There were some leaf-shutter cameras which had an exposure value lock so that changing either speed or aperture would change both at once.

cameras today easily do that, and have for years.

I wonder how many serious amateurs have used that feature, except when using auto ISO.

nospam
probably most, if not all of them.

anyone who uses p/s/a modes did.

PeterN
Nope. Most that I know and shoot with use either aperture preferred, shutter preferred, or manual. They rarely use program mode.

nospam
then it's good thing i listed s and a, isn't it?

the point that you obviously missed is that in any of those modes, adjusting either the f/stop or shutter speed, will automatically adjust the other to compensate.

in manual mode, it won't. that's why it's called manual mode.

PeterN
The choice depends upon the subject matter and desired image. If you want to shoot program mode, that;s your choice.

nospam
you don't say.
