Kori Perez Posted September 17, 2008 Share Posted September 17, 2008 (edited) I have a Bolex SBM that will soon be modified to super 16. I wanted a nice wide angle that covered S16 and I picked up a c-mount Kinoptik 5.7mm 1.8. It is a fixed focus lens that seems to be a bit out of focus thru the viewfinder. I think it needs to be collimated (?). Images only come into focus when I use the lens like a macro up close and personal. I'm sure this problem is due to my reflex prism. How would one go about fixing this problem? Thanks! Edited September 17, 2008 by Kori Perez Link to comment Share on other sites More sharing options...
Mitch Gross Posted September 17, 2008 Share Posted September 17, 2008 Send it to a camera rental house that can mount a c-mount lens on a collimator bench. Link to comment Share on other sites More sharing options...

Premium Member Ken Hale Posted September 20, 2008 Premium Member Share Posted September 20, 2008 Will a collimator bench be able to fix the issue? I think that the best way to set this lens is by using a lens test projector. Optimize your focus for 5-6 feet, and everything from 18 inches to infinity should fall into focus due to the hyperfocal distance of this lens. I recommend sending your lens to someone that specializes in Cine lens repair. Link to comment Share on other sites More sharing options...
