Sigma lens and Sony

[PWhite214]

The total strangeness of Sigma's lenses on Sony/KM cameras continues to astound me.

I have a Sigma 300mm f4 Prime and a 500mm f7.2. Both lenses work great on my Sony a700. Both lenses work great on my Dynax 9. Neither lens works on my Maxxum 7.

I plan, if I have batteries for them, to check operability on the Maxxum 5 and any other old bodies I have laying around.

Just venting a bit, and a warning if you use older cameras.
