Yet you still don\'t get it. IT DOESN\'T HAVE AN IR CUT FILTER!
Do you know the difference between IR absorbing glass and an IR filter? If not, please stop trying to argue with someone who understands the principles at work in the camera being discussed.
The reason for the M8 having the IR issues is because they chose to have a THINNER IR-ABSORBING coverglass in order to maximise sharpness with extremely oblique incident rays that occur in rangefinders, I can explain that in optical theory to you as well if need be. Do I need to tell you how IR absorbing glass works as well? Joe is merely incorrect in this case, obviously he hasn\'t done enough research into the camera itself. I trust Leica engineers for an explanation more than I trust some guy on a forum.
How they overcame it in the M9 is through using a better glass type for the absorbing filter allowing them to increase the thickness by 0.3mm and giving an effective enough IR filtration without lowering sharpness. The cyan drift is more severe because of the more effective filter, why we haven\'t seen any examples (this point is for kidtexas) is because people can select profiles for their uncoded lenses in the menu. I\'ll happily show you some examples in about a week.
