I was looking for a good bird watching lens and have found lots of 200mm 3.5 PE&QF lenses up for sale but I know nothing about either except they appear to predate the MD mount and the QF has styling that would indicate it may be newer. Anyone know more ?
NOT really as I am also always read about them so that when I am actually ready for the purchsse I can actually buy the right stuff. But i have read a quiet a bit about them on Testfreaks
