The Sigma 24 I bought in mid-90's had full metal body too, with plastic aperture ring. But what made their lenses substandrd was not about plastic or metal, but the mechanical designs. For PKA mount design, the aperture mechanism was poorly design and lacked precision. There are also other minor problems like easy to wear materials (coating, rubber, aperture ring etc). But they might have improved since? I don't know. ===== Alan Chan http://www.pbase.com/wlachan __________________________________ Do you Yahoo!?
