Sigma Art 50mm f/1.2 DG DN 50mm
Weighing just 745g, this is the lightest f/1.2 autofocus 50mm in its class, using dual High-Response Linear Actuator motors for fast, quiet focus. Its 13-blade diaphragm and four aspherical elements deliver smooth bokeh with high contrast, aided by a dust- and splash-resistant build. This lens is best for portrait and wedding photographers who need extreme subject isolation in a portable, weather-sealed package.

What owners think
How owner sentiment changed over time
ExclusiveBased on when customers actually wrote their reviews - so you can see whether early praise held up.
- Q1 202543/100
Mixed reviews: one buyer loves it as a sharp value lens; two find softness wide open with cluttered design.
- Sharpness wide open is contested: one finds it razor sharp, two say soft until f/1.8.
- Cluttered aesthetic with excessive text and branding on the lens barrel.
- Compact size and silent, quick autofocus praised.
- Value for money: seen as a budget fast-aperture lens, not for high-end print work.
- Q2 202490/100
Buyers praise the Sigma 50mm f1.2 as a Noctilux alternative with sharp images, creamy bokeh, and fast AF. One notes a slight rattle when off, but it tightens on power.
- Noctilux-like image quality at f1.2 with crisp microcontrast and creamy bokeh.
- Lightning fast, accurate, silent autofocus on Sony bodies.
- Heavy (2.9 lbs) but manageable with A7CR grip; cradling lens helps.
- Slight rattle when camera off and tilted; tightens when powered on.
