DxOMark reviewed Sony FE 28mm F2 lens, this little and cheap wide angle lens for Sony e-mount!
Let me give you the coclusion:
Ranking third for all hybrid lenses, just behind two significantly more expensive Carl Zeiss options, is a great result for the Sony FE 28mm F2 lens. At a cost of just $498, and boasting a “fast” F2 aperture and solid results in most categories, it’s an affordable wide-angle solution for Sony A7 series shooters. It’s actually marginally ahead of the Zeiss wide-angle competition overall for sharpness, but isn’t quite as strong at F2.8, where the corners drop off a little. The main area of concern is Distortion, however, with quite heavy “barrelling” that landscape and architecture photographers will want to correct in post-production.
