A family of endoscopes includes a non-zero degree endoscope and a zero degree endoscope. The zero degree endoscope includes a first image capture unit mounted in a distal portion of the zero degree endoscope with a lengthwise axis of the first image capture unit substantially parallel to a lengthwise axis of that distal portion. The non-zero degree endoscope includes a second image capture unit mounted in a distal portion of the non-zero degree endoscope with a lengthwise axis of the second image capture unit intersecting a lengthwise axis of that distal portion at a non-zero angle. The first and second image capture units have substantially identical non-folded optical paths.
