Sigma 適馬 16-300mm f/3.5-6.7 DC OS Contemporary 鏡頭（L-Mount）

That three aspheric lens design really cleans up the chromatic aberration, I’ve noticed much sharper edges on my landscape shots compared to my old zoom. It’s impressively quiet and fast for a lens with this much range.

I was worried about chromatic aberration with such a wide zoom range, but the three aspheric lenses really keep things sharp from corner to corner even at 16mm.

Took this out for a weekend shoot and the sharpness across the whole zoom range genuinely surprised me—those three aspheric elements are doing serious work. Chromatic aberration is basically a non-issue even wide open, which is exactly what I needed for landscape shots with harsh backlight.
