Erwin Puts says:When people are talking about the Leica 19, most I guess are referring to version 2. Any big difference with version 1? I see that the price difference is quite substantial.
At f/5.6 the 20 Lp/mm are now above 80% contrast from centre to corner and the 5 Lp/mm are close to 100%. This performance is of a very high order indeed. We may appreciate the quality if we reflect on the fact that the previous 19mm at aperture 5.6 was as good as the current one at 2.8. At aperture f/8, the usual drop in contrast can be seen (see image 2 and 3).
