Pros & Cons
👍 Pros
- The 100mm fixed focal length is ideal for portrait photography, providing natural perspective and separation.
- Its wide maximum aperture of f/2 allows for excellent low-light performance and shallow depth of field.
- Equipped with a USM (Ultrasonic Motor) focus adjustment system, providing fast and quiet autofocus.
- The rear focusing system contributes to rapid and precise focusing without extending the lens barrel.
- A closest focusing distance of 0.9m (3 ft) allows for relatively close-up shots of subjects.
- Constructed with 8 elements in 6 groups, suggesting a well-corrected optical design for image quality.
👎 Cons
- The 100mm fixed focal length offers no zoom capability, requiring the photographer to physically move to frame shots.
- A maximum aperture of f/2, while bright, is not as wide as some other prime lenses available, which can be f/1.8 or f/1.4.
- The diagonal angle of view is limited to 24 degrees, which might be restrictive for broader environmental portraits or landscapes.
- Weighing 1.3 lbs (600g), this lens may add noticeable weight to a camera setup, affecting portability.
- Requires a specific Canon EF mount, making it incompatible with other camera systems without an adapter.
- The closest focusing distance of 0.9m (3 ft) may not be sufficient for true macro photography needs.
