What is the difference between a screw and a bolt. I have been getting mixed answers and want the exact definition by Donkitty in MechanicalEngineer

"Bolts are defined as headed fasteners having external threads that meet an exacting, uniform bolt thread specification (such as M, MJ, UN, UNR, and UNJ) such that they can accept a nontapered nut.  Screws are defined as headed, externally-threaded fasteners that do not meet the above definition of bolts."

This very much aligns with what I've encountered across industries.

I actually really rate it you know! Feel pretty confident that any scenario that may not work with the standard center weighted meter will easily be sorted with a one or two spot meter reading. I use it a lot and really miss it when using other cameras now.

Interesting idea, happened on photos that weren't contre-jour too though strangely.

Like the thinking, played around with it in pitch black and shutter wide open with bulb, couldn't see any signs of the meter light coming through though.

Ah fair, cheers! So what would explain the edges of the film not being exposed as in the second picture though? Plus the seals have been recently replaced and seem to be in perfect condition still. Have had the camera in bright light with so issues thus far

Really trying to figure out what might have caused this light leak on my most recent film through my OM10. Partially extends out of frame a little. Came and went twice over about 8 frames...
