Kamlan 50mm F1.1 APSC Lens Overview
 
Versatile
Great street shooting lens, not too wide, not too long. On a APS-C sensor (any non-full frame camera body) it is also a great portrait lens, just long enough to remove distortion from your subject’s face and flatter them a bit more, not so long you need to stand across the street.

Fascinating Blur
Amazing maximum aperture of F1.1, which creates fascinating background blur effect and sharper image quality, even in weak lighting conditions

Great for Travellings
Because it’s light weight, and is a fast lens (big aperture f/1.1) the 50mm is a great addition to your bag for trips. It weighs practically nothing, you don’t even know it’s in there

Premium Optical Design
12 circular aperture blades, 5 groups of 5 elements lens structure with high quality multi-coated optical glass, ensures low image distortion, excellent image sharpness and great contrast. 50mm focal length is equivalent to 75mm on APS-C camera. Perfect for portraits shooting with fascinating background blur effect
