[Leica] More RD-1 Samples

[jls at runbox.com (Jeffery Smith)]

But if your lens resolution is (for example) 100 lines/mm and you are
using only a small part of the 35mm frame, that 100 lines/mm becomes
much more important because you have to expand that space. The advantage
that we see using medium format over 35mm is similar to the advantage we
see using 35mm over an APS sized sensor.

I think you have the gist of it.

The smaller sensor size just crops the image to the middle of the
traditional 35mm frame so you can take a scan you've made of a full
frame 35mm image and manually crop it to see what the result of using
that lens.

And  yes, especially for the M lenses, it's getting the light down
into the pits of the sensor that appears to be the major problem.
