Leica has said that they prefer to engineer the lenses as well as possible rather than correct errors later. Naturally that is simplistic and there are interdependent priorities and philosophies there. In principle I think that many Leica enthusiasts prefer the second approach. One recent development that I found interesting is the release of the new DNG 1.3.0.0 standard. As I understand it, some firmware operations, such as lens corrections will be moved to the converter. This potentially has significance for Leica firmware and future products. Well worth pursuing on the Adobe sites if you are interested. http://www.adobe.com/products/dng/pdfs/dng_spec_1_3_0_0.pdf 2009/7/22 Richard Taylor <r.s.taylor at comcast.net> > Mark - I think this design approach is going to lead to a whole new > generation of light, small and highly capable lenses.
