The patented Konica-Minolta 43mm f/1.4 lens design.
Egami spotted a patent with a surprising content! Konica Minolta patented the design of a 43mm f/1.4 Micro Four Thirds lens! The patent has been filled in 2011. Right now Konica-Minolta is not part of the (Micro-) Four Thirds group but this could change soon. Konica and Minolta have a long history of lens design for rangefinder cameras. Konica designed the Hexanon M-mount Lens series (here on eBay). That includes the superb Hexanon 50mm f/1.2 (here on eBay). Minolta made the famous Rokkor M-mount lens series (here on eBay). That includes for example the 40mm f/2.0 pancake (here on eBay).
This is just to say that Konica-Minolta would add a very high value to the whole Micro Four Thirds system! So let’s hope this is one of those few patents that will make it into…reality
