Hopefully someone can clear up this grey area for me. I have a chance to get an 210mm Sironar N for a really good price. The lens is labeled as a Sironar N. It is multi-coated as it has the letters MC on the barrel as well. I don't have it in front of me, otherwise I would include the serial number too. Roughly from the mid 80 is my guess from the multi coated designation.
Anyways to my question. I've been told that the change from the Sironar N to the Apo-Sironar N was a change in name only. Is this true? Does anyone have a catalog or brochure to compare the specs?
Thanks,
DrPhil
