I have Vivitar Series 1 70-210mm 3.5 lense. Can I get it AI'd to use on my N70? I inherited a Nikon with the 50mm f/2 lense and the lense above. Thanks. George PS Anyone know how to use a Exposure Meter Type PR-1 by GE? I would greatly appreciate it. "And the high vault of Heaven looks far away and cold." - Bruce Cockburn's "Get Up, Jonah"
