Digital cameras that will accept SLR long lens?

If your 35mm cameras are Nikon - the lenses will fiot Nokon digital.

If your lenses are Canon EOS (EF) then they will fit Canon digital.

If your lenses are Canon FD or FL they will not fit any digital

If they are 42mm screw fit they won't fit any digital.

If they are Pentax K - I think (not sure!) they will fit Pentax digital.

What you want to look for is a DSLR (Digital SLR) that is the same Brand or at least the same Lens mount as the Lens that you have. You did not mention the name of the brand of camera you were using for the 35 mm SLR. We have a Pentex DSLR and it does take the older lenses but the only thing is that the auto focus may not work if the lens is too old.

As far as getting a "Reasonable Price" for a compatible DSLR I would research for the brand of the Camera those lens were for and or the mount of the lens. Then go and check your local Craigslist.org and click on photo/video and in the search box type in the camera brand's name (like Nikon or Canon). Here is the search result for my area's search for the word "Lens":

You don't need the latest or the greatest, just one that works and is (I would say) at least 6 Megapixel or better. You might even get a good deal with a couple of extras with it for cheap.

Lastly, here is a site that breaks down the different lens mounts for you:

Hope all that gives you the info you need.

Depends on the brand.

If they are Nikon, you can most likely use the older lenses. But if it is a Canon, and if it is a FD lens (made prior to the mid-'80s), then you are out of luck as new Canon DSLRs will only work with EF lenses.

Or if you have a Nikon and do not want to buy a DSLR, you can buy a Nikon 1 with a FT-1 adapter. This will allow you to use the F-mount Nikon lenses. However, you are still near the range of buying a DSLR with the cost of a Nikon 1 and FT-1 adapter.

And the lenses will not autofocus (if they are AF lenses). But you can put the camera into manual exposure and manual focus and the lenses will probably work.

It used to be that I did not recommend a Nikon 1, as they were pretty expensive. But you can buy a Nikon 1 V1 these days for $299 new, and at that price, they are an attractive alternative to a DSLR.

The original price of the V1 was $900, which was way too expensive. But when the price dropped to $299, I bought one, and I am very impressed with it. It is absolutely the best camera you can buy for $299.

The FT-1 adapter costs $200 though, so you are at $500, which is approaching the cost of an entry-level Nikon DSLR.

But I have enough lenses to justify the adapter. I own a Nikon 80-200mm f/2.8 and Tokina 80-400mm f4/5.6. Although both lenses are AF, meaning I need to manually focus them, they turn the Nikon V1 into an excellent birding camera.

With a 2.7 crop factor, the equivalent focal length for my 80-200 is 540mm - AT f/2.8, as there is no loss of light when using the FT-1 adapter. And the Tokina... it is an equivalent of 1080mm @ f/5.6. Great for birding.

Nikon did away with the aperture ring on the lens and went with the command dial on the digital camera, the lens could be set to the optimal aperture and then use command dial to open her up ( from extensive open to the max. and each little thing in between). this methodology grow to be use properly earlier the D40 or D80. push aside the above that is not maximum appropriate, i grow to be going via what I examine on the internet ( i assume I shouldn't have faith 0.5 what I examine on the internet) i'm drained so i wish that is clever. notice the digital camera meter on the D40 or the D80 won't artwork with instruction manual concentration lens, you would be wanting a D200, D2Hs, D2Xs or the recent D300, or D3 for the metering.

If you know the brands of the old cameras, than get an adapter that fits the new camera and fits lens from the old camera. If it is the same brand, it might be able to fit. If it's not than their are adapters like a leica to canon adapter or a nikon to canon adapter.

Are we supposed to guess the make and models of these cameras and lenses? There are many SLR lenses that can be used on a DSLR. There are also many that aren't worth the effort. Needs more info.

To my knowledge only Pentax lenses from the film days can be used on thier current DSLR cameras.

Maybe. What cameras do you have?
