Sigma 20mm F1.4 DG HSM Art

Prime lens | Canon EF, Nikon F (FX), Sigma SA Bayonet, Sony FE

I purchased this lens about a year ago but was busy with some projects so didn't get to fully test it out for a few months. When I did I was not so happy with the focus.

Hi I received my lens a few days ago and already love it. We do not have much light here in the arctic right now so all my shots are low light but that is what I bought it for.

The lens cap was split on arrival so you pay for a trade off with sigma somewhere. It is not the only lens I have from them that has bad ...
