Performance and image characteristics

At larger apertures close to wide open, the lens emphasizes subtle subject nuances and produces warm color rendition that suits portraiture and casual snapshots. It faithfully captures delicate tonal shifts and fine detail.

When you stop the lens down to smaller apertures, for example around F4, it increases apparent sharpness and yields a delicate bokeh effect. Consequently, you can control both image clarity and ambience by selecting the aperture that matches your creative intent.

Additionally, the HD coating and the interior black coating work together to reduce internal reflections and color bleeding. As a result, the lens can clearly depict bright highlights while preserving subtle shading in challenging white or high-key subjects.

Built-in convenience

The extendible lens hood is integrated into the barrel. This design simplifies both light-shielding during shooting and storage when the hood is not needed.
