True. The 50/1.4 is sharp edge to edge once you get to F2.8, which is what the 50/2.8 Macro is also. Same with 85/1.4 lenses. That is what got all three Pentax optical designs into Photodos top 10 highest MTF50 of all time list in the film days. Also the only company to have 3 in the top 10 (Nikon had none). That of course does not count the fact that they do not have digital lens coatings to eliminate reflections off the sensor like modern lenses do. In today's environment they are not perfect. Now on that same though there are lenses today like the Sigma 50/1.4 Art and the Zeiss Otus 55/1.4 that blow the old 50's away, no matter who made them.
