  • Excerpt: I used this lens for softball and baseball images. The build quality is excellent. For me the focus was very inconsistant. Some images were right on the money while other images were either front or back focused. At times the lens would not focus at all. I was very frustrated to say the least. I retured the lens and B&H made the process effortless.
  • Pros: Durable, Rugged, Strong Construction

  • Excerpt: Amateur - however did photography for a living several years It's a good build, solid lens. Reasonable weight, price and speed. A good balance. However the one fundamental disappointment with this lens is the poor resolution and sharpness. Did test shootings with the 1: 5,6/100-300mm USM, the 1: 2,8/70-200mm IS with Canon 1,4 TC and the Tamron !: 5,6/200-400mm using a Siemens test chart.
  • Pros: Lightweight, Rugged, Strong Construction
