Here is a set of close up macro bellows which have been sat in the cupboard for a couple of years, since I last played around with extreme close up. Pl see photos for details.
They in good (little used) condition. All thumb screws are in good order as are the bellows, they are solidly engineered.
There are adapters included for Canon Fd, but these are interchangeable and I've seen others on eBay.
I'll answer any questions to the best of my ability.
