Performance & handling Prime lenses are about as simple as can be in terms of handling. You have just two controls – the focus ring and (depending on your lens mount) the AF/MF switch.

The contrast between the sharp and the blurred is often overlooked by still photographers as a creative tool, but it's often used very effectively by cinematographers.

Big glass that lets in lots of light!

A bit on the heavy side; but really no problem

This is the first Sigma 50mm f/1.4 prime lens for 4/3 DSLRs, a tele photo lens in the focal length of 100mm equivalent to portrait lens in medium distance. A superb lens of optical quality and design, fast focus in silent with HSM.
