Hey everyone,
So this question came up at work today and so I started to investigate it. Background on the question, I work for the Savannah College of Art and Design within their Equipment Cage and currently act as the "semi" camera tech till they officially hire me for the position. Anyway a student ran double perf 16mm in one of our SR2's and some of the other staffers referred this to me because they were unsure if any damage could have occured.
I looked and it looked fine but I was curious anyway because this problem has occured before. Now I have never heard anything wrong with running double in a single system, just the other way around, running single perf in a double perf system is bad (obviously because of punched holes and such).
Anyone else have any knowledge on this subject or is it something that the students shouldnt worry a ton about?

I don't see how this would cause any damage. Should be fine.

Does not cause any problems or defects whatsoever to the camera mechanics. No need to worry!

Nothing to worry about. Was it a regular 16 SR2 or a Super 16 SR2? If it was a Super 16 SR2 I'd love to see that negative. :rolleyes:

I have shot a ton of double perf in my Super-16 aaton ltr never had a problem, the image extends all the way to the right side, minus two sorta square chunks :lol: certainly does not affect registration or steadiness.

Until they started pushing super 16mm double perf was what was shipped as default unless you asked for single. The Camera just does not see the perfs as it is not looing for them. If you are shotting for Super 16 frame you would get these two looming rectangles on teh right of the picture however.

Would also give funky results if you were trying to use single system sound in a auricon. BUZZZZZ.
