I will lower the price at my discretion, so I am not accepting price negotiations. This is a listing for the SAMYANG 14mm F2.8 ED AS IF UMC lens and a NISI square filter holder set (150mm). Please note that this is a manual focus (MF) lens. I was using it without any problems on a D850 until recently. Some modifications have been made to the square filter holder. Even though it's a dedicated product, the corners were cut off, so I shaved off part of the hood to reduce vignetting as much as possible (please see the images). The exterior has no noticeable scratches and is in good condition. There is no mold or fogging inside the lens, and there are no defects that would affect photography. Included accessories are the front and rear lens caps, the original boxes for the lens and the holder.
