NiSi Ultra Wide Angle Lens 9mm F2.8 ASPH for Sony E-Mount

I purchased this last year but am selling it due to infrequent use.
It has only been used outdoors 4-5 times, so the condition is very good.
There are some minor scratches on the body, but they are not noticeable. (Photos included)

The body is made of metal with a high-quality feel, and the lens hood is also made of metal.
The focus ring is smooth and operates without any issues.

The image rendering is natural and has high resolution.
Distortion is minimal, making it an ideal lens for architectural and interior photography.

The official NiSi website lists the retail price at 60,500 yen, and it can be purchased by special order.

*This is a lens for APSC sensors.

[Product Introduction]

A 9mm ultra-wide-angle prime lens for Sony E-mount that achieves high resolution across the entire range and extremely low distortion.
The optical design, combining aspherical lenses and ED (Extra-low Dispersion) glass, corrects for distortion and chromatic aberration, which are common in wide-angle lenses, and achieves high image quality even in the peripheral areas of the lens. The 10 specially designed aperture blades create beautiful starbursts from F2.8 wide open. The minimum focusing distance is 0.2m, and the 113° angle of view captures dynamic landscapes. The 67mm filter thread allows for versatile filter usage.
