Curious if anyone has any experience opening this lens to get to the aperture-I need to clean the blades-they're very slow to react.





Cheers

I don't have experience with this lens, most likely it's similiar to other Schneider Kreuznach lenses. Which means: unscrew name plate and front element to reach aperture blades from the front. To reach them from the rear, remove the mount which is usually fastened with 3-4 screws (optionally there is a cover which has to be unscrewed first to reach the screws). Look out for grub screws which might secure the mount/cover additionally.
