Screw on filter size for 90mm Angulon : LUSENET : Large format photography : One Thread


I am about to order a screw on lens cover and step ring for my Angulon 90mm f/6.8. Measuring shows about 40mm. I don't want to make a mistake because the step ring is $27.43! Is 40.5 the size I need?

A 40.5 fits my lens perfectly. For $27.43 I hope you're at least buying a Heliopan ring, aluminum ones are a lot cheaper. Matter-of- fact Heliopan ones are also if you use the following vendor

He sells Schneiders at about half of the U.S. price - Heliopan rings go for about 30% of B&H's listed price.
