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

Now that this lens is older no one has posted for a while. I had the lens but sold it in September 2017 because I found I liked my 70-200 f2.8 better and it was difficult to carry both. However there are times (especially with birds) that my 70-200 is not long enough, even with the 1.4 extender. So I just purchased the 100-400 ii again using the current $400 instant rebate. Here is a test shot from my first outing with it this morning. This is with the 1.4x iii extender. Image is cropped a little but otherwise unadjusted JPEG from 5D4.

There are 100s of recent bird images taken with the 100-400mm II on the Bird Portraits thread, with and without the 1.4xTC.

Elegant trogon taken yesterday at Madera Canyon (Arizona) with 100-400ii and 1.4xiii extender (plus a little cropping and other adjustments in post). A local visitor guide is requesting trogon photos so I went with this setup since I needed the length. However this is likely my last photo shoot with Canon. I received Nikon D850 a week ago (with Nikkor 24-70 and 70-200 2.8 plus extender). I am on the waiting list for the 500 f/5.6PF lens, so after I trade in my Canon gear I will be without a really long lens until it comes in. The Canon 100-400 is great when it works, but I continue to have focus issues in certain situations which is why I sold my first one a couple years ago.

The 100-400mm II is arguably the best longer-range telephoto zoom available. We have taken many 10s of 1000s of bird photos with each of our ones without any focus problems. Nikon’s 80-400mm is an apology of a lens, and some serious Nikon bird shooters use Sonys + Sony 100-400mm when they need a zoom. Goodbye and good luck with your Nikon gear!
