I have a Minolta XG-7 and I was wondering if Minolta made a Digital Camera that I could use my lens on?

I would like to use my different lens on a Digital Camera to get the good pictures I get with my old XG-7

No, and they're not going to.
They were bought out by Konica and Konica-Minolta recently announce that they were quitting the camera business entirely.

If you want to get good digital pictures, use one of the solutions previously described. If you want really good pictures, keep using your XG-7 and film.

The new Sony DSLR uses minolta lenses. Found this out three months after I sold my lens at a garage sale.

The short answer is 'yes', you can buy a MD/MC to Maxxum converter (approx $100) and use it on a Sony A100, Maxxum 5D, or Maxxum 7D DSLR.

but there is an extra piece of glass inside, which allows the lens to be focused to infinty that adds a 1.2x crop factor in addition to the normal 1.5x crop factor of the APS sized sensor. (1.2 x 1.5 = 1.8 total crop factor).

but its probably not worth it unless you have alot of money invested in the old manual focus lenses.

No. Minolta, like the Canon, change their lens mount when they went to autofocus.

The Minolta XG-7 is a manual focus 35mm film SLR. The lenses that you have for this camera won't work on any Digital SLR camera for all intents and purposes. Althought there are convertors, you'll get unsatisfactory results using them.

I was a big Minolta fan. I loved my XG-1 and X-700. The Minolta glass was of very good quality for a consumer camera system.

I moved to Canon for my Digital SLR. My decision was based on the touch and feel of the camera (300D Rebel) and also on the fact that Canon has 100% control over all components because they make all of it. Canon also owns the DSLR market, outselling the closest competitor better than 2:1.

I still use film and I purchased a used Canon AF body at a very reasonable price so I could use my lenses on both digital and film bodies.

Minolta is NOT anymore in camera (35mm or digital) business. They are ...history ... ;-(
