What about fully electronic shutters? they don't use springs as a rule. I fully agree with him about manual shutters that they do have springs and leaving them cocked and under tension was not a good idea.
It is the same with any mechanical item using a spring. When I was in the army we used 7.62mm rounds in the British Army standard rifle from the 60's to the start of the 80's and we were taught not to leave a full magazine of 20 rounds in all day unless we were firing, but to empty the magazine out, relax the spring and then reload at least every 24 hours. That helps prevent unexpected and unwanted stoppages.

Are the 1/500 & 1/250 speeds of the Nikon F2 considered the fast or very fast speeds Sover Wong mentioned…?
It may depend on the camera. Hasselblad cameras and lenses are specifically designed to have the shutters cocked when stored. I do not know about the rest.
Many electronic shutters do have springs. Any horizontal-travel electronic shutter will have springs. This includes the Nikon F3, Olympus OM-System cameras with autoexposure and cloth shutters, Minolta X-Series, and Leica M7. The vertical-travel metal multiblade shutters in cameras like the Pentax ME, Canon T90 and EOS cameras, Nikon N-Series, Minolta Maxxum, etc. didn't use springs.

It would seem that they are, but Mr Wong is the only one who can provide the answer.

The tempest in a teacups, has passed. 1/250 and 1/500 are ok for NIkon and Hasselblad lenses are design to be stored in the cocked configuration. Now only the Canon and Leica owners will not sleep tonight.

Weak spring in a horizontal FP shutter will affect all speeds. Even the slow ones like 1 second, because the force against the escapement is less, it will take longer to go the distance and end up being longer than 1 second. Good news is there is frequently a wide range of adjustment of the springs. More likely than not, in my experience, a stored camera with a slow horizontal FP shutter will be due to gumming with old lubricant dirt, oxidation, etc., irrespective if it was left cocked or not.
Isn't the shutter in any camera that has auto wind always cocked? Whether P&S or SLR? Or anything in-between?

My question was pertaining only to the Nikon F2…!
No Huss, with most S.LRs you can remove the winder or motor drive then fire the shutter, before you put the camera away which is what I do with my Canon F D cameras.

So far as I’ve read and understood the descriptions of shutters used in FILM CAMERAS, whether mechanically timed or electronically timed, they are all actuated—both opening and closing—by one or more compressed springs. That includes the electronically timed versions of the various models of the vertical traveling Copal SQ focal plane shutters and the Seiko #1 electronically timed iris shutters found in Mamiya RZ67 lenses. For example, the electronically timed shutters in Nikon SLR film cameras are all spring actuated.
The springs in question are usually in a tube on the left side of the shutter opening. Unique to the F2, the closing curtain springs are naked and not enclosed in a tube. You can see in this Nikon factory diagram. Metal vertical shutters are an entirely different design and spring configuration.
I know, but the thread digressed a bit. Sover stressed not to leave the camera cocked, and Leica says the same thing about their film Ms.
Sorry, I meant with cameras that have built in winders. eg F100, F6, any AF slr etc.
Sorry I know nothing about A/F S.L. Rs , except I once test drove a Nikon F 6, and it was as heavy as a 6x4.5 medium format camera, and if I was able to lug that weigh about I would rather have the bigger negative.
I feel the same way. I once picked up a 6x4.5 camera and thought, if I was going to lug that weight around I'd much prefer a camera with AF, motor drive and gets 36 exp per roll.

Sover and the Nikon F2 manual clearly states, don’t leave the F2 cocked for more than 12 hours...!
