The recent thread of LLD sufferers looking for their own grails of glass showed up a surprising number of people using AI and AIS MF lenses. One danger of starting a thread like this is the fact that many of these great old lenses are very cheap on ebay and elsewhere and demand could be fostered by sharing too many in secrets. I must blame my own LLD in this area on Bjorn Rorslett (listening?) - even though I have to go completely manual on the D70 with them. BUT - so many of them are incredible gems - I remember the thrill of the first portraits with the 105/2.5 for example. So, you MF users - what are your favorites? Dont have to be Nikkors - other makes with adapters will do. 20/4, 28/2, 35/1.4, 50/2, 55/2.8 micro, 105/2.5, 135/2.8, 200/4 micro, 300/4.5 ED (not IF).
