    I found an old Konica rangefinder at my thrift shop. Everything works good but the sticky shutter. I cleaned it with rubbing alcohol and it worked good after that , but now it is stuck again. What should I lubricate it with? A little drop of WD40?

    I would be careful with it. Maybe apply it with a Qtip so you can control where it is. Make sure not to get any on the lens or the aperture as this may have an adverse affect. But since it's a thrift store special go for it. Just be careful.

    WD-40 is the last thing I'd use I don't know the best but I would think it would be a silicone or graphite lube.

    Yeah, I'm not sure why they even manufacture WD-40. I keep hearing all these stories about how bad it is for everything you'd want to use it on, like bike chains, folding chairs, doors, anything with non-metallic parts, etc.

    WD-40 has some really good uses. If you were to soak your bike chain in it it would get rid of a lot of the rust and dirt. It would also thin down the grease so that it is useless. Basically it should never be used as a lubricant per se but more to unstick parts that are dirty/rusty.

    Water Displacement. Works great for getting a wet alternator working again.

    Absolutely not. Never use WD40 on any camera. Don't put any lubricant on
    shutter blades. The reason they are stuck is because lube has gotten onto
    them from elsewhere. And, rubbing alcohol should not be used on shutters
    or anything inside the camera as it contains water and will leave a residue.

    The best solvent for shutters is naptha which can be easily found as
    Ronsonol lighter fluid. Apply with small bits of tissue soaked in naptha
    repeatedly and wipe with dry tissue to remove the the dissolved lube. The
    naptha will evaporate quickly and leave no residue of its own. Repeat until
    the blades are clean and the shutter works freely. Do this on both sides
    of the blades if possible.

    Ideally the shutter should be removed and disassembled for thorough
    cleaning but cleaning in place often works if you are patient.

    Which model Konica is it?

    WD40 is good as an attractant when sprayed on fishing bait. Don't know where my head was last night, though.

    WD40 is used in the movie business by stunt people. Those car chase
    scenes where you see the tires spinning and smoking widely are done by
    spraying the tires with the stuff.

    Ronsonol will clean the blades. It will take a number of q-tips and many shutter clicks to get it totally clean. Blades are to be totally dry in cameras, no graphite either. The S2 is known for play in the lens barrel. As long as the focus is OK, leave as is.

    There are about 5 wires that attach to the battery compartment. These can be corrodes. Plus the CDS cell is known for being weak as the cameras age.
    If pushing the button makes the meter go high, then it probably has a weak or dead CDS cell.

    The wires that connect to the cell on the S2 often develop bad connections
    and sometimes come loose. It's pretty easy to get to the cell to check
    that. If loose or corroded, they can easily be cleaned up and re-soldered
    with a fine tip iron.

    The Auto S2 is a fine picture taker with a very sharp lens and an excellent
    viewfinder/rangefinder.
