The sf objectives at my ipd setting are 120 mm from outside tube to outside tube and the nobilem is 198mm.So i assume its a product of the optical design ,intentional or otherwise,either way its very pronounced.I hesitate to speculate any further ,perhaps the optical design experts on the forum can enlighten us.As far as i am concerned its just the icing on the cake ,so to speak ,of a wonderful viewing experience.</p></blockquote><p></p>
