I would like to order some screw-on rubber lens hoods for my three large format lenses. Currently I never use hoods, but have been told that they may make a significant difference in contrast and flare reduction. My plan is to buy one for each lens so they will always be ready to use. John Sexton, at his workshop, recommended the Hama brand. I am not interested in a bulky compendium type system.
So here is my question. How do I buy these for my lenses? How do I know it will not vignette? They seem to be offered in the 35mm camera section at B&H. My lenses are Schneider 90 SA XL, 150 APO-Symmar, 240 APO-Symmar. Any help with how to order these would be helpful.
