Introduction

Canon EF 100mm f/2.8L IS USM is the newest addition to the manufacturer's lineup of macro lenses, and is the second 'Pro' grade (or 'L') classified macro lens besides the EF 180mm f/3.5L Macro USM. The lens is derived from the EF 100mm f/2.8 Macro USM, which was released back in 2000 and is the first Canon macro lens to incorporate an Image Stabilization technology. Moreover, this is also the first lens to incorporate the newest Hybrid IS system (everybody is jumping on the 'Hybrid' bandwagon these days, whether it makes sense or not), which is said to compensate for both angular and shift camera shake and is operational at all focusing distances, including macro. The lens was introduced in mid-2009 and is currently priced at ~US$1,050.

The build quality of the lens is very similar to that of other L lenses - it can't really compare to Leica or Carl Zeiss precision manufactured and polished, all metal bodies, but is significantly better then your typical consumer grade lens. The barrel is made of hardened plastic, and while it does not look too flimsy, if you tap on it with your fingernail, you'd be immediately convinced that the barrel will not be able to withstand too heavy abuse. The optical construction of the lens consists of 15 elements in 12 groups, including a single UD element. The lens weighs 625g (22oz) and measures 77.7 x 123mm (3.1 x 4.8in).

As with the previous model, Canon EF 100mm f/2.8L IS USM incorporates a silent ultra-sonic type motor and support both AF as well as full-time manual focusing. The lens sports inner focusing system, meaning that the size of the lens does not change during focusing. his is a 1:1 lens, meaning that at its minimum focusing distance of 30cm (0.99ft), you will be able to achieve life-size subject magnification. The lens accepts 67mm screw-in type filters.

Considering that the EF 100mm f/2.8L IS USM Macro is designed for full frame cameras, when used on APS-C type bodies with 1.6x crop factor, the field of view of the lens will resenble that of a 160mm prime on an FF body. The factory box includes Canon EF 100mm f/2.8L IS USM Macro lens, front/rear caps, ET-73 lens hood, LP1219 soft case, registration and warranty cards.
