Hey guys,

I just bought a used macro lens and I just realized that I can only take photos in manual mode because in every other mode, the camera reads "Lens Not Attached".

I have a Nikon D3200 DSLR. All the normal lens that came with the camera work fine on every mode, but this one only works in manual mode.

Is this normal or did I get a broken lens?

MF would usually stand for manual focus. Gnarling is usually found on older lenses, which would make sense if it were manual focus only. How old is it and where did you get it?

Your camera requires a motor in the lens for auto focus. That lens doesn't have one. Manual will work fine though.

I think I get it now. The fact that the lens is only manual focus eliminates all the other auto modes on the camera because the camera needs to have that connection to the motor in order to enable those. Sound correct?

By the way, I got it on eBay for what I think is a good price. It takes great pictures on manual mode, I was just wondering if this was the only mode I would have available, which is fine.

Nikon cameras have focusing motors in the lenses, Canon in the body. At least that's the way it used to be, there are probably some exceptions. That's one reason why lenses come in "Nikon" or "Canon" mount. I'm not sure what metering functions may or may not work, Misled or someone else might know.

My understanding is that as of 1987, Canon slrs / dslrs do not have a focus motor in the body, and all Canon EF lenses have a focus motor. I believe EF stands for Electro-Focus indicating as such.

Nikon pro model cameras and some older DSLR's have AF motors in the body. The camera should still meter and you should also be able to adjust the f-stop from the body. The only thing you should loose is the auto focus.

For macro work you only want to shoot in manual mode anyways. You win ;)

Thank you guys. I just wanted to know if the lens was broken or if this was to be expected.
