Can you use a Minolta MD lens in a Minolta SRT 101?

[Vsanzbajo]

I have a MD lens that I want to use with my SRT. Is that possible?

 

[zk-cessnaguy]

Yes.
Same mount.

MD lenses will work with any Minolta manual-focus SLR.

MC lenses will too with the loss of Program and Shutter Priority modes on the few models having those modes.

An interesting excursus about the various generations of the Minolta SR mount:

As far as I understand, MC lenses will work in principle very well in Program and Shutter Priority modes.

What happens is that if the lens is not closed at its minimum aperture, the Program or Shutter Priority modes will not be able to use all the apertures available.
So if you want to use not beyond f/11 a lens, and also a MD lens, which closes up to f/22, you just set the aperture to f/11 and the exposure will be "correct" anyway. The camera will use shorter shutter speeds instead of closing the aperture. You may obviously run short of shutter speeds in bright light with fast film.

X-700 (and XD-7 I suppose) have a green P in the viewfinder telling you are using the camera in Program mode. If the lens is at its minimum aperture, the P is lighted. If the lens is not at its minimum aperture, the P is blinking. MD lenses have a pin telling the camera which the minimum lens aperture is, MC don't have it and so this feature does not work.

I've never done tests myself (all my lenses but one are MD and I basically never use Program) but I do suppose that one can use Program with MC lenses without problems.

PS The speed of the diaphragm blades cause a problem, see link above.

 

[Noam]

I have a Minolta SRT 101 and use only MD lenses.

The MC lack the lug on the apeture ring to signal the camera that the apeture is set to f22 or max number/min apeture, P and S won't work without the lug.
Not all MD lenses have the ring lock.You have make sure it doesn't move.
