A quick guide to MTF charts (which only measure contrast and resolution. Canon's guide to their MTF charts) Black lines reflect lens performance at widest aperture. Blue lines show the performance at f/8 Thick lines indicate lens contrast Thin lines indicate lens resolution Dashed lines: Lens performance with meridional lines. Solid lines: Lens performance with sagittal lines Closer sagittal and meridional chart lines indicate more 'natural' out of focus areas. Remember that MTF charts are good for comparing similar lenses, so comparing ones from the 14mm f2.8L and 300mm 2.8L won't tell you much at all, whilst comparing the EF14 2.8L with the EF14 2.8L II will show meaningful differences. Note that other manufacturers may have different ways of displaying such information that may or may not match up with the Canon figures.

The EF70-200mm f/4L IS USM Lens - Versatile and Compact New EF Lens

Canon is also the only manufacturer to provide a full range of professional zoom lenses in both the high-speed f/2.8 category as well as the compact and lightweight f/4 category. Rounding out Canon's f/4L lens lineup is the new EF70-200mm f/4L IS USM lens. This "L" series lens is designed for professional or advanced amateur photographers seeking maximum performance and versatility. This is a lens that can handle almost any assignment, ranging from distant subjects to the demanding requirements of up-close and personal portraits as well as nature photography.

The EF70-200mm f/4L IS USM lens stands up to the rigors of professional use The lens is sealed from dust and moisture, and is equipped with the latest generation of Canon's Image Stabilizer (IS) technology, making it an optimal everyday shooter. The image stabilization achieves three shutter speed steps of camera shake correction within 0.5 seconds after the shutter button is depressed halfway and yields correction for up to four full shutter speeds while handheld, providing a new level of performance. Users can also select two IS modes, one for stationary subjects and another for intentional panning.

The EF70-200mm f/4L IS USM lens is the same size as the EF70-200mm f/4L USM lens that remains in the EF lens line, but the new lens adds several valuable features. In addition to enhanced weather sealing and image stabilization, the EF70-200mm f/4L IS USM lens incorporates a circular diaphragm to create more natural looking background blur, and distance information to aid autofocusing and automatic flash exposure. The lens also suppresses flare and ghosting with advanced coatings and optimal placement of its 20 lens elements in 15 groups. One Fluorite element and two UD (ultra low dispersion) elements thoroughly suppress chromatic aberrations for crisp photos throughout the entire focal range. A ring-type Ultrasonic Motor (USM) provides fast and silent autofocusing, while the full-time manual focus function provides maximum control even when the lens is set for AF.

The compact and universal EF70-200mm f/4L IS USM will also be available in November for an estimated selling price of $1,249.**
