In reply to Wiley Coyote:
A professional dealer would not give you much for either camera I'm afraid. The FM2 body is worth about £30 to the end buyer. What's that - £8-10 to you from a dealer. Tokina AT-X was a respected designation like the original Vivitar Series 1, IN THE EARLY 1980s.
The Dynax 404si goes for embarrassingly little money even to the end user - tenner for the body. Shame because it's not as if they are bad cameras, and they are very light, and I know that that 28-80 is not a bad lens for what it is (I had a Dynax 5 with that lens for a bit before giving it to my Dad. I had bought the kit for £20 in a charity shop...should maybe have been £40 at the time but what that means in terms of you selling to a pro dealer is still "peanuts"
)
I did a part-ex of an original old 70s Olympus Trip in perfect nick, and an Olympus OM-20 body (intermittent unwanted mirror lock but I didn't point that out!) to London Camera exchange when buying my Sony Cybershot F717 in 2009. They gave me £5 for the Trip and £10 for the OM-20, as credit against the F717. God knows how little it would have been if I'd just tried to sell them direct.
Sorry for the bad news.
I think the Dynax 404si with the 28-80 makes a nice film SLR for climbing as it's light and compact, maybe punt it on here?
