Compare Canon TS-E 45mm f/2.8  Lens to Canon MP-E 65mm f/2.8 Lens

Cannon offers this normal lens featuring tilt and shift movements. The floating system and rear focusing give sharp and stable delineation from 0.4 m to infinity. The 45mm focal length is ideal for obtaining a natural-looking perspective. Less

This lens, used alone without attachments, performs macrophotography from life-size to 5x magnification. This lens offers much better portability and operability for outdoor high magnification macro photography of flowers, insects, etc., than conventional bellows systems. The optics uses a 3-group floating system, which moves three lens groups independently for focusing. This compensates aberrations caused by the large changes of image magnification inherent in macrophotography, while achieving high magnification from life-size to 5x and a fast f/2.8 maximum aperture. A UD (Ultra-low Dispersion) glass lens element corrects chromatic aberration, which is often a problem in high-magnification macrophotography, and achieves a high-resolution and high-contrast image without color fringing.
