New member here. What is a fair price ( both to buyer and seller ) for the following LTM lenses: 1954 red scale Elmar 50/3.5 with Valoo sunshade/diaphragm actuating ring. Caps. 1957 Elmar 50/2.8. Caps. 195? Konishiroku collapsable Hexar 50/3.5 ( allegedly very rare ) All lenses are EXC+ ( and I rate very conservatively ).
