Canon 100mm EF f/2.8 Macro USM Lens
| January 18, 2012 | Posted by admin under Canon Lenses |
The Canon EF 100mm f/2.8 USM is one of two Canon 100mm macro lenses currently on the market, the other being the more expensive image-stabilized L-series optic, which costs a far less affordable $1100. This lens focuses down to 1:1, and contains an internal focusing system that maintains the same working distance throughout its focusing range, as well as keeping the front element static as this happens.
The lens has a ring-type Ultrasonic Motor, which delivers fast, quiet and accurate autofocus, while the inclusion of a three-group floating system is designed to correct lens aberrations throughout the focusing range.
You’ll find a particularly broad manual focusing ring on the barrel, which turns smoothly and makes it clear when the ends of its focusing scale have been reached.

The saturation and general color is amazing.
A focus limit switch limits the focus range to reduce ‘hunting’ and improve autofocus speed, and enables the user to quickly block off the closer end of the focusing range when shooting non-macro subjects.
Minimal distortion
Control over distortion is good, and the absence of chromatic aberration in the centre of the frame is particularly impressive. Central sharpness at f/2.8 is also impressive and at f/8 it is one of the sharpest macro lenses on the market, right across the frame.

Sharp, versatile and a bargain
