    But you want the eyes in focus, don't you?

    This is an old thread I dug up to avoid opening new ones. After reading all the posts in it, and now some time has passed, does anyone know of a feasible direct replacement for the bulb in the top-mounted Graphic finders and the Kalart Focuspots? My complaint is that in many instances the normal bulb filament is just too dim. Given a nice bright beam on subjects can translate to a true point-and-shoot camera without having to do anything more than holding the camera up and giving nothing more than a cursory glance through the pull-up sportfinder, and click.

    Take an old bulb, remove the glass from the base, and solder/epoxy a high-intensity LED to the base.

    Superbright LED's has LED equivalents for most flashlight-type bulbs, no particular need to drag out a soldering iron. Though you could probably end up with something brighter if you use the DIY approach.

    I don't recall what bulb the FocuSpot takes, but I'm pretty sure it's a screw base. Flashlights haven't used these in decades, although the bulbs are still available.

    This can be done, and I have done it.
    To begin find the low cost "laser pointer" found mine at the dollar type store. This has three button type batteries. Take the bulb assembly out of the focus spot. And now go to the hobby store and fine the brass tube that slips one size inside another (K&N is the brand I use) and find the size that fits inside the focus spot, and the necessary smaller sizes to fit over the purchased pointer. What you are doing is making the sleeve or sleeves to keep the rangefinder centered in the focus spot housing. In my case I made the outboard battery housing and switch assembly and wire leads that go to the range finder. With the left hand I can turn the light off and on while holding the camera and focus with my right hands. This has worked for me.
    Since I do not do digital will have to ask a friend to take the photos of what I have done if anyone is interested.
    Where the focus spot attaches to the rangefinder there may be the small lens, depending on pointer and such you may want to remove this lens. A very simple way to do this is remove the focus spot and just aim laser from the top of the rangefinder.
    A reminder do not look into rangefinder while doing this. You will have the two laser spots going forward and one laser spot going to the rear from the eye piece. Do not look at laser!

    Good luck

    I think an LED arrangement would be smarter all the way around.

    Yeah, save that pocket laser for aligning rangefinders on old Leicas, the idea of staring into a laser doesn't appeal to me. The bright LEDs are obnoxious enough, but at least they won't fry spots on your retinae.

    You could use the above mentioned brass tubing to make a small piece that screws onto the RF, containing a couple button cells and having a pushbutton on the end. Press the button, focus, click. Maybe I'll make one for my Linhof... and I have an old box of Royal-X in the freezer!

    I tried a 4.5 V superbright led flashlight lamp in the Graflex rangefinder on top of the Speed.
    It did not work at all.
    It was brighter than the original filament lamp but the beams were just fuzzy blobs.
    I think the led has a lens/diffuser which upsets the original ability of the rangefinder optics to focus sharply on the filament wires
