Physical switches freeze up when not used. Should they be lubricated? (focus switch, aperture, aspect)

i have not had that problem but i would not lub anything for fear of it working into the electronics. i take mine on long wilderness canoe trips and just use the small stiff brush that came with my hearing aid to keep the on/off switch clean.

I read somewhere that the cause for this is the glue used on the switch gumming up the knob. My fix is this: (1.) remove the plastic knob (2.) heat up the metal post on which the knob fits on with a lighter to melt off the glue (3.) use a drop of mineral oil or contact cleaner to lubricate the knob. This worked fine for me on a Saitek switch panel.

I have not noticed any blurry images. As to switching issues, I haven't used it for very long but don't remember any and I go between 4 sources.

Dont know if its too late to answer this to you... but I did fix it myself just sticking a piece of dark tape on the lateral... just over the round mirror found bellow the on/off switch. I did realize that it was sending some signals to the camera saying it was not night. Maybe some reflex from the white wall. So, I did tape it and now its working fine!

Non electrical, requires manual focusing and aperture control (aperture ring), also view finder gets darker

Haven't had that problem. The manual just says turn the camera off and check the connection. I'd worry that the lens electronics were damaged.

yes, I had the same problem after 6 months of owning the camera. With my camera, the lens froze open while after using the camera. I sent it to Canon while it was still under warranty and they fixed it. But I am worried that it will do the same thing again. I am really disappointed with this product!

I'll check with a thermometer later but it should be warm enough to notice. Also, it takes a few minutes to get rolling. I would suggest flipping the heat switch on and off about half a dozen times; the contacts may be oxidized if it was shipped through a moist location. Simply opening and closing the switch may be enough. I had the same trouble recently with some surge suppressors.

I had many problems with this myself. I tried to figure that out however was unsuccessful. I purchased other similar switches so I do not think I received a faulty switch. I would suggest YouTube.

Yes, mine froze up. So I lubricated it, but within a couple of months it froze up again. This has happened repeatedly, and it irritates me that it needs so much attention. A can opener should simply do its simple job without demanding all this loving care. So I'm back here on Amazon hoping to find a more reliable, less temperamental replacement.

I would presume that this is normal, as my 14-140 OIS switch is also the same way. Other than that, I think it is a terrific lens.

Yep. Keep it in my briefcase stored that way. I haven't left it on to see if it drains but I figure the "off" position on the switch is there for a reason.

I have not had any issues with this selector switching during use in manual mode. It has been a very reliable piece of equipment.

Sometimes the little trigger gets stuck. Look under the handle at the switch and see if you can manually press it in or out.

Try to fast click again instead of slow clicking, it's switching between light modes. Wish this still work.

My experience is that the DIP SWITCHES are upside down. Try reversing what you are doing.

I have the same problem. Seller is sending me a new flashlight. Don't know about just a switch.
