    Just finished this little project, using repurposed 35mm viewfinder parts with framelines from a Canon Sure Shot Owl. The housing is 3D printed.

    Good match for the 23mm Fujinons.

    The Owl has perhaps the largest viewfinder in a P&S, with 0.68x magnification, and close up marks. These cameras can be acquired for a song on ebay. (I paid $7.33 for one, and $10 for a second, including shipping.)

    Total weight when assembled 14g, or 0.5oz.

    A great big view with zero weight!

    Did you glue the hot shoe adapter underneath? Brilliant idea.

    The viewfinder optics are removed and placed into a 3D printed housing with the accessory foot.

    Obviously, otherwise I would not have responded.

    Are you using Tapatalk? That often has a problem with showing images.

    Yay! Is the optical pack in the Owl behind plastic? I’m curious how clean of a donor camera is needed. If the optics are encased behind windows that opens up the prospects considerably.

    The two donor cameras I bought were not very very clean, but the optics were easy to clean up with a microfiber cloth. There are three optical pieces, the two outer ones are open to the elements.

    Here is the list of camera models that have these viewfinders. Each line lists an identical model; the alternate names were sold in different markets.

    • sure shot owl - prima af-7
    • sure shot owl pf - prima af-9/date
    • sure shot owl/date - prima af-8/date
    • snappy lx - bf35 - prima bf
    • snappy lxII/date - prima bf-8/date - BF35D
    • snappy lx/date - prima bf-7/date - BF35 QDN

    I bought a Sure Shot Owl, and a Snappy LX. The Snappy LX did not have the close-up marks on the framelines.

    Bear in mind for close-up shooting (anything closer than about 3 feet) with a Fuji, use the EVF or LCD.

    For most applications including street shooting the close-up marks aren't really needed.

    My donor Sure Shot Owl should be delivered in a day or two. Have you had any luck uploading the project?

    Ok, the housing is here and looks great. Robert, can you provide guidance on how to best extract the finder from the donor camera? Also, does the housing need any treatment before use (i.e. Bestine?)

    Hi Ken, no special treatment, just a couple of drops of glue (superglue) to secure the top, placed into the two holes. Make sure it doesn't get on the optics!

    As far as taking the camera apart, since there are so many variations of the Sure Shot Owl/Snappy, this attached pdf might vary somewhat from your camera. This was something I found on the net, you don't need to remove the battery door or the shutter button.

    But basically, remove all the screws you can find, and then split the front part off from the rest of the camera. It should pry apart fairly easily with a screwdriver.

    This should expose the the black plastic piece that covers the viewfinder parts. Remove that black piece and then pull the three optics out and place them in the same relative locations in the housing.
