Re: Need lens pricing advice
Can't help with the spotmatic question, but I got a MG with a 50mm asahi pentax f 2.0 and a generic zoom lens for $10. The camera needed light seals, and the zoom lens wasn't very good, but the 50mm was a gem. Well worth much more. I basically got the full kit which included bag, manual a couple of filters, etc....a great deal in my opinion. Hope you get as good of a deal.
Re: Need lens pricing advice
Check out keh.com They have a comprehensive range of Lenses (for any system).
I have a spotmaitc as well, with a Super Tak 55mm and a 90-310(?)mm lens.
They are reasonably well priced, and keh have a really good reputation. Hope you find what you are looking for. :)
Re: Need lens pricing advice
I would agree KEH is a grea starting spot. The Spotmatic is worth about $30.00 and the lens not a whole lot more, maybe $50 tops. You have to consider the Spotmatic will need a CLA either as soon as you get it or within a year. Great camera but getting old and as said already, it's going to need seals sooner or later.
The Vivitar is a better than average lens but not that much better. Can't help on the other lens. A complete guess is also around $30. These old zooms are not really that great and zoom technology has come a long way since that one was built.
