Compare Tamron A08 for Canon to Canon MP-E 65mm f/2.8 Lens

This is a new zoom lens from Tamron that lets you bring your far away subjects up close while compressing the distance between the main subject and the background for professional-looking results. Even while covering up to a 500mm that enables you to take ultra telephoto shots of subjects further than the eye can see, its design is extremely lightweight and compact. When mounted on an APS-C size digital SLR camera, it provides a focal length equivalent to a 760mm for super ultra telephoto imaging. 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.
