The only difference is the design (appearance) of the lens body and probably one of the most beautifully finished Leitz lenses. There are several variations and the earliest one (this lens was started in 1960) is known to be the prettiest. The performance of the smaller newer one is supposed to be a little better than the old one, though their lens configuration is 4 groups 5 pieces. But newer one is not as beautiful as the old one. Like you stated, the old lens is heavy, so the best way to use is to attatch it directly to a tripod. Junichi Uenohata
