My SLR camera damaged if I use a lens that is not the same brand?
I have a Nikon D40, and I've been looking for new targets the Amazon, I found a lot of good at a good price, but are not Nikkor lenses. Does it damage my camera?
There are a number of high-known companies do to adapt to the Nikon camera lenses, these include Tamron, Sigma, Tokina Vivitar and have been doing this for many years. So of course, the legendary Carl Zeiss including models to fit Nikon says http://photography.suite101.com/article.cfm/new_carl_zeiss_classic_lenses While The lens is made of a Nikon mount should not be a problem.
