I have searched this, and have found nothing of any use so sorry if this is a repost.
I have been researching lens adaptors/mounts so I can use my 55-200mm Sigma (for Nikon) lens on my Canon EOS 550D (t2i). I have found various different options, but the price difference is just ridiculous!
Has anyone on NS used an adaptor ring and would recommend one? Or tell me why there might be such a drastic price difference as I can't figure it out.
Thanks in advance, and sorry for the long post
