Camera Shutter question~?

Question: Camera Shutter question~!?

I've llearned about 3 different types of shutters (in a camera)!.
Leaf Shutter (circular -closing into the center-etc!.)
Focal Plane Shutter (two curtains moving across the focal plane- directly in front of the film)
AND!.!. A third one that moves from top to bottom!.!. But I can not remember the name!.!.!.

So, does any know the name of the shutter that moves from top to bottom!?

Thank you in advance!Www@QuestionHome@Com

It's still a focal plane shutter, but just a vertical travel shutter instead of horizontal!.

I KNOW there's another name for this, as I remember when they were introduced (yes, I am really that old) and they were called SOMETHING else!. I asked a very similar question here about 6-12 months ago and I didn't get any answer other than focal plane shutter!.

"Copal" is a common name for leaf shutters, by the way!. It's a brand name that is very commonly used!. "Compur" is another!.

There are some people here saying that is was called the "Copal Square" shutter, but I can't substantiate that beyond their comversation!.

It's still a focal plane shutter, but just one that moves horizontally rather than vertically!.

Dr!. Sam,
I'm pretty sure that what you're asking about is indeed called a Copal Square shutter!.

It was used on the various Konica cameras, as well as on the Canon EF, among others!. At the time, it was a pretty big deal as it could sync at 1/125 when most horizontal shuttered cameras did 1/60 at their best!.

The shutters used in pretty much every modern SLR these days are derivatives of the Copal square design!. Many, however, are improved to sync at 1/250!.

Interestingly enough, the Canon F-1N is the fastest syncing horizontal shutter I know of!. It can sync at 1/90!. It was also the last major camera I'm aware of to use a horizontal shutter design(using titanium foil shutter leaves)!.Www@QuestionHome@Com
