Hello There....This lens is in very good condition with SLIGHT signs of wear and  a little ripple on the filter thread area (just visible near the serial no..) which does not affect performance or mounting filters.

There is VERY little paint loss (the photos show reflections that make some areas look like bare aluminium....Doh!) SO......

If you are not completely happy with my description....I will have it back AND PAY YOUR POSTAGE.

It's a bit of an unusual animal as the lens splits in two!

When it's all together , it is a 225mm f7.7 (!!) tele photo

and if you take the mount off , remove the back half and put the mount back on the front part , it becomes a 135mm f4.5.

It's MEANT TO DO THAT  ......HONEST!

There are TWO sets of apertures on the pre-set function ,one white ,the other GREEN...(because all the markings on the "converter" are GREEN)

It's quite small and compact....only 105mm tall !

I know it's not worth a great deal but wouldn't it be fun to put it on, say, a digital Nikon...eh!     (Either with a T mount or the M42 to Nikon adapters readily available on the net)

PS Sorry, no caps.....

Thankyou for looking
