The way I understand it is that 'full-frame' is a fisheye which throws such
a large image circle that it fills the 35mm frame rather than producing the
'peephole' effect - you get a rectangular section of the centre of the
fisheye image. 'Rectilinear' means that some attempt has been made to
correct the distortion so that you get a more 'natural' looking image.
"Rectilinear" suggests, as a word, that the lines in the image conform to a
rectangle - aren't bent too much at the edges of the pic. The Voigtlander
12mm is corrected but I would find the width pretty terrifying, especially
on a rangefinder.
