I purchased this lens two years ago for astrophotography, but I've only used it twice, and it's in very good condition. I attached a lens filter immediately after buying it. The lens functions perfectly, but there is moderate mold on the rear lens element (this does not affect image quality, but please be aware of it) ⚠️ Please understand that this is a used item. - Brand: SIGMA - Model Name: 24mm F1.4 DG - Filter Diameter: 77mm - Included Accessories: Camera case (pictured in the 6th photo), lens hood, lens filter, front and rear lens caps Thank you for looking.
