Input:
Like all Canon lenses, the optical quality is wonderful.  This lens has two settings, one for getting close, and one for getting even closer!  Easy on and off like all Canon lenses, works great with a Canon EOS T3i camera.  Recommend it to anyone considering a macro lens, much easier and better than using extender tubes!
