Transform everyday scenes into extraordinary moments.
The SG-image 50mm F1.8 Phantom Lens is the world’s first* lens to feature a built-in variable shape aperture system, with four unique aperture plates: Heart, Snowflake, Oval, and Star. Designed with an optical structure of 7 elements in 5 groups, including 3 high-refractive elements, it delivers outstanding optical performance and expressive rendering of light and shadow.
This innovative lens is perfect for various photography situations and is built with a durable metal body and a smoothly operating focus ring for excellent handling and longevity.
In scenes where you'd normally get round bokeh, this lens allows you to enjoy creative bokeh shapes such as Heart, Snowflake, Oval, or Star for a more artistic touch.
With four aperture plates built into the lens, you can switch between different bokeh effects without needing separate accessories.
Simply rotate the control ring to change between the four patterns on the fly, letting you match your bokeh style to the scene or your creative vision.
