Friend of the site Dustin Abbott has completed a comprehensive review of Canon’s brand new EF 100-400mm f/4.5-5.6L IS II. If you head over to his review, there’s also a full video review if you prefer to watch instead of read.
I’m not finding much to criticize with this lens. It isn’t cheap, but it is a pretty killer optic with a pro grade build quality. It’s expensive ($2199), but no more so than Canon’s 70-200 f/2.8L or 24-70 f/2.8L variants. When compared with the higher end telephotos, however, it is a great bargain. It offers great reach in a compact package that most users should be able to handhold due to its manageable weight and excellent image stabilizer. It has amazing image quality with next to no real shortcomings. I love my Canon 70-300L and have enjoyed my Tamron 150-600 VC, but this lens has left me in a conundrum. I am strongly considering selling both of these lens in exchange for the new Canon EF 100-400mm f/4.5-5.6L IS USM II. I like it that much.
Stock of this lens is extremely scarce and I suggest pre-ordering it as soon as you’re able if you want to be able to have one for the spring.
