^Nice, Alex. Is that from the one you just sold or did you keep a copy as well?
Today I am a happy, happy shooter. I bought a Minolta APO 1.4x to see if I could get it to work with Leica lenses. Initially, I ran into a couple of problems that I thought might require surgery on the lenses themselves. The aperture arm was getting hung up when mounted, so the lenses wouldn't stop down. But the quality shooting wide open with the 100/2.8 and 250/4 was good enough to make me pull apart the extender to see if I could get rid of the interfering parts. First and easiest to go was the rubber guard around the front element, which just left the converter's aperture control lever, which came off with a couple of screws. Since I had it apart anyway, I also removed the electronic components, so I don't have to tape over the rear chip to use the converter. Everything is 100% reversible if I ever decide to switch over to Minolta AF lenses, though the odds of that happening are very low.
Not only does it work, I can't tell a difference between it and the Leica 1.4x APO (except that, cosmetically, the Minolta is white). I'll shoot and post some test shots with the 180/2.8 and 250/4 using both converters when I get a chance, but I think this is going to work out very well indeed. The Minolta, thanks to its design, has the added advantage of working with lenses the Leica doesn't, like the 100/2.8 and 180/3.4, so, bonus!
