Canon EF 100-400mm f/4.5-5.6L IS II Teardown – Is this the best Lens ever build?

Is this the best lens ever built?” wonders Lensrental’s Roger Cicala while tearing apart Canon’s new EF 100-400mm f/4.5-5.6L IS II lens.

R. Cicala writes:

I know I can’t really, without showing you dozens of other lenses, do a good job of impressing you with just how robustly engineered this lens is. I will say that the insides look more like what we’d expect to see in a 500mm f/4 or 600mm f/4 lens, rather than a telezoom. It’s by far the most heavily engineered zoom lens [we] have ever seen; and we’ve seen the insides of dozens of lenses in this range.

Well done, Canon engineers, well done!

The whole disassembling process is documented with lots of images – very interesting to see how this lens is build internally, and to read Cicala’s comments about how well Canon engineered this lens.
