I tend to feel that a 1960's lens should be better than a 1940's lens.  I
didn't notice a specific sharpness difference in my test rolls, however.
Just contrast and saturation.

I guess that the ISO Super Duplex 120 isn't a very well known camera.
While it uses 120 film, it shoots 24 pairs of Realist size images side by
side, with a lens base of 30mm.

                        |[][]|
                        |[][]|
                        |[][]|
                        |[][]|
                        |[][]|
                        |[][]|
                        |[][]|
                        |[][]|

Thus the images from the Duplex and the Realist have the same grain size.

Also, one of my main interests in raising this issue is to find out whether
something more recently built than a Realist, say a Belplaca (1955), would
likely have lenses capable of that 'snap' I'm used to in my Duplex.  The
Realist, while sharply in focus, did not.

I really like my Duplex, but for long shots and landscapes, a 70mm base
would be more effective.
