Last spherical M-50/2

Leica M Summicron 50mm f2 standard lens shown in the picture is the last spherical model after several improvements and generation changes these 60 years. I recommend this one as the ideal figure of ultimate of optical construction, aberration corrections, color balance, resolution, contrast and another requirement as a standard lens if used even on digital formatting images. Though there has been announced a expensive new apochromat model now, no more performance than this last spherical 50 mm M Summicron is desired for my personal use on earth. If I was forced to obtain only one photographic equipment to be allowed, I will choose this lens and M9 digital body without any hesitation.
