Canon EF 100 mm f/2.8 Macro USM

11. Summary

Pros:
  • excellent image quality in the frame centre and at the frame edge at all apertures,
  • negligible chromatic aberration,
  • distortion at practically zero level,
  • very low coma,
  • moderate astigmatism,
  • silent and relatively quick autofocus,
  • good build quality.

Cons:

  • autofocus could have been more accurate.

I like testing such lenses very much. The test procedures and the results analysis go smoothly and efficiently. I don’t have to think what went wrong and why, describe all slip-ups in detail, find arguments why a lens is overpriced. Here everything went almost perfectly. For the sum of about 640 $ we get a well-made instrument with excellent optical and mechanical properties which is ideal for macro photography and portraits as well.

It didn’t break any records like the Tamron 2.8/90 Macro but it fared much better by f/2.8 and f/4.0 and had a significantly lower chromatic aberration than that lens. The Tamron is cheaper but it has neither inner focusing nor an USM motor. The Sigma 2.8/105 Macro is a similar case. It is not equipped with an ultrasonic autofocus and it changes its dimensions on focusing, its image quality is very good and the chromatic aberration – low. It is also cheaper than the Canon. As you see, in the 90-105 mm macro class the choice is wide – each and every of these three lenses can make even a demanding user satisfied with the results. Which lens you decide to buy is only a matter of your personal tastes and your pocket.
