Canon EF 100-400mm f/4.5-5.6L IS USM

Review Date: Dec 25, 2007 Recommend? yes | Price paid: Not Indicated | Rating: 9 

Pros: Very sharp, contrast, and good colour
Push pull zooming system, no lock switch for push pull zooming, AF point not suitable for 2x TC

I sold my great Sigma 70-200 f/2.8, Tamron 11-18, and sharp Tamron 28-75 f/2.8 plus 400 US $ for getting this amazing sharp of Canon 100-400 L IS lens. I'm very happy with the result : very sharp, contrast, and good colour besides the zooming range.

In zooming range 400 mm, I tested with shooting a tower for distance about 1 km and compare with my Sigma 70-200 mm plus 2x TC. The result of this Canon lens is very amazing : very sharp and there is no CA detected. The Sigma 70-200 is great and amazing lens in 200 mm range but with 2x TC the CA was detected.

Combine 100-400 Canon lens with 2x TC is not good idea, the result is bad sharpness and rather blur colour, especially in low light. Sometimes I found that IS using is not better than without use it in sunny light.
