For Nikon Z mount (Although the size item says "Nikon F mount," this is because "Z mount" was not an option, and it is actually for Nikon Z mount) Focus ring color: Silver Serial number: 823111293 Included items: Original box, lens front cap, lens rear cap, instruction manual x 2 Everything shown in the first image is included. This is a 23mm f1.4 manual focus prime lens for APS-C cameras. Purchased new about six months ago. I am selling this lens because I sold my camera. I used it outdoors three or four times. There are no noticeable scratches or stains, but there are minor scuffs and signs of use from normal use. No mold or fogging. I couldn't tell with the naked eye, but there may be some minor dust particles (this does not affect shooting). It has not been exposed to water or impact. Stored in a dehumidified storage box. The infinity focus has been over-infinity since I purchased it. I will wrap it in bubble wrap and ship it via Takkyubin (Japanese courier service). No pets No smoking ⭐︎ I cannot offer discounts. ⭐︎ I will refrain from responding to comments asking for discounts. Focal length: 19-70mm Maximum aperture: ~1.4 Other features: With front lens cap, with rear lens cap
