Description
This is a Viewfinder for the WillTravel camera series (see my other things)
Design based on the el chepo smartphone macro lens ($6-$9) that I was tipped about earlier this year. Provide a approximate correct field of view for 90mm @4x5 in the shown configuration, remove the rear eyesight and your eye gets closer and you have approximately field of view for 75mm @4x5.
Masks for 120, 135 and 150 are work in progress, same for a 5x7 ratio opening.
Laser rangefinder is a small Golf LRF type up to 30+meters, handy for seting up zone focus scales.
