Here’s the info from the campaign about the new Kalman 50mm f/1.1 MK2 lens:
“We are Machang Optics with central focus on providing cost-effective large aperture lenses with high quality for every shutterbug and letting everyone enjoy the fantasy of large aperture lenses. It has always been our mission and main goal. With the success of the 50mm F1.1 and our first Kickstarter campaign of 28mm F1.4, we’ve received a lot of feedback from backers and customers, especially the 50mm F1.1, a controversial lens with both compliment and criticism. We cherish them all and turn them to the power that drives us to move forward.
As portrait photographers ourselves, we usually face the problem of not being able to get both great sharpness and creamy bokeh. To be honest, it’s really hard to achieve a good balance between them. 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 a safe shutter speed in extreme low light conditions and also the ability to create beautifully creamy backgrounds. Brand new optical design ensures great sharpness from wide open to stop down.
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 aperture lenses, it does not introduce too much color cast to images but delivers a neutral, accurate color rendition even wide open. You can easily create a great 3D effect and great sense of atmosphere for your images.
Balance is the main design concept of the Kamlan 50mm F1.1 MK2. Unlike most large aperture lenses with spherical aberration when shooting at close distance, Kamlan 50mm F1.1 MK2 features with dual high index of refraction element groups. It can calibrate the spherical aberration effectively. As a result, your images will be sharp from shortest distance to infinity.
