Power-up confirmed Shutter Bellows extension/retraction The above have been confirmed. Power is supplied via battery and AC adapter. The shutter fires, but when the shutter is fired with a lens attached, it takes a long time to advance to the next frame, and a "beep" sound is heard. (Probably some kind of warning sound?) Without a lens attached, the next frame advances without taking a long time. For some reason, the 120 film back cannot be locked, and cannot be attached to the body. There is a hole in the aftermarket bellows. After raising the finder loupe, when folding it back down, the locking mechanism does not retract properly, so it is necessary to use a flathead screwdriver to pull the mechanism. Due to the above conditions, please consider this item as junk, assuming it requires maintenance. ※ Please note that this is a used item, and I do not possess the specialized knowledge of a camera store, so there may be oversights.
