0 in stock specialorder
The central obstruction is about 50%, but still smaller than similar designs, that simply can't compete under any point of view. The visual contrast is very good, thanks also to the special ultra-dark paints we use.
The corrector group is very close to the focal plane, so chromatic aberration is undetectable.
