Summary: Excellent lens when paired with my A99. Fast focusing and tracking, and it's built very well. Not very happy with Adorama, though. The lens was dirty and grimy when I got it and they didn't disclose how much wear and tear it had when they listed it. Also, they're slow to ship.
Summary: I have used this lens for a year now, fairly constantly. It takes a while to get used to it. It does not especially like low light and it is not weather proof. It would make a very good south-west lens, but in the east you have to be aware of these issues.
Summary: i got this lens for an african safari trip. it's way big and heavy for carrying in your hands for hours at a time. but those are the only downsides. as i started taking pics of wild animals, i was happy that i bought this lens.
Summary: Although this is not a prime lens, it has image quality rivaling primes in all it's focal length. Simply the best zoom lens in this focal range compared to competitors. Wish it had weather sealing. Very good companion to my A900.
Summary: I have just upgraded from the 70300G to this lens and it produces some stunning results matched with in my case the A77! I think the 70300G though is a lot better buy unless you need the extra which I found I do for birds etc? If you want the best Sony have at the moment you won't be disapointed!
Summary: Hallo. Über das Objektiv gibt es absolut nichts zu meckern! Super Qualität und Abbildungsleistung. Von der Sonnenblende kann man das nicht sagen. Meine hat 3 Wochen gehalten, dann ist sie gebrochen.
