As a new user of Hasselblad equipment, trying to judiciously add to the kit, I am wondering why there is so much difference in pricing with the older chrome and newer black 250mm lenses. The lens addition would be for a 500 C/M kit which currently includes a 60mm, 80mm and 150mm. In 35mm I'm fond of a Tamron SP 180mm f2.5 and am thinking the 250, in Hasselblad, would come close to the same look. There is a budget and I do use lens hoods. Any compelling reason to not buy the chrome lens? Bill Barber
