Function of the Tamron Adaptall for Minolta AF

[georg_kern]

There is a Tamron Adaptall available to fit Minolta AF (please note:

I don't talk about the obvious MD-mount adaptor). It is clear that

you loose metering on the AF body (no aperture simulator), but what

about the automatic diaphragm? As the Minolta AF bodies close the

lens diaphragm via a mechanical connection with the lens (like in a

MF body, but different from the fully electronical system in Canon),

it should be possible to pre-set the aperture on the ring on the

manual-focus Tamron lens. The aperture should stay fully opened, and

only close down automatically when the picture is taken. In theory,

flash-TTL photography should be able without restrictions. Any

experiences?

 

Thanks in advance! Georg.

I owened the Contax mount Adaptall adapter. It did have a small mechanism that connected the camera shutter mechanism to the Tamron lens shutter mechanism. So I would assume that this also holds true for the Maxxum bodies. I would assume that even DOF preview should also work. Hope this helps but somebody who had a Tamron adapter on a Maxxum body might be a better help.
