Looking around for a real good macro lens, and i stumble across a thread for the CZ Makro-Planer 2/100. The images look like they are 3-D. Very very sharp, and the colors look great. Ok, go to CZ site, and there they are, but, no Sony mount. Nikon, Canon, Pentax only. Is there something in the agreement with CZ and Sony saying that they will not make any manual focus lens in Sony mount?
