Be deliberate! Be strategic! Knowing the boundaries of your scene is vital to compositional and artistic control. These viewfinders straddle the body clip and give an accurate angular guide to composition. Keep in mind, for very close subjects, parallax effects will become significant.

These can be used as is, but they are designed to temporarily snap together, mated with either a short length of 3mm filament, or 3mm rare Earth magnets, which will hold the VF in place - even inverted.

These should be robust parts, print with 0.25mm layer height for accuracy and 2 perimeters/50% infill for strength.

A 6mm length of 3.00 mm filament can be used to peg these parts together (glue only in the top of the body clip) or 3mm rare Earth magnets can be employed to hold them together.

The holes are a nominal 3mm, but may need some enlarging with an appropriately-sized drill bit. The 3mm magnets I used are precisely 3mm; an 1/8 inch drill bit is approx 3.15mm. I used the next smaller size, 7/64ths and slightly enlarged the holes. If you're using superglue, you have essentially one shot to get the magnet seated completely in the hole.

That's a very good addition to the pinhole P66 :)
May I ask you how you have designed its dimensions ?
My baby bessa doesn't have a view finder ....and I was tempted to builld one !

If you know your "focal length" and frame length and width, then you have the dimensions of a pyramid that corresponds to the cone of light that exposes your film. Flipping the pyramid 180 degrees, gives you the vertical and horizontal angles of view into the camera. I shrink or enlarge [edit: SCALE] the pyramid as needed and that gives me the inside dimensions and angles of the view finder. For very close work, there will obviously be some parallax.
My terraPin designs have no viewfinders, but I want to make a WYSIWYG finder that swaps out of the tripod mount. Stay tuned.

Thank you so much :)
I managed to work with it (sort of).
I'll post it in a few. Just one more question ...how do you decide to cut the depth of the viewfinder ?
I did it abritrary at a given length.
It is roughtly 30mmx30mmx20mm :

  • 6x6 film at 50%
  • the pyramid is cut at 2cm ...to have something I can view trought

I want the angled sides to be long enough to use as accurate sight lines, but the depth is totally arbitrary.
