Hi, It is common to many people, that one can use lenses from other brand manufacturers on one's dSLR. This can be done through the use of an adapter. I have two medium format lenses that I would be happy to use on my Nikon D50 dSLR. To do this, I need an adapter. Novoflex adapters have built a reputation for their quality, (not on the very cheap sideeither). Other adapters can be found for a very good price on e-bay. (I think i'll go for the adapters sold on e-bay) When one thinks about using an adapter, one wishes to loss as little performance as possible when using such an adapter. I spoke to a man in Novoflex, and he said that the cheaper models from Nikon will not be able to meter when using the adapter. However, he said that most Canon EOS dSLR camera bodies shouldn't have any problem. Have you used an adapter with your dSLR ?? How did the metering go ?? Any comments or ideas are welcome!! Thank you very much, kind regards, igmolinav.
