Sigma 18-50mm f/2.8 DC DN Contemporary 鏡頭 (Sony E)

Switching from the kit lens to this f/2.8 constant aperture zoom is a night and day difference for low-light indoor shots. The 27-75mm full-frame equivalent range covers everything I need for travel and portraits.

Finally a zoom that doesn't feel like a brick in my bag, yet the 27-75mm equivalent range covers everything I shoot on a daily walk. The f/2.8 aperture handles low light way better than my kit lens ever could.

I’ve been using this lens for street photography and the constant f/2.8 aperture makes low-light shots incredibly crisp without bumping up the ISO. The 27-75mm equivalent range covers everything from tight alleyways to wider scenes, which is exactly what I needed.
