came across this company purely by accident ... what grabbed my attention was the 15mm f4 macro..... a true 1.1 macro watched a couple of videos in regards to lens and was very impressed they also have 60mm f2.8 ultra macro 2.1 , 105mm f2 macro and 12mm f2.8 wide angle zero-D (D for distortion )
name is Laowa lenses
