Hi, I've made a few finders for my Leica 28mm and 35mm from old disposable camera viewfinders. But I have 24mm, 20mm and 17mm lenses I'd like to use. Using them is no problem and focus is hardly an issue. But when I use them its pure guesswork what's in the frame.
I've looked online for finders, the 20mm Russar finder is about £150 and anything else is well into the £300 plus bracket.
Does anyone here have plans or can they show me how to make ultrawide finders?. I'm pretty handy and once I know what I need I'm sure I'll be able to do it. No 3d printing if possible. _________________ Hero in the 'messin-with-cameras-for-the-hell-of-it department'. Official. |

The obvious technique using readily available tools always with you... http://www.hollywoodlexicon.com/frame.html
Then there's the calibrated Director's Viewfinder, check ebay
A diy director's viewfinder can be made with one of those adapters that turn a lens into a monocular, plus a cheap zoom lens. _________________ ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮ like attracts like! ☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮☮
