Take the lens with you when you visit your local camera store.

No direct experience with that combo.

I've seen the odd mention of compatibilty problems between the 7D and
some Sigma lenses. I suggest you post the same message in the K-M SLR
forum at http://forums.dpreview.com/forums/forum.asp?forum=1035 for
which you will have to register with dpreview (no big deal). Likewise
in the yahoo forum at http://groups.yahoo.com/group/Minolta/ .

I would bet that if it works well with the 7, it will work fine with the 7D.

Find a local store that has one in stock (or a local photog), drag your
lens over and test it. Be sure to test it with AS off, and with AS on.

I have the 7D, BTW, and it was an effortless transition from the Maxxum 9.

Cheers,
Alan.

Since Minolta's AF motor is in the body, the gear ratios and resistance
in the lens are responsible for how fast or slow AF is achieved.

The Maxxum 80-200 f/2.8 G autofocuses very fast on the Maxxum 9 and 7D.
I'm sure there are faster, but end to end AF is about 1/4 second by my
reckoning.

IAC, I usually manually focus, which is too 'quick and slick' on this
lens. I'd rather a longer turn with more tactile resistance. (The 100
f/2.8 macro is great in this respect).

Cheers,
Alan
