I have a lot more than ten Nikkormats/Nikomats but I also have many standard Nikkors. if I can remember all of them they are: two 50/2 H, two 50/2 HC, three 50/2 'K', one 50/1 AI, two first generation 50/1.8 AI, one late 50/1.8 AI, one 50/1.4 S pointy prong, one 50/1.4 S round prong, one 50/1.4 SC, one 50/1.4 early 'K', one 50/1.4 late 'K', one 50/1.4 AI and one 50/1.4 AIS. In addition to these I have one 45/2.8 GN C, eleven 55/3.5s and one 55/2.8. I read earlier today that Kodak has discontinued all color slide film so if you want to put some Ektachrome in those Nikkormats, get it now. You don't say which Nikkormats you have. Some standard lenses can probably be bought for a good price if they are attached to non-working camera bodies. There are still 50/1.8 Series E Nikon lenses available for reasonable prices and also look for some 55/3.5 lenses.
