Cám ơn bạn, xP. Lens này là lens manual nên không thể chọn khẩu độ bằng máy được!
I'm aware of that fact. In M and by pushing the green button it will close down your aparture to the chosen aparture (e.g. you chose f5.6 it will close to f5.6 for a moment and measure the light and opens up again.
It worked for my 55/1.2 and for my M50/1.7 by removing the coating on the mount base. Not sure if it will work for K-lenses though.
