[glindakc]

i have a sony alpha100 with a minolta mount. i found some nice minolta lenses from the 70's, but they don't fit. did the mount standard change in the last 30 years? is there an adapter for this?

Yes the mount changed in the 80's with the introduction Minolta Dynax/Maxxum AF system. There are adapters out there to adapt your old MD/MC lenses to AF bodies, but with the following limitations I got from gadgetinfinity's website:

" 1. Autofocus (AF) is not available;
2. Stop-down metering is used. Spot metering mode does not work properly.
3. Although it is possible to use the A (aperture-priority AE) mode in auto exposure, the aperture display is not available.
4. In the P (Program AE), or S (Shutter speed-priority AE) mode, the shutter releases, but the auto exposure control does not work.
5. The distance scale on the Minolta MD/MC lenses may not indicate the actual distance. Always use the viewfinder for focusing.
6. Since the Sony Alpha and Konica Minolta DSLR cannot recognize the MD/MC lenses, please unlock the shutter after mounting the MD/MC lens on the Alpha system."
