During my testing of the new Leica M Monochrom (Typ 246) in NYC and New Orleans, I was blown away by the camera’s high ISO ability, so I wanted to see how it stacked up against the original M Monochrom based off of the M9, as well as the Leica M (Typ 240) when converted to B&W.
These kinds of tests are never easy or clear-cut and there were some obvious challenges. I’ll address these and how I decided to handle them.
M Monochrom (Typ 246) vs. M Monochrom (M9)
There is a resolution difference between the earlier M9-based M Monochrom, which I’ll refer to as the M9M, at 18MP, and the new M Monochrom (Typ 246), which I’ll call the MM246, at 24MP. Others might have uprezzed the M9M up to match the MM246, but I feel this can actually have a detrimental effect on image quality as we’d be doing some non-integer scaling. Such scaling can create a loss of per-pixel acuity. Also, if you have read my thoughts on uprezzing before, you might recall that I’m not a huge fan, even when printing big. My preference is almost always to output files at native size and let the printer driver handle the scaling. So, I decided to leave each one in its native size. You’ll see the resolution difference in the comparisons. Please keep it in mind when making your own evaluations.
