Focal Length (Wide)...13-18mm Focal Length (Telephoto)...36-50mm Maximum Aperture...4.1-5.6 Other Features...Junk I purchased this as a used, good condition item, but the collapsing mechanism is broken, and the lens does not move from the state in the image, even when the zoom ring is turned. (Tears) I will sell it at a low price, so how about it for those confident in repairs or for parts? It cannot be used as a lens in its current state. There are no unusual noises when shaking the lens, but there may be internal damage or contact misalignment. [Mount] CANON RF Mount (I have selected EF because there is no RF option on Mercari, but it is RF) [Item Condition] As mentioned above, the collapsing mechanism is broken. The lens extension does not change from the state in the image. Storage position: Does not collapse. (Image 4) 18mm: There is a clear click feel. (Image 5) Around 28mm: There is a snag. (Image 6) Around 35mm: There is a clear click feel. (Image 7) 45mm: Stops. (Image 8) The lens is extended, but the camera does not recognize it, so the shutter does not respond even when pressed. (Image 9) [Appearance] There are scratches and scuffs. [Optics] I think there is no mold or scratches. [Included Items] None. Only the main body in the first image. I will protect it with bubble wrap and ship it. Please consider purchasing only if you understand that this is a junk item.
