90 210 and 300 here, and would like something around 150 ... the 300 is portraits only and the 90 is wide angle so the 210 is the equiv of something about 80-100 on a 35mm camera a 150 would be about a 50mm equiv to 35mm.

A neat lens to see if you can find would be one of the schneider convertibles, or see if a buddy will let you borrow something before committing to one.
