I have found an old manual macro extention lens in perfect condition ,and just wandered how and if its going to fit and work with my D50.

A make/model or picture would really help..

Assuming it does fit, in all probability, none of the TTL functions will work.


OOPS... seems I misread the question.

You said extension LENS as opposed to extension TUBE. They are two different types of attachments.

An extension lens is a thin ring-like attachment that threads onto the glass (not camera mount) end of an existing lens. In that case its thread size needs to match the thread size of the lens it is mounted on. (Don't confuse that with the focal length of the lense, those are two differnt things). Typically they come in sets of three with diopter ratings like +1, +2 and +4.

An extension tube is an attachment that fits between the lens and camera body. In that case the lens needs to fit the tube and the tube fit the camera mount. In that case, depending on the tubes, you MIGHT have issues with f/stop and/or autofocus control.

I have found that all of my old nikkor and other nikon mount lenses work(i.e. I can take pictures) on my D70. But, the TTL lightmeter on the D70 does not work, so I have to manually select the F Stop and use trial and error on the exposure time to get a decent exposure.
