Pros
  • Pure quality, fast focus
Cons
  • Heavy to carry around
It's a great choice for animal watching and wildlife photography. The only disadvantage is that it's quite heavy so it's difficult to carry around. It's better to set up a tripod

Pros
  • Best zoom lens for birds in flight because of push - pull zoom
Cons
  • Heavy, push - pull zoom can suck dust inside
I'm owning this lens for about 7 years and still thinking that it is the best lens for birds in flight. That is because of its push-pull zoom. You can find the bird in the air on 100 mm and change the focus lenght to 400 mm immediadely by pushing it forward.

I tried 3 copies of this lens in the shop and found that 2 of them had very bad IQ and were blurry but one copy was brilliantly sharp and gave very good IQ of the photos on my Canon 60D. So I bought this one.

The lens is sharp on 400 mm from 7,1 aperture on my Canon 60D. It is less sharp on 6,3 aperture.

I've read about the sucking dust ability of the push - pull zoom of this lens. But I've got just few specks of dust for 7 years of using it.

Tried it with Canon 7DMk2 and got bad focus and bad IQ. Had the same result on this camera with Tamron 150-600 G2. Probably I have the bad copy of Canon 7DMk2 or just need to adjust the focus for this lens in Canon 7DMk2.

Overal - highly recommended lens if you find a good copy that suits your camera.

Faer Out
I have had the EF 100-400mm f/4.5-5.6L IS II USM for about 3 months. I use it for birds with a 1.4 extender on a Canon 5Div.

This mark II no longer has push-pull.

It's a very good lens, the best zoom I've owned. It's heavy, and I use it on outings for several hours at a time without a tripod or monopod, but I survive. I try to think of it as exercise, but doing this does bother my back sometimes. I usually loop the tripod connector into my belt or a backpack waistclip in order to ease the strain on my neck and back.

It has good balance (I guess "feel"), has good IS, and can be used handheld and still get sharp photos.

I used to use Canon's 70-300, but this is a very noticeable step up and worth the investment in my mind.

But for some of us without a stash of lenses, and moving to Canon mirror less, the question is, EF 100-400? Or RF 100-500. ??
