ProOptics collection 14mm F2.8 lens Canon EF mount

Product Name: ProOptics collection 14mm F2.8 lens Canon EF mount
Ultra wide angle lens for Canon EF mount. This is actually a rebranded Samyang lens for the US market. Made in Korea. It can be adapted to any latest mirrorless camera. Manual focus only with aperture ring and long focus throw for precise focusing collection. I have used this lens a few times for astrophotography and archaeology. See sample photos I took. The lens is quite sharp even at wide open with low coma. Very suitable for astrophotography. Infinity mark is not exact (a known issue to most Samyang manual focus lenses), but you can use a tape to mark it or use focus peaking as well as magnification from the LCD live view of your DLSR camera. When adapted to mirrorless, you can use the electronic viewfinder or both. The huge bulb like frontal element of the lens has some cleaning marks. They do not affect image quality. I have upgraded to Zeiss. So this one needs to go to make room.
