A review of the Fujinon 100-400 against the Canon 400f5.6L |  Robert W. Baron

Long time Canon shooter who added an XT1 and several lenses over the past 2 years. My latest addition is the Fujinon 100-400 and the 1.4 extender and I’d thought others might find it helpful to hear of my experience and thoughts. Received the lens and extender last week and had the opportunity to put it through it’s paces this past weekend. I should note that I have experience with long lenses as I currently own the Canon 300mmf4L (non-IS) and 400f5.6L along with both the Canon 1.4 and 2x extenders. In the past I also owned Canon’s first version of their 100-400 but did not shoot with it often as I was never pleased with the AF speed or IQ. I do shoot wildlife in Florida (mostly shore birds) and birds in flight (BIF) along with airshows, bike races and trains. I’ve always been drawn to long lenses as I like to extract subjects and compress distances and I appreciate the subject isolation that can be achieved with long glass and proper technique…………..
