The hazards to the workers in the smelters became too apparant to tolerate any more. The Canon folks assured me that as they figured out optical glasses that don't use toxic materials they would re-issue a similar lens; with the good success of the Nikon 200 F2 you can bet that Canon will bring out a revised version fairly soon. 0.02 Don don.dory@gmail.com On 12/23/06, Brian Reid <reid@mejac.palo-alto.ca.us> wrote: > > > > Bonus benefit--the Canon EF 200mm f/1.8L.
