Reviews of Canon EF 100-400mm f4.5-5.6L IS USM Lens*

EF 100-400mm is VersatileI bought the lens for wild bird photography. I considered the EF 400 5.6, but I thought I better go with IS. I am a pure amateur hobbyist. I like the portability of the lens. The great close focus (5.9′) has been useful in getting images of flowers and insects. Most of my use is at the 400mm, but I like the ability to shorten-up if the subject comes closer. I use it mostly from a monopod, and I am still working to get consistently sharp images of moving birds. I have seen the work of professionals who use the same lens, so I know what is possible with my Canon equipment.The EF 100-400mm is heavy! For me, the push-pull zoom feature is an interesting challenge – keep it too loose, and it creeps longer; too tight, and you miss a shot trying to shorten it. I’ll keep working with it to see if I can give it 5 Stars.

A Great ValueThis is my second purchase of this lens (the first got stolen) so that right there should tell you how much I like this lens. My favorite subject for this lens is Airshows but is a great Nature lens except in the darkest of conditions.

Great Lens, Know the LimitsI purchased this lens as I needed to give myself a bit more reach than my 70-200 could offer, even with the 1.4 extender. The versatility with the lens is great. The 100-400 range is perfect for photographing airplanes, wildlife, sports, etc. The images are sharp up until about 300mm and then there is a slight drop off in sharpness as you go beyond 300. The focusing at times can be a bit slow, which can be tough if you are trying to lock in on a moving subject. Finally the lens does seem to vignette a lot when mounted to a full frame, which is to be somewhat expected but maybe not so much to the degree I get at times. The lens is push/pull which is a bit uncommon now. However, the adjustment period really isn’t bad and after a day of playing around it feels normal. The tension ring is great for allowing you to determine how much or how little force will be required to zoom in or out.

I have had this lens for nearly 5 months now and it does seem to be what I utilize the most. I still use my 70-200 f4L IS at times when I know I will not need that extra reach. My 70-200 copy is amazingly sharp and I find it to be a bit faster at focusing.
Overall, I do recommend this lens to almost everyone. It is a great versatile lens but does have a few limitations. It will be interesting to see if Canon does come up with something to replace it in the coming years as the current version is coming up on 16 years already. My version was a 2013 build, based on both the serial number and having come with the new center pinch lens cap. The design might be old, but Canon is still actively making them!
