Took a chance on a Konica Autoreflex T4 for fairly cheap, its in decent shape however the shutter seems to fire at the same speed from 1/30 on up. The camera does not currently have a battery and I was under the impression that it is only needed for the meter but I was wondering if I was incorrect about that? If it isn’t the battery I was wondering if someone has ran into this problem before and could tell me if it’s and easy DIY fix or if I should send it into a shop and have them take care of it? Thanks.
