I recently acquired a 21/4P which comes with the box but unfortunately not the manual.
I have always been curious on how the 21/4 and 28/3.5, both lenses I now own and enjoy, measured up in Cosina's official literature (which unlike the ZM lenses, lacks an online presence). I wonder if Cosina included MTF and other charts in the manuals the lenses came with? If so, would someone be nice to post some scan/photos of those manuals?
Thanks a lot!

I have never seen any MTF data on any CV lenses. I have several LTM CV lenses, 25, 28, and 35 and have no manuals for them either. I assume they may just come with a little pamphlet or something. They do get the job done, even if they don't come with data. Mine are sharp and contrasty.

Mine came with a minimal instruction manual, just some specs and a drawing of the lens with the nomenclature of the various lens parts like aperture ring, distance scale etc. No MTF charts.

Thanks guys, that's about as much information as I could hope to get on the charts. Still do love my 28/3.5 (so much that I had to buy it twice), which produced some favorite images.
