2 of the new Leica +1 Macrolux diopters just made it to our shop. They will clamp on to our Leica Summicron primes, bringing close Focus with edge to edge sharpness to some of the best lenses available. Being stackable and having a 95mm clamp, these will also work with our Zeiss 70-200mm Compact Zoom or re-housed GL Optics lenses. 100mm Macro being one of those options……. HOW CLOSE IS TOO CLOSE?!?!?!
