Second hand Astron B30 +2 Close-up lens for sale. Used Two piece close up lens set designed for close up photography at distances closer than 1 meter. The set includes two glass optical lenses (one for the taking lens and one for the viewing lens) The larger one that goes over the viewing lens has a built-in prism for parallax correction so the view in the ground glass coincides with the photograph even at short range. The lenses fit Rollei Bayonet
good The photograph above is the actual Astron B30 +2 I am selling.
