Hi, thank you for contacting JustAnswer.com. My name is***** will do my best to provide the right answer to your question.
The Canon Ae-1 35 mm camera (if that is the model of 'A' camera you have) is offered for about $100 to $200 or so, nowadays. Sometimes for $300-odd, if it is complete and with all accessories... but that price might be a bit bold and less likely to sell.
The Tamron CT Telephoto Macro 1:38 I cannot quote a price for, that could be several different lenses. If that were a CF lens, then it might be worth $20 to $60 or $80 at most, unless in very good condition and with all extras.
The other Tamron lens, the Matrix, sounds like info gotten off a UV filter mounted on the lens, not off the lens itself. For info on that lens, please state only info on the lens body itself, and all the info, and I may be able to figure out its worth.
The Vivitar Zoom Thyristor 285, is worth about $20 to about $60 at most. But it will sell at prices in the lower part of that range.
The camera is, in short, much the most valuable of that set of items.
