Image source: Anamorphic or Spherical: Which One’s For You?
Anamorphic lenses are designed to squeeze a wider image onto the sensor, then “unsqueeze” it later, which gives you a wider cinema-style frame, oval bokeh, and often horizontal flares. Spherical lenses project a normal, uncompressed image, usually with a more natural look, circular bokeh, and fewer optical artifacts. 1, 2, 3
Main differences
- Image shape: anamorphic captures a compressed image that is stretched back to normal in post, while spherical captures a regular image directly. 2, 3
- Look: anamorphic tends to feel more cinematic, with oval bokeh, streaky flares, and softer edges; spherical tends to look cleaner and more natural. 4, 1
- Aspect ratio: anamorphic is commonly used to reach wide formats like 2.39:1, while spherical is often cropped to get that look. 5, 4
- Practical use: anamorphic lenses are often heavier, more expensive, and can lose some light; spherical lenses are usually simpler, sharper, and easier to work with. 1, 2
Which to choose
If you want a stylized, widescreen, “film” look, anamorphic is usually the choice. If you want maximum sharpness, flexibility, and a more realistic image, spherical is usually better. 6, 7, 4, 1
A simple way to think about it: anamorphic is for visual style, while spherical is for straightforward image capture. 2, 1
