i'd try the 75mm heliar first, then upgrade to another lens if desired. you can get one in mint condition for $250-300 on ebay.
560 grams.
large and the long focus throw is a long slog around the barrel....I never did get the hang of focus on a moving subject...make them sit still and use a tripod, traded it after two years for an SWC, best move for me.
