Don't mean to intrude on a question not asked of me, but I've been around the block on this one. This year I tried out the Sony FE 70-200mm twice and liked it. First time I returned it just because I decided I wasn't quite ready to commit to the lens just yet. Second time because I finally came to the decision to keep a split Canon/Sony kit and prefer for all my lenses to be usable on both systems.
Now I have in the EF 70-200mm f/4L IS USM. From a product design standpoint (the aesthetics of the lens design) the Canon is a turd. And I don't love the sound of the IS either (Sony is quieter). But, optically - the optical performance of the lens - I am elated with it. If the Sony had been this good I would not have been able to let it go.
So, to me the Sony 70-200mm is very good, very adequate. The Canon 70-200mm f/4L IS is superb. In other words, both are deserving Photozone's "Highly Recommended" rating, but the Canon version really sings for me.

I remember that about a year ago or so I said I didn't want to replace my EF 70-200mm F/4L IS USM with the FE 70-200mm F/4 G OSS if I decided to buy an A7II. While there wasn't a direct comparison of both lenses by any of the review websites (as in: both lenses on an A7II), I always had the idea that optically the FE 70-200mm F/4 G OSS was no match for the EF 70-200mm F/4L IS USM. Yet, people here thought that optically there would hardly be a difference.
The EF 70-200mm F/4L IS USM is the only Canon item I simply cannot sell. I think it's awesome. I love its image quality, its weight, its looks. It is also built like a tank. And to be honest I find it prettier than the FE 70-200mm F/4 G OSS. So I don't get why people call it a turd (but hey luckily opinions differ sometimes). The IS motor is clearly audible, but it doesn't bother me at all.

I think we all agree there. Yet another reason to think canon over Sony though.
The only problem is that Canon got stuck in the dinosaur age with their sensors and there's a great lack of innovation. I also hate the fact that the only way to accurately use MF, you need to use the LCD on the back.

the Canon 70-200 F4 IS is not that old, right?
It's from 2006.
