As I was trying to check the focusing of my Super Ikonta 531/2 with a Tessar 105 mm f/4.5 I observed that it shows front focusing at full aperture - for a focus at 1.50 m I had to turn the scale to 1.65 m while it look as if it is spot on at f/8 and 1.50 m.
Is this ammount of focus shift normal for front element focusing tessar type and triplet lenses?
