SIRUI 40mm T1.9 1.33x Anamorphic Lens for Nikon Z mount. (The only option available was Nikon F mount, but the Z mount is correct.) When used with a full-frame camera, APS-C crop mode will be enabled, resulting in a 60mm equivalent focal length. This lens produces anamorphic flares with natural colors. I purchased this lens about six months ago as an entry-level anamorphic lens and have been using it. The T1.9 aperture is excellent, allowing for easy shooting even after sunset. The autofocus, including face detection and subject tracking, performs with almost the same accuracy and speed as native still lenses, making shooting very easy even without a gimbal. I believe this is a very capable lens, offering excellent resolution and image quality for both video and stills. I have confirmed that the aperture and autofocus are all functioning correctly. While there have been no impacts or drops during use, there are some scratches that appear to have occurred while the lens was in my bag during transport. There may be some very minor dust particles inside the lens due to normal use (I apologize that the product images don't show the surface dust completely removed...), but I don't see any damage to the optical system (such as mold or haze). The original box, warranty card, case (unused), and front and rear caps are included. Please assess the condition based on the images. No claims and no returns accepted.
