AA batteries you get 8fps. It's solid but check the rubber, they have a tendency to come lose.

I use a Spider Pro, and it works well. Short term solution is to make a couple prints then hold them up next to the monitor and adjust the color and brightness. The problem will then be the room lighting, brightness, color and quality will all make your prints look different.
By the way, recognizing /acknowledging this universal problem is an important step in your trip to making some art. All experienced Photogs go thru this. Its a never ending struggle. Just wait next it will be a $1,000 monitor that shows 100% SRGB, or even better Adobe RGB.

Having shot 8x10, 4x5, 35mm, and Digital, I can tell you that scanned 4x5 are a real pain. there is a large format look for sure, but in the time it takes to set up and shoot I could do a 4 shot pano with my 800e, at that point there is no real resolution difference. Also the dynamic range of digital is better.
most of my film friends now shoot digital. But there is always an adapter to put a dslr in the back of your 4x5. That could be the best of both worlds. At Least until you have to carry it ;)

Filters?
No, Wait for the new Canon or get the new Tammy 15-30

Yes, the Canon 16-35....printing large get the F4 (it tests sharper) shooting the night sky get the F2.8

Just to confuse the issue the Tokina AT-X 16-28 tests as sharp as the 16-35 F4, and it is a 2.8.....but filters are a pain

Yes Ken is right. I have used many old Nikon, and Tokina lenses. But here is the elephant in the room. You have a great camera, far better than what ken used when he came to these conclusions. It will show flaws that a D3 or D700 would not. Ken is a good source of information but there are more accurate testers out there. He tends to put enphase on his own opinion, and this bugs may Potogs on the net...http://www.dpreview.com/forums/post/55215186

Personally I consider him just one of many sources. Not the most trusted but a lots of information. DXO is far more accurate, and Tom Hogan is better, and more practical.

Red them all then hope you get a good sample of the lense.

As a photographer living in Las Vegas I can give you my perspective on most of these locations, I go to them several times a year.
The problem is, until you've been there you won't know if you agree with my opinions or not. So take all the advice that you get with a grain of salt.

The Grand Canyon, does not compare to some of the other locations on your trip, and can be a big waste of time. Having arranged trips for multiple photographers, I can tell you that everyone of them has agreed with the statement. Many of my photography friends have told me that they wished they dedicated less time to the Grand Canyon and more time to Southern Utah.

The Grand Canyon content to be crowded, and touristy.

If you're going to Flagstaff, you need to stop in Page. There is horseshoe Bend, and tons of canyons to visit on the Indian reservation. I recommend hooking up with my friend Lionel, He can take you to antelope Canyon at night!!!

The amount of things to see in southern Utah, and the Navajo nation, Is overwhelming. And somethings can't be rushed. And example of this is the "Subway" in Zion. It requires a permit, and an all day hike, but it's unbelievable.

I would recommend these books as a great guide for planning your trip.

800e and 14-24 is a great combo, and would be my recommendation. Dont forget a good tripod/head. Filters are expensive and hard to handle.

3 years ago I purchased a Nodal head, and switch over to primes 35mm, 58mm, 85mm. Now the 14-24 isn't used as often.

The D800 series are better cameras than the D750. But the advantages are really limited. So it's silly to say you should buy one over the other.

Personally I like the 800, mostly because of the button layout, how it brackets (5-v-9 frames), CF Cards, and the large file size. However, I print large (Bus and building wraps). If your prints are 24x36 and smaller, you should ask if it's worth the extra $$$.

One important issue that no one mentioned is computer requirements. If you use photoshop you will need tons of memory, and lots of storage. I spent $4,000 on my mac pro for the large D800 file stitching/processing. I can process the 24 mpixel files on my 3 year old lap top....
