ABSTRACT:
A camera is provided with a locking shutter speed dial device wherein the shutter release member is mounted coaxially with the shutter speed dial. A spring biased lock lever is positioned to engage a peripheral groove in the shutter release member. Engagement of the lock lever with the groove is accomplished by a pin mounted on the bottom of the shutter speed dial. When the shutter speed dial is rotated to the lock position, the pin urges the lock lever against the spring bias into engagement with the groove thereby preventing inadvertent operation of the shutter release.
