I'm not seeing any advantage of the Leica using an additional, and very expensive, optical accessory to gain 1:1 (and losing infinity) as against adding glassless extension tubes to the Zeiss MP to gain 1:1 (and lose infinity). Or am I missing something except saving hundreds of dollars ?
As for the Zeiss MP100 I can't tell. Extension tubes may work well here.
As for the Leica AME100, I was told by an engineer from Leica in Solms/Germany, that they don't recommend using this lens with extensions. According to them, the AME100 is, because of its very optical design, relatively (acc. to Leica standards...) prone to optical aberrations as soon as any extension is applied. I never tried that (had the Elpro). He also admitted that this may hardly be visible in real life.
In principle, extensions always degrade IQ of "non-dedicatedly extendable lenses" of any kind (also many macro lenses) as the optically optimal flange distance of such lenses is rather narrow. Yet, different lenses behave very differently here. Often enough only the corners are affected while the center (and the field) remains very good. Depending on DOF (usually quite small anyway with macro work) and composition, and the lens of course, this might not be an issue at all.
Cheers
