This is the SONY FE 40mm F2.5 G (SEL40f2.5G). I purchased it several years ago, but I'm selling it to organize my belongings as I haven't used it much. I've stored it with a filter attached, so there are no scratches or dirt on the lens. The lens hood is brand new and unused. I haven't taken it out much, so the body is also in good condition, but it is a used item, so please refrain from purchasing if you are looking for something in new condition. Name: FE 40mm F2.5 G Model Number: SEL40F25G Lens Mount: Sony E-mount Compatible Image Sensor Size: 35mm full-frame Focal Length: 40mm Maximum Aperture (F-number): 2.5
