This is a used TTArtisan 11mm f/2.8 Fisheye lens (Sony E-mount). As a bonus, I will include a Canon genuine lens pouch LP814 that I was using for storage. Everything in the photos is included. I purchased it on Amazon in October 2022 for around 35,000 yen. I used it a few times for a fisheye request. I kept it in storage in case of future requests, but there were none this year, so I decided to sell it. It's a manual lens, but I think you can enjoy it by using the peaking and focus magnification features of Sony cameras. It is fully functional, and there are no scratches or mold on the lens, inside or out. There is a small spot on the metal lens hood (see photo 3), but otherwise, it is in good condition with little sign of use. However, please refrain from purchasing if you are overly concerned about minor imperfections, as it is a used item. I am not currently considering lowering the price. Thank you. ■ Main Specifications Focal Length: 11mm (35mm equivalent) Lens Construction: 7 groups, 11 elements (1 ED special low dispersion glass, 4 high refractive index low dispersion glass) Focus: MF (Manual Focus) Aperture: F2.8-F16 Aperture Blades: 7 Minimum Focusing Distance: 0.17m Filter: Not compatible Size: Φ67mm x 87mm Weight: Approximately 490g Compatible Image Sensor Size: 35mm full-frame Compatible Lens Mount: Sony E
