⭐︎⭐︎Canon Ultra-Wide Angle Lens RF 16mm F2.8 STM⭐︎⭐︎ I've entered Canon EF mount in the size selection because there isn't an option, but it's actually an RF mount. I'm selling this because I haven't used it much since I bought it. No box. Please refrain from purchasing if you are concerned about the condition as it is a used item.
