I must admit I can't see that the sharpness of my 165mm Angulon is limiting in any way - I would be happy with that resolution on film in a 165mm lens for 35mm! I think some early super-angulons may well be less sharp than plain angulons of the same age?

The real difference will be comparing a wide-angle Aplanat with an early Angulon. I'll try that next month.
