Steve Huff isn't a zoom guy, so the fact that he admits to wanting the new FE 70-200mm f/2.8 GM speaks volumes about the quality of the new lens. In his review, Huff writes:
"During my use with this lens [with an α7R II] I was secretly wishing that I had $2600 laying around with nothing to do as I wanted to buy this lens. I wanted it badly. Not because I need it, or would use it every day but because I have a thing for quality glass and cameras. I know one day I will wish I had this lens for a trip, vacation, specific shoot I am doing or just to have an amazing 70-200 on hand. If I were indeed a zoom guy, I would have ordered this one months ago when it was first made available. It’s a no brainer to anyone who loves this focal range and are looking for a top tier 70-200 f/2.8 lens. Sony’s GM line is stunning, all of them. The 24-70, the 85 1.4 (a drool worthy lens) and now this 70-200 f/2.8. OMG, I just realized that all three of these would offer up the best of all worlds.
"As for this 70-200 GM, it is the finest 70-200 I have ever shot with from build, feel, IQ, color, image stabilization, contrast, pop/depth, etc. There is no question to this lens' quality. Shoot it in the desert heat, shoot it in the Seattle rain. It will deliver the goods."
