The “Kamlan 50mm F1.1 MK2 APS-C lens” has a super large, bright f/1.1 aperture with 11 circular aperture iris that allows for great results in extreme low light conditions and also the ability to create beautifully creamy backgrounds. Brand new optical design can help you get great sharpness in all aperture range.
One of the key strengths of the Kamland 50mm f/1.1 MK2 is its high degree of color accuracy and richness. Unlike some normal large lenses, it does not introduce too much color cast to images but instead delivers a neutral, accurate color rendition even wide open. You can easily create great 3D effect and rich sense of atmosphere for your images.
Kamlan 50mm F1.1 MK2 features with dual high index of refraction element groups. It can calibrate the spherical aberration effectively. The result is your images will be sharp from minimum distance to infinity.
Further extending the flexibility of the lens is the ability focus down to just 0.4m (1.3ft), allowing you to fill the frame with your subject and throw the background dramatically out of focus.
Kamlan 50mm F1.1 MK2 features a larger diameter element with high index of refraction glass to help eliminate the onion rings. The whole defocus area is smooth and creamy.
