Hi guys / gals, I just finally, finally got myself a Mamiya 7, something I have been wanting to shoot with for about a decade now. Anyways, overall most everything seems to work just great, manual mode works fine, AEL works fine, but as soon as I try to use aperture priority, the viewfinder just blinks "LT" at me constantly regardless of aperture or ISO setting even in very bright outdoor conditions. I thought maybe the battery was bad so I went and bought another to test it out but it was the same response. I tried cleaning the lens and body gold contacts carefully but still the same response. I'm trying to figure out if this is going to be indicative of a larger issue to come and if I should look into returning it and continue shopping for another setup. Any thoughts?
