Everybody wants to save money and see if they can use their old lenses with a new DSLR body. You will find that it's not worth it. There are adapter rings that will allow them to fit, but everything you do will be manual. You will have to manually select an f/stop, shutter speed, and you will have to manually focus. DSLR's don't have a split focus screen in the viewfinder, but you can have one installed in some camera bodies so that they focus like the old SLR. Trying to manual focus without one is close to impossible. I recommend that you buy your DSLR and choose one good lens designed for that body so that you can experience how nice the new stuff is compared to the old camera system you are already acquainted with.

This is an easy to answer question. I have some of the same lenses as you have, the 50 1.4, the 85 1.8 and 50 mm El. Forget about buying a Nikon camera if you want to use your old glass. If you want full frame sensor in a camera that will allow you to easily use your old glass with great results you have to get a Sony A7. That is the way to go. I have lot of old glass and have tried to use it on my crop sensor and full frame Nikon Dslr. The problem is that focusing is difficult. You have to to use live view for accurate focusing and that takes way to long time to be useful in most cases. With a mirrorless camera like the Sony A7 line (I have a A7r) you can configure your camera once and for all so that you only need to press one button to manual focus accurately and quickly. It makes it just as easy to use manual focus lenses as it was in the old days. I guarantee this is by far the best option if you want to continue using your manual lenses. If you buy the newest models Sony A7II or A7rII then you will also get a camera that that has image stabilizing that works with your old glass. But the original Sony A7, A7s or A7r also work perfectly with your old glass, they just do not have the stabilizing feature. You will need to buy an adapter but that will cost you less then $40 for a good one. If you need further assistance or info about this send me private msg. There are many other options but those Sony cameras are the only with full frame sensors. I was skeptic about the Sony cameras until I tried but it only took a few test shots after I configured the camera (it is just about deciding to use one button for focus peaking) to get me convinced that this is the way to go with old Nikkor glass.
