While I appreciate a video showing the adjustment process, rarely if ever demonstrated elsewhere, I'll raise a big caution or objection to one of the themes stated. specifically, the "expert" states that you need to re calibrate your rangefinder every time you change a lens. At face value, for these interchangeable lens bodies, that is ridiculous. Once the rangefinder is properly calibrated for any (Good) lens, it should be in calibration for all such lenses unless its parts are physically damaged. If your Canon 7 is calibrated for a good Canon lens, it will work without re calibration with other LTM lenses, unless the rangefinder cam on the lens itself is bad. A cam on a lens may be bad because the lens was poorly assembled or damaged. If you calibrate the body for the damaged lens, then all other properly made LTM lenses will not work properly. If you engaged in an idiotic process of re calibrating your rangefinder each time you changed a lens, within a short time, two events would occur: (1) you will loose one of the port cover caps, which you will never replace, and (2) since the adjustments to calibration retain their settings by friction, all of the fiddling with them will loosen them to the point where the rangefinder slips out of calibration after a short amount of knocking around. Solution: if you have a lens with a bad rangefinder cam, get rid of the lens, don't destroy your camera body.

i love your t-shirt (after 2:48) mate! :) makes perfect sense especially these days !

Please use a tripod!!!!! This will help greatly and provide a more accurate adjustment

Wow! Thank you! Thank you! For this video. This was very helpful! Thank you.

a tripod would be nice ...

You have to set a standard first or you end up in complete chaos when you have more than just a single lens a body. For instance a lens of known top-notch condition which works flawless on a camera of known condition. Take that lens and calibrate your second camera to it. If you now come across a lens which doesn't focus correctly on both cameras it is either off in flange-distance or focal length (all russian LTM-lenses). But in both cases it is the lens that has to be calibrated either by shimming the lens to its helical or inside the optics between frontgroup and backgroup of the lens. Canon and Leica cameras and bodies should be 100% interchangeable with the same calibration btw. if both are still in spec. It's the russians which differ a hair in focal length for nominal "50 mm" and need recalibration... of the lens, not the camera! NEVER recalibrate a western camera based on an unmodfied russian lens or you it will be off with all lenses made for it.

So useful. I will be calibrating my Canon 7 and your video will be handy! Many thanks!

Wouldn't f8 just make any error that isn't too much be compensated for?

Thank you so much, very helpful

Just the video I'm looking for, thanks a lot. Just bought a Canon & a realize when at infinity the focus patch is not aligned

Thanks for showing us how to calibrate ours canon 7 film camera

Very informative thank you

After vertical calibration, the vertical alignment goes off once I turn the lens out of infinity, any fix for it?

Not sure what I should be seeing and doing to actually calibrate. When at infinity should I only see one image? If I see a double image at infinity do I turn the screw or screws as needed so that I then see only one image, at which point the range finder is now calibrated?

Hry great video! Have you got the results yet?
