Has anyone ever made an aperture? I have a CZJ T50/2.8 with sticky blades and while I was taking it apart, wondered how hard it would be to design and fabricate a new one (taking it to 9, 11, or more blades). Has anyone ever heard of or tried anything like that? |

Never heard about a DIY build iris. Repair of an iris is common, but to make the very thin blades and their cones would be much work. _________________ Camera modification, repair and DIY - some links to look through: http://www.4photos.de/camera-diy/index-en.html

Making one from scratch sounds daunting, you might be able to salvage one from a donor lens.
There's an ebay seller with a prebuilt aperture thingy, looks like it's intended for people building or converting lenses.
