My Super Ikonta has a Tessar 105mm 3.8. I shot some Velvia slide film to test the lens and shutter. Despite huge light leaks that I have solved using the bellows patch from Bostick and Sullivan, I have not noticed a sharpness fall off when inspected with a schneider 4x loupe on a light table. Though the lens is not tack sharp, it has got plenty of saturation and I believe it will make very sharp enlargements up to 20 inches wide. I am happy with that.Originally Posted by fhovie
