My top rangefinder has interchangeable cams, it's great if you can find a cam that matches your lens it's not focal length only.
    Side mounted Kalart rangefinders are easy to adjust for use with different focal lengths. It does require removal of the cover,and a stationery platform and focalpoint, so it is not a field alteration.

    Interesting. How would that be done? Would you scavenge a Kalart from a Speed Graphic? Can a Kalart rangefinder be taken off a Graflex 2x3 and installed on the Crown?

I only had time to check it at near distances, (~60 inches) but the thing is dead-on accurate wide open. I couldn't focus any more precisely using my 8x loupe on the ground-glass. Pleased as punch! Now I await my tri-x and Ebay-film holders...
    I've got a top and side rangefinder Crown with same lens 135mm Xenar. The rangefinders are deadly accurate.

    There are many versions of the Kalart range finder. I don't believe that the Kalarts used on 2x3 Graphics can be used on 4x5ers.

    You should be able to scavenge a Kalart from a Pacemaker Graphic, not from an earlier Speed Graphic.

    If you find a Kalart, you'll need mounting instructions. I b'lieve they came with a template for drilling the mounting holes.

    New old stock Kalarts are basically unobtanium. Since you have a top RF Crown, you'd probably be better off learning to make and change cams.

    Now I know how very lucky I was to find a Super Technika 4x5 V with three lenses with cams matching the camera serial number and each lens serial number. I feel blessed. (There has been some speculation that the V offered no-such. I don't know, but transition models do happen.)

    Re: School me on press cameras.

    I installed a tiny laser inside the FocuSpot and use it only on inanimate objects.

    It makes focusing at night easy. Also works in daylight.

    I posted it some years ago in DIY.

    The usual warnings apply.

    Don't use on any creature with working eyes.


    I am working on enlarger and studio camera auto focus as my eyes are crap.

    New IR distance sensors are cheap. A feedback loop may help me.

    The question now, is 850 to 950 nm IR safe for eyes.

    Read that and think about it.

    No transition models. It is a IV or a V. However, both models were available at the same time for a while so your cams and camera were probably crammed at that time. That would probably mean that it occurred around late 63.

    Thank you, Bob.
