I'm very shocked at how much I liked the Sony 200-600mm f5. 6-6. 3 G OSS after playing with it for a weekend a few weeks ago. I'm not at all saying that because I doubt Sony's ability to make a great lens, but because I found the lightweight, focal length range, relatively compact size, and image stabilization combined well together to create what could arguably be Sony's most useful lens to date for photojournalism.
Though it's only of the G moniker and not a G Master, there is little holding me back in saying that any photographer would be unwise to not purchase this lens. At a $2,000 price point, every photographer will get a number of useful focal lengths along with image stabilization and small size. Plus, it's got a solid image quality! Though despite all of this, I'm still a bit wary as the last time I used a G series lens, I had a bad experience with its build quality. . thephoblographer.com
