I tried to adapt Nikon lenses to Fuji. The adapter is made well but I did not have the ability to use autofocus. Also, consider whether you have a G type lens, without aperture control It might make a difference as to which adapter you buy. If you don’t have an aperture control on your lens, it will be harder to use aperture priority as well. My Nikon lenses all have aperture controls but I found the weight distribution to be off and no autofocus. I just checked the Fotodiox website to and am not seeing an adapter that will keep the autofocus ability for Nikon to Fuji. If you have a Fuji camera and want to save some older Nikon lenses, it might be worth considering but call Fotodiox or a reputable store first.

The answer to your specific question is that this is a good time to buy a mirrorless camera. There is a lot of good quality used equipment on the market.

You have not made it clear what type of photography you intend to pursue. That will affect lens choices and, to some extent, sensor size. If you buy lenses that are not designed for full-frame, it will affect your future decisions. For example, if you are going to take portraits, a good 85 or 105 prime on a full frame camera is a great piece of gear. Wildlife requires different equipment. We can help you more if we know what you intend to be doing.

I still use Nikon equipment and have a DSLR, not the newer Z series. That decision was made because I have old, but excellent Nkon lenses. I don’t think that adapters are the way to go, particularly if you will lose any electronic capabilities.

If you are “starting out”mirrorless is fine but a lot depends upon what you intend to shoot and the quality of available lenses. You need to consider sensor size-APC, full frame to other, but any camera from Sony, Nikon or Canon will be good. I am not a big fan of Fuji mirrorless, but am in the minority. Including in this thread. I have had two Fuji’s and several lenses. I consistently have not found them to be as good as my Nikon gear. (Nothing matches Leica lenses but a Leica system is a huge expense.)

You might call Issac at Southern Photo in Miami. Very reliable repairs shop. See what he suggests.

If you want a D750, I suggest that you buy a used one from a reputable source with a good return policy. If your Nikon lenses are not designed for full frame cameras, then you will not be able to use them. All of my Nikon lenses were from the film days and are razor sharp. I never heard of such things as sample variation at the time.

I bought a used D750 and use it with old Nikon lenses. It is a great camera and was very reasonably priced at Adorama. If you have Nikon lenses, they probably will work on the D750. I think that the commentators on this site have good insights.

I never used Canon equipment and have basis to compare. I have been using Nikon and Leica cameras for a long time - over forty years. I also have a complete Fuji mirrorless system. Candidly, I don’t care for the output of the Fuji’s. So much for internet reviews.

I really like Lightroom Classic. After the trial period, I am using it on a subscription basis, which bundles Photoshop and Cloud Services. There is a big learning curve, at least for me, but they have great on-line remote support. I also am going to take classes offered by the Leica Store in Coral Gables Florida. I am amazed what you can do with Lightroom classic and photoshop and it is easy to go back and forth. Lightroom Classic is great for editing and organizing your pictures.

I am curious whether the Nikon 24-120mm is a good lens. I had an older version with variable aperture and it was sub-par at best. I am thinking about buying that or the 28-300 for use with a D750. Both seem a little slow. I have a 35-70 f2,8, a 105 f2.8 macro and a 80-209 f2.8. Great lenses but heavy. Most of the pictures that I take are of people.

Nikon 85 mm 1.4 D and Leica Type 109 (24-70).

I am sticking with what I have. Thanks to all who responded.

I appreciate your thoughts. I am not stressing about this. I just was curious. I really like the D750 but before I kept it during the return period, I wanted to make sure that I made the right purchase. I do have a full Fuji mirrorless system as well that I am going to sell (XT2, 23, 27, 50 and 55-200). I travelled to Portugal before Covid and really did not like the pictures it produced despite the great reviews on the internet. I have been shooting since the 60’s and like to photograph people. The feature that interested me in the newer Nikon cameras is the eye follow focus. There always will be new technology but I did fine with my fully manual Leica M6, which I never should have sold. I think that I will keep the D750 and use my Leica Type 109 for walk around shots. My Nikon lenses are razor sharp, but are old and heavy (20 f2.8 , 35-70 f2,8, 85 1.4D, 105 f2.8 macro, and 80-200 f 2.8 push-pull version). I have travelled to many places in Europe, Central America and Asia and my Nikons and Leica never failed me, particularly using my M6 on a hike in Cambodia. I am going to stick with the old lenses and not make the same mistake as when I sold the M6. Thanks. I think that I am going to place my efforts on learning more about Lightroom and Photoshop since I no longer have a darkroom or convenient access to a great photo lab to blow up film photographs.

I have a concern that some of the newer DSLR’s and Mirrorless cameras might be using new forms of memory cards that might not be compatible with my current equipment. I just bought a used D750 that can use the memory cards that I have and my old lenses but the Nikon Z series, for example, the seems to use completely different memory cards. I bought the D750 in order to use some old Nikon lenses that are great. I know that I can get an adapter for the Z series but I believe that I will have to buy new cards and a card reader. Can someone explain the differences in the cards and what is on the horizon? The reason that I am asking is that I still am in the return period for the used D750. Would I be better off returning it and selling my old Nikon equipment?

I wish all of you a Happy and Healthy New Year. It is interesting to read what features are important to each of you but, in candor, my favorite cameras all were Nikon film cameras and my Leica M6. I have been taking pictures for many years and never heard of focus stacking until I read this thread. I bought a used D750 at a good price from Adorama in order to use my old Nikon lenses. My walk-around camera is a Leica Type 109. While not on the level of an M6, it takes really nice pictures. I am not ready to trade up to a D780 or D850 but who knows. In any event, I have enjoyed reading everyone’s comments and look forward to traveling again. Best to all. Stay safe.

I am not sure that it is worth it to trade a D75O for the D780. Oddly enough, I faced a similar decision and just bought a used D750 at a very good price. I think that it is a terrific camera. You may take a fairly large loss if you trade it w/o much gain. I looked at a Z6ii and decided to go for a used D750. The D850 is a great camera but it is heavier. Do you need such large files? The D780, D850 and the Z cameras do not have built in flashes, if that is important to you. Nikon claims that removal of the flash was for weather sealing purposes. If you use a flash, you will have to buy one and carry that around as well.

While this might help, I also have a Fuji XT2 with several lenses. It certainly is lighter but I like the quality of the Nikon pictures better.

Bottom line is what is important: Newer model, features, larger files or weight. Personally, I think that you will be fine with the D750.

I have a Leica Type 109 and a Fuji XT2 with the 23, 27, 50 and the 50-200 Both cameras are very good. Personally, I like the Leica for walking around but you can get the same camera branded as Panasonic for much less than the Leica. There is a newer version of the Type 109-the D Lux.

You really can’t go wrong. The main issue to me with the Fuji X 100 series is that the focal lens is fixed. Depends what you shoot. The new Fuji x100 series got very good reviews. I am not enamored with the Fuji system but I am I’m the minority, My XT2 with the 23 is light and versatile.

I recently bought a used D75O (made in Thailand) so that I could use some twenty to thirty year old Nikon lenses. The camera is great and I would not have looked where it was made but fir this string. I would be surprised and disappointed if Nikon went out of business. I have owned Nikon cameras for over 40 years. I also have a lot of Fuji mirrorless gear but I think that the Nikon equipment is better. I still think that film cameras are better but that’s just me. BTW the Fuji and Nikon equipment are excellent
