Performance:

• Distortion: Minimal distortion at 70mm, with some pincushion distortion at longer focal lengths.
• Vignetting: Noticeable vignetting on full-frame cameras, especially at wider apertures, but improves when stopped down.
• Chromatic Aberration: Well-controlled due to the use of APO glass, with minimal CA visible even in high-contrast situations.
• Autofocus: Fairly fast but can be noisy and may hunt in low light. The lens uses an internal motor for focusing.
