Can I use a Full frame camera and a DX lens? Im thinking about buying a new FX camera but have some DX lenses. Will I be able to use them?

Yes, For example, my Nikon D700 is an FX camera. I can use a DX lens on it. The camera will only use a portion of the sensor.

If I use a Nikkor DX lens, the camera will automatically do the cropping function. If not, I have to let it know.

This same subject has been discussed RECENTLY on several occasions. Use UHH's excellent Search function (at the top of this page) and search on "fx camera with dx lens" and "dx camera with fx lens" and read page after page of info. [Bob always trumps my answer...Lol]

Yes, you can use them.

Sell your DX lenses. If nothing else, buy a used or refurbished 28-300mm. For your first really good full frame lens, I'd recommend the Nikkor 24-70mm f2.8.

You'd have to decide whether or not the money you could get would be worth getting rid of the lenses. They're still usable until replaced.

Don't hesitate with the FX purchase. The lenses you have will work, and you can eventually sell them and buy FX lenses. Used and refurb will save you money. I bought a Nikon 35-70mm f/2.8 on ebay, and it's fantastic. Very sharp.

Thanks to all.

Since you are using Nikon terminology and assuming you are using Nikon camera and lens, the answer would be "yes". AFAIK, all FX Nikon cameras have a "DX mode", where they detect when a DX lens is attached and automatically utilize only a portion of the image sensor equivalent to a DX sensor. Be aware that this is a significant "waste" of FX resolution potential and capability. For example, with a 24MP FX camera, in DX mode it's like shooting with a 10MP camera instead. That's a significant difference from the 24MP some of the DX cameras offer.

If, on the other hand, you are using some other camera system, besides Nikon, the answer might be "no".

For example, Canon "EF-S" lenses cannot even be fitted to Canon full frame cameras. Those lenses use a variation of the EF mount that's designed to prevent them being attached to the FF camera.

Third party lenses, such as those from Tokina, Sigma and Tamron, for use on Canon don't have that same physical limitation. They simply use the same EF bayonet mount, even with their "crop only" lenses. Images will typically show a little to a lot of vignetting, though.

And, you have to be a little careful. Some "crop only" lenses have what's called a "retro focus" design, where some of the rear elements of the lens can protrude inside the camera itself at certain zoom and focus settings. This is fine with crop sensor cameras that use a smaller mirror, but it can interfere with and damage the larger mirror in full frame cameras.

I am not familiar enough with it to say anything about the Sony system, who also make both crop sensor and full frame cameras. Pentax currently only makes APS-C crop (thought there are rumors a FF camera is coming soon). Olympus only makes so-called four/thirds sensor cameras, which are even smaller than APS-C (Nikon, Canon and Pentax). The only other manufacturer I know of making both crop and FF right now is Leica.
