I read not good reports on Canada Mandler ELCAN designed Crons. They have least half the resolution of a Leitz Wetzlar older generation lenses and tend to lower the resolution at left and right. Its a worldwide discussion why is that. I used 50mm cron on Leicaflex and too hot colors at sunlight for my taste. And there was too much contrast at highlights. BUT BUT If you go to dim light , shadowy area , for example if you dont live at Florida but North , there is excellent , very very classy colors palette and degrades. Skin tones are excellent , I did not see an equivalent colors at any other 6 of my Leitz Wetzlar lens. In my opinion , Leitz lenses have a reputation because whereever whatever you go and do , they Works matchlessly. Newer Leica lenses have not this quality.
