I just bought my first 35mm SLR, a Nikon FA, and am having some trouble. Even after replacing the dead batteries, the shutter release button occasionally won't trip the shutter unless the camera is in Manual mode. Experimenting with the camera unloaded, I can't figure out whether something is causing this to happen or if it's just random. Furthermore, it seems like it's only shooting in Automatic mode, regardless of which mode is selected. I subsequently bought an 50mm AI-S Series E, figuring that the program mode problem was due to the 35-135mm zoom included with the camera not being an AI-S lens, but while dry firing the camera before loading a roll of film it seemed to ignore my shutter speed setting in all modes but manual, just like the zoom. (I expect the roll of film to come out fiddly, as the shutter error occurred after loading and I had to resort to compose-meter-recompose until finding something at a shutter speed of 250 and then change to M250 to take the shot.) Is there something I'm unaware of that might disable the shutter release button on a Nikon FA in the way I describe? It feels like the button is depressing all the way, past where the shutter actually trips, but nothing happens unless I set it to one of the manual modes. Going by a major repair shop's prices, at $55 + shipping for a minimum repair I might eke by, but with an overhaul estimated at $190 I'd end up paying more than the cost of an 'excellent condition' body on the used market. I'm still excited about the resolution and dynamic range of film, and the camera is so compact and feels so good on a strap and in hand compared to the 50D I've been lugging around for a year that I want to make it my normal daylight camera, so I can leave the DSLR in the car unless I'm shooting at 800+ ISO. I'm just hoping I didn't blow a hundred bucks on a Catch-22.
