[QUOTE="jim10219, post: 2018881, member: 82696"]Because not every used camera has the same history. Some will have had routine maintenance in the not too distant past and may be good to go, as is. I’ve bought several vintage cameras that were kept in great shape and didn’t need anything other than film. I’ve bought several more that only needed light seals, which is an easy DIY job. And I’ve bought several that needed major work. I usually do my own work on cameras, because having a professional overhaul a camera can often cost more than twice what the camera will be worth after the repair. My local repair guy charges a minimum of $80 for a basic CLA. Yet he often sells cameras that people dropped off and never picked up for less than that, just trying to minimize his losses.
It depends on the camera. An old Leica will hold enough value that the work may be worth the money. An old Nikkormat, maybe not. They’re pretty common cameras and a lot of people out there use them still. I don’t think it would be too hard to find one from a photographer that’s in great shape for less than the price of finding one in poor shape, and having it resurrected to meet the condition of the former.
If the market was such that you could buy an old camera in bad condition, bring it up to snuff, and flip it for a hearty profit, you’d see a lot more people doing that. Hell, I would be doing that! But for the time being “routine maintenance” doesn’t add much value to cameras, but it sure adds a lot of costs.[/QUOTE]
That's true, but it's a matter of luck. A couple years ago, I bought a really nice looking Nikon F2A body for $100. At that price, and in that cosmetic condition, I figured it was worth me overhauling it ( I have the service manual, skills, equipment, and experience). When I got the camera (it came from an estate) I noticed it was spotlessly clean, had new foam, and the shutter speeds were spot-on as well as the meter. Come to find out Sover Wong maintains a list of cameras he's worked on and mine was Soverised in 2012. That was an anomaly (or maybe small miracle) though, I expect any camera over 10 or 15 years of age - which for me is all of them , I don't use modern electronic wonders at all except for entertainment, to need at least a cla and more likely a complete overhaul. I have an unused OM3, in the box, the foam is black goo and the shutter caps at the two highest speeds.
Maintaining an already known good camera is far better economics than buying an unknown quantity, I last serviced my Nikon F in 1998 and it's getting due for another, I've noticed it doesn't like cold weather this year.
If you're using the camera, and need it to be reliable, maintenance does indeed add to the value. I'm firmly in the "take care of it, maintain it, until it's worn out" camp, and since I'll never wear out any camera I have, I guess I need to take care of them.
