Canon EF 100mm f/2 USM

ef100mmf_2usm_1_
Review Date: Oct 7, 2006 Recommend? yes | Price paid: $500.00 | Rating: 9 

Pros: Pros: - 10 pts, central to marginal sharpness: - 10 pts, contrast and color rendition, in Adobe RGB, despite the Kelvin degree of the light; - 10 pts, AF speed in medium to low light, even in AF Servo; - 10 pts, weight and handling; - 8.5 pts, build quality (front glass is too close to the extern barrel); - 8.5 pts, prints over 40cm; - 9 pts, overall quality of the pictures produce by this lens; - I like the discrete way it looks on the camera.
Cons:
Cons: - 6 pts, 7 blades diaphragm which produce poor backlight bokeh; - 7 pts, sever CA at the boundary of white or high reflecting surfaces when shutting backlight; - no hood in the kit.

Reviews about this lens have misleading me. My experience most with Zeiss lenses taught me that there is no universal lens. On digital, I use to shot with 300D, 350D, 30D and 1D.
Canon lenses: EF-S 18-55/kit; EF 17-40/4L; EF 70-200/4L, EF 200/2.8L; EF 100/2.0.
In short..., about 100/2.0 USM
Pros:
- 10 pts, central to marginal sharpness:
- 10 pts, contrast and color rendition, in Adobe RGB, despite the Kelvin degree of the light;
- 10 pts, AF speed in medium to low light, even in AF Servo;
- 10 pts, weight and handling;
- 8.5 pts, build quality (front glass is too close to the extern barrel);
- 8.5 pts, prints over 40cm;
- 9 pts, overall quality of the pictures produce by this lens;
- I like the discrete way it looks on the camera.
Cons:
- 6 pts, 7 blades diaphragm which produce poor backlight bokeh;
- 7 pts, sever CA at the boundary of white or high reflecting surfaces when shutting backlight;
- no hood in the kit.
Conclusion:
- lens dose the best job by shutting action on low light, but no far than 20m targets;
- very good on action at snow sports (ski, snowboarding, etc) if you carry the camera (that why I bought it);
- good on portrait (a little bit too sharp if the subject is over 30 yo)
Highly recommended.
