This is for all you canon users (anyone else is welcome, of course!). I have just bought myself an old Canon A-1, something that wished to do long ago. I must start saying that it was at eBay, so... who knows what you're really buying? I must also say that I previously had very positive experiences there, so I was not afraid trying. But now I'm beginning to be... At first the camera seemed really good. All the main functions seemed to work properly. I checked the metering with my reliable Nikon and it worked fine; so did the shutter (or at least that's what it seems: I still have to shoot film to be sure!). But after further inspection, I've come to a couple of issues -or that's what I suspect them to be: The first one seems to be clear; or very little doubt: the DOF button doesn't work! It should close down the diafragm when directly selecting the apertures, instead of "A", right? Well, it doesn't. Strange for me is that you can do your own DOF preview by using the stop-down lever, which does work. So this wouldn't be a major issue (although rather bitter, since it was not stated by the seller!). To the point. The first thing I want to ask you is for trying to find out where the problem lies: Shouldn't I be able to close the diafragm manually when having the lens out of the body (as with other lenses I have)? I mean, by moving the switch that attaches to the camera functions. If the answer is yes, then the problem could be on the lens, because I can't with this one. And yet, the stop-down lever works... any idea?? Now with the second issue. This worries me much more. I am afraid (please not!) that the back cover of the camera might not shut properly, so light could leak. It seems that this camera is built like a tank, not plastic at all, so in that sense it should be reliable not to develop this kind of problem. But still, I see something I don't like. Sorry, I know it sounds stupid, but here's the question: does the back cover leave something like a milimeter distance to the body in the side-end when it closes? I don't know if you get what I'm trying to explain (I could later post a picture; I've been trying to compare with other pictures of A1 on the net, but none shows clearly this part). For me this is new: the other cameras I have don't leave this "space", and the back doors lean completely against the body, even in the side-end. This one seems to do it ok in the back (although if you push, you can still feel it moves a little), but not in the side. Is this normal? And that's it... I believe. I hope I won't find any more issues. I have just put a film and will shoot it as soon as possible. That's the best way to know what have I bought! But until that happens, what do you think? did I buy a lemon? 'cause if I really bought a decent a1, then it was a real bargain (a real one!), but for a lemon... that's a lot of money!
