    Excellent video. So many of these fixit videos provide too much information or too little. Yours is the perfect balance.

    This and your other 35mm f2.8video were a huge help in cleaning and adjusting the infinity focus on a slightly newer version of this lens. Thank you!!

    Interesting, I just took apart my W. Rokkor HG MC1 and it didnt have spanner notches on the inside after taking the front element out, instead the front ring and the aperture blades was held by JIS screws. Was able to clean my sticky aperture blades, but did have them fall off before figuring out how to get it back together oops lol.

    I was hoping to see how you cleaned the oily blades individually. Perhaps you could make a new video on that part that was missing from this video.

    Hello, and thx so much for your video. I own that lens that I bought recently (exact same model, checked twice) and after an almost full disassembly of the lens (focussing ring was stiff) I tried to zero the lens as you say. Everything goes fine except that when I loossen up the three screws, the focussing ring does NOT become indepedent of the focussig mecanism, and that because I assume that on my lens those screws have in fact a specific position that you can never change. How is that possible?
    Have you any idea?

    The dust it can be in between the optical elements, or usually just at the bottom?

    How do you keep the lens elements from becoming misaligned when re-assembling the lens? I have a lens that needs disassembling, but am afraid of misaligning any elements.

      +Michael Soo For this type of lens, alignment is more of a concern if you separate the lens groups themselves by de-bonding the elements. Just disassembling the lens should be ok, especially if you just remove the optical components as complete units to access the diaphragm or body sections.
      If you do take apart the optics, without an optical bench, your best bet is noting where everything lines up before taking apart the lens and matching this on reassembly. I would only recommend this if there is a serious problem because it's easy to make things worse (I don't show this step in any of these videos for that reason).
      The optics should lock into fixed positions in the body and the tolerances for how the optics fit should be small. The reassembly probably wont be perfect, but how good was the optical alignment on a fifty year old lens that's been banged up to begin with? If you want perfect, send the lens to a high-end repair shop.

    What is the cutting mat on background?

      Not the best work station mat actually since it absorbs oil and grease, but nice enough to look at in the videos.
