Will all the nikon digital slr lenses work with all new cameras?

All your DX lenses will work with every Nikon dSLR except the D3. The D3 is the first full frame sensor dSLR and there are 5 new FX lenses that will be coming out at the same time that one does. The D40 won’t take any of the older manual focus lenses. Other than those few issues, everything should work just fine. Check out http://www.kenrockwell.com for all the specs on the new cameras and lenses.

Maybe. I would break it down this way:

D70 / D70s. Yes, no problem.

D80, yes, no problem.

D200, yes, no problem
D2x, yes no problem
D300, yes no problem

D40 or D40x–will work and meter, might not autofocus unless the lens is an AF-S lens or a Sigma HSM lens.

D3–yes. The D3 should automatically sense if it’s a full-frame lens or a DX lens and adjust accordingly. It’s a pretty smart camera!

yes they are nikon fittings otherwise they would not fit your d50.

The quick answer is yes, all of the current Nikon lenses you have will work.

But … there’s a recent change now. The new D3 that was announced has a full sized sensor, not the smaller one that all the other Nikon SLRs have. So now the rules have changed a little.

The first answer for that camera is also yes but with a difference. All of the Nikon DX lenses were designed for the smaller sensor that all the SLRs are using all the way up to the D300 which was also announced recently. When it comes to the D3 however, while the DX lenses work there too, they only work in a crop mode which will give you a 5 megapixel image instead of a 12 megapixel one. For the D3 you would want to use regular lenses designed for 35mm, basically lenses that are not DX designated.

Now that said, Nikon SLRs accept any lens that was made after 1977. That is to say you can attach them to the camera and you will be able to take pictures and get exposures that are accurate. However many of the early ones do not have autofocus so you’re into focussing manually of course. What is encouraging in this guarantee too is that these are all lenses designed for 35mm so they will also work perfectly with the new D3.

So, any lens you currently have that works on your D50 will work perfectly the same way on all the newer Nikon SLRs. But, if you have a DX lens and you wish to use it on the new D3, you’ll have to settle for cropped 5 megapixel images.

This change in their professional camera sensor now also opens up a new question, basically … what kinds of lenses should I buy now? The odds are even that when a replacement for the new D300 is announced it might have the larger sensor too though I get the feeling at the moment that Nikon might reserve that only for the professional line.

So while you’re welcome to buy any camera they offer at the moment and while you are able to continue to use all your lenses as before, if you later decide to purchase a new lens you’re going to have to ask yourself whether you will ever buy a professional body later on. If the answer is yes, the next lens should not be a DX, it should instead be a regular Nikon lens. If the answer is no, then you’ll be able to use the lenses you have forever as you continue to upgrade your SLR every so often.

I hope that helps.
