    I prefer the wire as it allows one to see the action as it enters the frame, thus the old name of 'Sports Finder'!

    It's also not expensive fragile glass.

    Yes, and another clever thing was the Hasselblad sports finder that projected the focus spot as we looked through the wire frame finder. Another was an air-to-air 4x5 with FP shutter that used periscope focusing. Can provide details if needed.

    My pleasure! Here is a page that shows the Hasselblad finder. Note how the eyepiece is directed onto the focusing screen, and one can still see the sport view frames. http://www.clubhasselblad.com/hassel...rts-viewfinder

    The air-to-air 4x5 was a Peckham Wray. http://www.digoliardi.net/peckham-wray-1.jpg Focusing was through the little prism-sight on the top which only showed a bit of the center of the image. Framing was by the obvious frame just to the right. When you pressed the expose button the little internal mirror flipped up and the focal plane shutter fired. Not split-second stuff.

    I can supply more pictures of the Peckham, but seriously it has been jailed in its original leather case to the outdoor porch to air out since I got it long ago because it is toxic! No kidding. When I got I noticed its unfamiliar smell which I could also taste. I left it by my bed when I went to sleep and I was so sick the next day. It might be coincidence, but considering it came from a diabolical British military base that killed recruits in its experiments, I don't trust it one bit.

    When our weather improves, I can take it outside in the breeze, take it apart and make good photos.

    Thanks for your interest, Randy Moe.

    No discussion of sportsfinders is complete without mention of the Rolleimeter; Rangefinder adapter...

    ...and the built-in sportsfinder with the peekhole in which you could view the ground glass to focus (similar to the Hassleblad mentioned above).
    However, due to two mirrors in the light path, the image, is not only reversed left-to-right, it is upside down also (the normal view on this forum).

    All very interesting. I got a couple Linhof wire finders. One has 3 folding objectives. The other 2. They fit anything with a cold shoe and were cheap as nails. I did buy them. I use them on a variety of formats and lenses. They even adjust for parallax distance.

    Yep, i have them as well. I like the red glass bead dot. Good old ignored technology - that works!

    So the horseman zoom finder is easy to disassemble. I adjusted the gearing so that 210 on the dial corresponds to a 210mm lens. Now it's correct at that point , but still inaccurate throughout most of it's range. It's Easy to reset to factory build if needed. I hope the engineer that designed this finder lost his job.


    Can anyone confirm that the newer linhof zoom finder is more accurate through it's range?

    I've used the new Linhof finder a lot on my Linhof as well as on other cameras and it's really accurate. Surprisingly accurate - I usually frame a bit loose expecting inaccuracy but generally it's dead-on, unless I forget to properly set the parallax correction distance.

    My finder shows blurred edges of the 6x9 mask while seeing thru. Can anyone confirm?
