This is the Mamiya waist level finder for the 645 Super, Pro and Pro TL. It does not fit the m645 cameras. It is a great accessory, particularly for landscape photography. It makes the camera significantly smaller and lighter, important for backpacking, and lets you step back and look at the image, leading to a more contemplative and thoughtful style of photography. I also find that it is easier to focus critically with the pop up magnifier.

The unit is lightly worn and works perfectly. It comes with the bottom cover.
