This is a Tamron Adaptall CF Macro 35-70mm f/3.5 manual focus zoom lens with interchangeable mount - the pictures show it with an Olympus OM mount, alternatively I can supply it with one of the following mounts: Konica (unable to test), Minolta MD, Fujica F/AX (no rear cap). I'm supplying it with its original caps and a cloth storage bag. This is a manual focusing lens; stopdown is automatic via a rear linkage, with open aperture metering supported if the mount and camera allow it. It has close focusing (0.85ft) at 70mm

This is very slight internal dust which does not appear to be affecting results, condition is otherwise very good. There does not appear to be any fungus or spores.

I tested operation on an Olympus OM10 body and stopdown, metering etc. worked well. Test pictures were taken with a Canon Eos 40D body with Olympus adapter. The lens was set to f8 for all pictures. Weather was slightly cloudy with variable lighting.

Coin and brick bits on roof (7ft) 1/1000th and 1/1250th f8

As usual I'm starting low and with no reserve. I'm separately selling some other photographic items. If you buy multiple items from me please request a combined postage invoice, I'll do my best to get it down to the lowest possible price. I do not make any profit on postage.

International buyers: The postage price shown is based on an estimate of packed weight, just under 500g. This will be sent by a tracked postal service; if multiple items are sent (max 2kg total packed weight) the tracking applies to the whole package and works out cheaper per item. Please note that eBay will add VAT or sales tax to the final price including postage in the EU and some other countries.
