Sigma 50mm f/1.4 DG DN Art Lens (Sony E)

This appears to be a description of a high-end camera lens, specifically a prime lens. Here are the key features:

1. **Full-Frame**: The lens is designed for use with full-frame sensors, which means it can take full advantage of the camera’s sensor size and resolution.
2. **Fast aperture**: The lens has a wide aperture range of f/1.4 to f/16, which allows for a shallow depth of field and a high level of light transmission.
3. **Compact and lightweight**: The lens is described as “fast” and “compact”, suggesting that it is relatively small and portable compared to other lenses with similar specifications.
4. **HLA Linear Focusing Motor**: The lens uses a High-Low-Acceleration (HLA) motor to drive the focusing mechanism, which provides smooth and quiet autofocus performance.
5. **Aspherical & SLD Glass Elements**: The lens incorporates aspherical elements and Special Low Dispersion (SLD) glass elements to reduce distortion, chromatic aberration, and spherical aberration, resulting in improved image quality.
6. **Rounded 11-Blade Diaphragm**: The lens has an 11-blade diaphragm with rounded edges, which helps to create a smooth bokeh (out-of-focus area) and reduce the likelihood of harsh transitions between in-focus and out-of-focus areas.
7. **Dust & Splash-Resistant Design**: The lens has a design that is resistant to dust and moisture, making it suitable for use in harsh environments or during outdoor shooting.
