Watameter !
- Thread starter Oldbones
- Start date
- Mount the Watameter in the camera’s accessory shoe (if your camera has one).
- Look through the Watameter eyepiece.
You’ll see a double image or split image of your subject. - Turn the focusing wheel on the Watameter until the two images line up into one clear image.
- Read the distance scale shown on the Watameter.
It might read in feet or metres. - Set the same distance on your camera lens focus scale.
- Take the photo.
You could sell that to the science museum, it will be ancient. I have never heard them even being mentioned at least since the turn of this century. So long as it is accurate it is well worth hanging on to. Anything old and as well made as these were can be relied upon, probably more so than AF in cameras.
I know it is old, and it suits the Kershaw camera I put it on, I have not taken any photographs with the aid of the Watameter so far.
I have done some calculations in the house, the wife was very helpful, so a coffee mug on a table measured at 3.5 feet, so with the tape measure the watameter was 2 inches off, and a few other similar test showed the same thing.
I am going to be busy this weekend but soon as that is done I will do some field testing.
Thing is its a fascinating wee piece of equipment looks great and does work.

2" in 42" is better than 5%. That sounds good to me. You would struggle to achieve a precision of 2" or better when adjusting the focussing scale of a lens.
Check that it works at the infinity end of the scale as well. Point it at a distant object (more than 100 yards away). Turn the rangefinder control to its infinity setting and make sure the two images superimpose properly. If that works then it's a good un.
