Originally posted by niceshot No WD-40, IT will cause the shutters to dis attach themselves. There is 2 shutter adjustments at the bottom of the camera, the one closest to the mount is the closing shutter adjustment. Maybe if you tighten it a 1/4 of a turn it will solve your problem . Do It @ your own risk. no more than half a turn.
Oh, I've worked with enough small mechanical parts and electronics to know how bad WD-40 is for "lubrication" - that will gum things up in no time! Some things it dissolves, nah. It's good for, well, water dispersing but inside a camera? No no no no nope.
I hope just cleaning things with mild solvent (rubbing alcohol, lighter fluid) and then a few very small drops of light machine oil (sewing machine was recommended, that's probably good) will do the trick. If it seems things need more actual adjustment than that, I'll probably send 'er off for a professional CLA. Or buy a non-working body to experiment and learn on.
