Hi everybody,

On my recent trip, I've lost all the screws that attached the front element to the rest of the lens. It's just 3 tiny screws, I attached some photos where their placement is visible.

Unfortunately, I don't have any screws left to use as a sample to buy new ones. Does anybody know what type of screw was used in that place? Any idea how to find that information or an idea for a replacement? I tried googling but with no results, same with a repair shop in my area.

This looks like one of the later Mamiya-made versions. If so, it uses the same metric screw sizes commonly used in most Japanese lenses of the era. These likely had small washers on them to prevent rotation. You migth be able to scavenge similar screws from a Mamiya SX lens from the same era. The 50mm f/2 is extremely cheap.
