Sigma 28-45mm f/1.8 DG DN Art 鏡頭 (Sony E)

Shot some portraits last week and was blown away that I could zoom between 28 and 45mm without losing the f/1.8 aperture. The ring action feels smooth, and the sharpness stayed consistent across the whole range.

The constant f/1.8 aperture across the whole zoom range is what sold me—shooting indoors at 28mm and then zooming to 45mm without losing any light feels like magic. It’s heavy, no doubt, but the image sharpness at wide open makes me forget the weight every time.

This F1.8 constant aperture across a zoom range is a game-changer, and the sharpness on my Sony body is unreal. I've been able to shoot indoors without a flash and still get crisp, professional-looking portraits.
