It's not. The one I bought about a month ago only has 9,600 shutter count. Shot a wedding with it and while the controls are a little different than the D750, it's only a little. I had planned to shoot the wedding with a D750 and D600. When I started shooting the D750's hotshoe failed so I grabbed the D850, which I'd only had for a week at that point. If you've never shot a wedding, it's rather intense in regards to equipment usage. Close to non-stop shooting for hours. With the D750 and D600, they are so similar that I rarely know which one I'm using. Shooting a wedding with the D850 and D600 the experience was similar, though a little more pronounced. But really, it's not a factor. So what if the ISO button is on top instead of down the left side? It's not like I change ISO much during a wedding.

And I found a used D750 with only 2,800 clicks on the shutter. Amazing. I guess it was owned by the proverbial little old lady who only drove it to church on Sundays. Trading in my old D750 as is, and a couple of lenses I never use and my out of pocket is just a few hundred - and I end up with a like new D750.

The only problem I'm finding is that I'm finding that there is almost zero market for my D600. It's in very good condition but the used camera places didn't want it and looking on Ebay the few on there have close to zero bids on them. I know the D600 had problems when new but mine was repaired by Nikon and zero problems since. So, I don't know. Might donate it to a school. It also raises the possibility that in a few years when I go to buy a used Z8 there won't be any market for the D750 anymore, but, as someone recently said, "I'll burn that bridge when I come to it."

Would I be better off with 2 D850's? It's open to debate. I only shoot about 10 weddings a year. For portrait work I only use one body. And for travel I really like the lower weight of the D750. So yeah, the model is at least partly obsolete but it still produces some of the best image quality with one of the largest dynamic range.

I am happy that you have found a solution that works for you. Hopefully you will be able to find a home for your D600. I bought a used D610 when I first decided to try full frame, but decided after about two days that there was no way it was going to work for me. The list of reasons was quite long. Fortunately, I was able to trade it for a D810, which worked out much better. Unfortunately, a lot of retailers have back rooms stacked to the ceiling right now with mirror-box cameras that they have taken in trade for mirrorless cameras. Several stores in Texas are no longer accepting them in trade or purchasing them at all. It's possible that the market might change, but that might take a while. Your best option might be to find a nice compact lens and take advantage of the D600's reduced size forf a discrete "project camera," or perhaps for capturing candid shots at weddings.

While I still have and use the D810, my main cameras now are D500s and D850s. They have some control refinements that make them much nicer to shoot, and I do not miss the pop-up flash anywhere near as much as I thought. I've got a couple of SB-400s that I can quickly pull out if necessary. They are stronger, wider, and don't create a shadow from being too close to the lens when using shorter focal lengths, even with their low-profile design.

Anyway...have fun with your new camera.

Little old lady on Sundays, LOL. A great euphemism for the UHH community who regularly posts for-sale cameras with sub 10K shutter counts. Personally, I shoot a pair of Canon 5DIIIs (full-frame, 22MP). I bought both lightly used nearly 10 years ago. Both report over 120K shutter usage. I thought I'd get into event shooting, but never did beyond the early years. Two identical cameras is a nice luxury, either shooting both together or keeping different lenses mounted around the house to grab for immediate needs and purposes. But mostly, I have more cameras than I can shoot, with also a Sony mirrorless and a film body.

Regarding resale value and DSLR market conditions, I'm a firm believer in unloading unused equipment as soon as the replace body has arrived. Every day one holds onto unused equipment is another day it loses more value. Only you can decide if the shooting features of the D750 justify getting another one (or a repair) and dumping the D600. Or, just hold the D600 as secondary and travel, possibly until it presents a problem and the issue is revisited. Rereading, it seems you've already grabbed another D750?

These pro-grade cameras are built to lost. Once the sensors reached the 20 to 24MP standard, we had all the 'camera' the vast majority of us will ever need. Some of us in the UHH community actually bought the final camera we'd ever need, although few in the community seem to think that way until they've wasted money on still another one.

Just some personal thoughts on the question of this thread. Mirrorless bodies are superior in their features, but the images are identical, just like most digital sensors since we reached that 20MP threshold. Good shooting ...
