Tamron 90mm f/2.8 SP Di Macro VC USD Lens for Canon
Tamron has packed a lot of features into this lens for the price. The f2.8 aperture offers a nice depth of field while the 90mm focal length and minimum focusing distance of just under a foot offers a 1:1 reproduction ratio for life-size objects. The vibration reduction system will help reduce camera shake. The use of an internal focus system means that the length of the lens doesn't change as the camera focuses, which is a big plus when shooting macro. Tamron also included their Ultrasonic Silent Motor system, hybrid lens coatings and extra-low dispersion elements. This moisture-resistant lens weighs just over a pound.
