On advice from the LUG, I found that the front threads of my Jupiter 9 are 49mm. I looked yesterday at all of my local shops in the used bin and new racks for a lens hood and all of them are flared to too wide a diameter and block half of the 90 frame in my Bessa's VF. I really don't want to use an aux finder for a lens with a built in frame in camera so have decided to make my own hood with a 49mm UV filter (glass removed) and some non tapered dark metallic 50mm (or so) tubular material. My question is does anyone know from experience or formula, how far the hood should extend from the front element to provide maximum shade, without intruding on the image and darkening my corners?
