Yes the MD Zoom 70-210 f4 is the lens to go. It is optically identical to the Minolta AF 70-210 f4 beercan.
Make sure to get the hood with it.
Some Minolta enthusiasts prefer the MD Zoom 75-210 f4.5 and say it is a tad sharper. I own both and can tell you that my examples are nearly equal concerning sharpness, but I wood choose the f4 for better focusing.
