What is a fair price for a used camera and lenses?

A friend is offering me a Cannon A-1 35mm camera(about 20 years old)+ several lenses. These include a macro zoom lens and a wide angle lens, as well as a 28-50mm zoom lens and a few others that are just basic lenses. All together about 7 lenses. Also an auto winder attachment, a couple of cable releases, about 12 filters, several lens adapters, a light meter and a bellows. I need to figure out what to offer her, but I don't know what is a fair price. I don't want to cheat either one of us. Does anybody have any idea what would be a fair price to offer for these items. I must have the camera and at least a couple of lenses, along with the cable releases, and at least a couple of filters. So an idea of what to offer for the smaller number of items would also be helpful. Thank you.

Since Canon developed the EOS camera system, the A-1 vintage cameras became obsolete ... sort of. While they are still great cameras and can shoot amazing images. What you will not get is auto-focus and the ability to use the new Canon EOS and DSLR's cameras.

A fair price could be as low as $200 for the whole kit. You will not be cheating anyone by knowing the limitations of the camera and lenses.

I think $75 - $100 for the camera body.
$20-50 for those lenses.
$10 cable release
$5-10 for each filter.

I would look at an on line store that deals in used equipment like KEH (See link below). They have a rating system for quality and tell you what they can guarantee (if anything) for various conditions.

For example they rate an A1 with no lens in excellent condition at about $140. Keep in mind that they guarantee the camera to work and offer a 60 day warranty at that price so that should be worth more than a private transaction without any guarantee. Also they charge premium prices so you would probably be able to get it for less on eBay, etc.

They will have most of the equipment for Cannon. The filters and accessories will be harder to value but a rule of thumb would be that filters and cable releases should be about 20-30% of the cost of new ones.

Hope that helps.
