    Hi guys, I need a little bit of input here.

    What I'd like to know is, is this lens useful, common, rare, worth anything, nothing?

    I've never come across its type before but that probably says more about my lack of knowledge than anything else! :wink:

    This is a side view of the adapter:

    Made by Tokina and much admired in it's day. Don't know how it would fare against modern glassware but if my days with the old Pentax MX remind me properly I would think it be pretty good with an adaptor. Hope this helps a little.

    With the glass element in the adapter I'm guessing it's some sort of tele-converter...

    It certainly looks like a tele-converter. The EC20/EC14 are similar (without the tripod mount).

    What you have there is a Vivitar 90mm Macro with an adapter that makes the macro 1:1. By the serial number you can tell it was make by Tokina and it looks to be a M42 screw mount. I wouldn't say it is really rare or valuable and it does not seem to be all that great of condition. Cruise on over to eBay to get an idea of what they are worth. With a cheap adapter I'm sure you could get some fine portraits or macro shots with it.

    Yes made by Tokina as indicated by the first two digits of the serial number - 37. That is not a telextender but a 1:1 adapter. This lens is also known the "Bokina" for it's extremely soft bokeh. here is a thread with photos -

    Now that's a power of information!

    I'm going to screw my G2 onto the end of it and mount the whole shooting match on my 141RC head. I'll require a dedicated team of Sherpas but having checked out the links provided by you good people it looks like it might be more than worth the hernia.

    Thanks! :2thumbs:

    Just wanted to add re: condition - if you look at the 'head on' photograph you can see a bluish tinge at places between the outer housing and the lens barrel. This is because the original blue plastic film is still firmly attached to and completely protects the extending barrel of the lens. I should have photographed it but hindsight, eh?
