二手 Sigma 16mm f1.4 DC DN Contemporary 鏡頭 - Canon M

The f/1.4 aperture is a game-changer for indoor portraits—even at ISO 400 I’m getting crisp, creamy backgrounds without touching a flash. Autofocus has been snappy on my Canon M, and the used condition honestly looks and performs like new.

I’ve been shooting night street scenes with this lens, and the f/1.4 aperture lets in so much light that I barely need to raise the ISO. The autofocus is snappy on my Canon M body, and the wide 16mm gives a really cinematic look.

Bought this for indoor concert shots and the f/1.4 just swallows light—finally getting sharp frames without cranking the ISO into the stratosphere. Focus ring feels a bit looser than a new one, but the autofocus is snappy and the shallow depth of field is exactly what I wanted.
