Thank you for viewing. Although the details are unclear, this is a 4x12 monocular for sale. It's stated that it can achieve 40-120x magnification when used with a Z50. After researching online, it seems there's a telescope model with the Z50 designation, and it appears to increase magnification when attached to the eyepiece. The items for sale are the monocular itself, a strap, front and rear caps, and a dedicated case. It's practically unused, but it is still a used item. Please consider this before purchasing. #sunacamera
