step up/down rings

Hello cowsters,

I have a 77mm lens on a Betacam and some 72mm filters, if I purchase a step down ring to convert will I
see some vignetting from the conversion?

Cheers
jim

Possibly on the wide side of the lens.Keep filters close to front element and you should be ok. Unfortunately, only way to know is to test it out.

Todd,

Thank you for your insight. I am looking to test but finding the step down ring in the area has been a problem.

Cheers
Jim
