    Thank you for this stellar tutorial! I have a Spotmatic SP II and this worked a treat. I would like to add my 2 cents worth if I may... I was able to perform the repair without deconstructing the mechanism. I just used a Dremel mini rotary tool with grinding attachment! Hope this helps others going forward. Again thanks for your help :)

    Hello.
    I've had this problem too on my Spotmatic. The fix I made was to 1) sandpaper the L-shaped catch lever resting surface (with fine grain, to eliminate asperities). 2) Lubricate some gears and the axis of L-shaped catch lever that holds the mirror cam. This has been fine for about ten years now. So in my opinion, no need to risk a too deep modification like yours. However, I appreciate your input, this can be a solution if lubricating fails.

    I had a similar problem a few years back but I simply took the base off and used a minute amount of sewing machine oil and carefully placed it on the joints in this area, I got this idea by following the instructions from another You Tuber. The camera is still working fine.

      I did not watch this video to completion but as soon as it was mentioned to grind a piece down, I thought that should not be necessary. Agree to simply try lubrication and/or both cleaning and lubrication before grinding a precision piece down.

    Great video. I used this method and found that it helped but would still catch occasionally. I fixed the issue by ever so slightly bending the black component that the arm grabs onto. If holding the camera as if you taking a shot, I bent it towards the right (if that makes sense). Seems to be doing the trick.

    Great video. Fixed my 50 year old Spotmatic. There's also a fix for the obsolete battery. I used a Silver Oxide Duracell 390 battery. Since the metering system uses a current mirror, the battery voltage doesn't matter. The trick is you need to install it upside-down. The 390 was a bit large so slightly smaller diameter battery would fit without modifications .

    Interesting video 👍. Curious now as to whether it is a design flaw or not. The Honeywell Pentax i have earlier design (1964) has the hook arm design which nestles nicely. The Spotmatic F is 1973 i believe. I still have this issue so on and off so greasing now with special camera grease from Japan.

    If you think that Japanese engineers were so dumb that produced 5 000 000! of Spotmatics with faulty lever, just grind it. If not, take down the bottom of the camera, take it on the table by back, fill the syringe with needle with isopropyl alcohol and carefuly clean the wheels above the lever and all the mechanism, then cock it, shoot few times and repeat cleaning several times. let it dry, then use blower to clean it from free residues. when dry, take another syringe with fine needle, fill it with clock oil (or other oil for fine mechanisms), and take drop on every axle. do not overdose it. Take the bottom back and enjoy your Spotmatic.
    Why this happens - camera is 50y or more old, the original lubrication is dried, plus usually the sponge from the mirror is old and small pieces of it are all over the camera like dust. Together with the old lubrication it sticks the wheels, they move hardly with unsufficient energy to kick down the lever. PLEASE DONT GRIND THE CAMERAS, AND DONT LUBE THEM WITH WD40 AND ANOTHER CRAP, YOU ARE KILLING THE CAMERAS
