I have the Sigma lens and i'm using it with a Samsung GX20 body.
It is a KA mount so should be able to use the Av mode and it works .. but i cant set the maximum aaperture of 3.5(at 70) .. the maximum i can set is 6.7.
Also the minimum i can set is 45 when it should be a minimum of 22 at 70mm.
Is there something wrong with the lens or is it normal for a KA manual lens?
Sorry if it's been discussed before but I searched and couldn't find something.
PS .. first MF lens i use :)
