Hi all; A little while back I greeted you all, with my 1st RF since decades ago. just a little update/conversation So the Yashica Lynx shutter speeds are pretty close. almost perfect, 1s thru 1/30, a little wee bit slow at 1/60, and then: 125 = about 100 250 = 166 500 =285 <- so I have a 250 setting haha. Used a phototransistor, Oscope. flashlight pointed into the lens, apeture mostly wide open. works real neat just happend to have an old RC propeller tachometer, the case was perfect with its hood for the phototransistor. today I found a Yashica GS 35 electro ($20) and a Canonet Ql 19 I think it is. Will see/get the Canonet tonight, Yashica is in the mail. so thats whats going on over here, hope you all have a great RF day.
