[Plastic] It actually took month and a day, from my pre-order with B&H to receiving the lens. With the few dollars I had left, I set up a little informal lens test, (taped dollar bills and stamps on a card) to see just how the lens would perform it terms of sharpness, color, bokeh. And when panning on and off the card, how fast could the lens refocus back to the card? (fast enough for me.) Used different f stops and distances during the test,- camera set to aperture priority. In every case I am delighted to report the lens performed stunningly. Have also hiked around the woods grabbing shots, and again I am very pleased with the results. I know its not inexpensive lens but I am not regretting this purchase.

[Zoom Gear] I love this lens. An added plus is connecting a 2X Teleconverter to it. This lens is a must have.

[0.445 lb] Minimal use as just obtained 1 week ago. A few test images suggests to be extremely well corrected and very very sharp on my Sony A7RII. Have not used with the extender however.

[Plastic] The hype is real - I love this lens! I prefer the manual focus to the auto as, once you get accustomed to, it is much faster. It is a bit pricey but in my opinion worth it.

[Zoom Gear] I bought this lens for A7 before my last trip. With F2.8, I was able to take great pictures of birds and views in the middle range, especially when the light was relatively dim. That is exactly what I am looking for. At the same time, this lens provides a great sharpness to the pictures. The drawbacks are the size and weight. It is not a to-go lens. Also, 70-200mm means that this lens might not be as convenient as a 24-70 or 28-70 in a close quarter shooting (i.e. shooting in a hiking trail or on a street). It is relatively expensive as an Alpha lens. But it worths it.

[0.445 lb] Exceeds my wildest dreams. I have shot all the best lenses, this one tops them all.

[Zoom Gear] My favorite Sony lens this far!

[0.445 lb] I LOVE this lens. I have owned both the EF70-200mm f/2.8L II as well as the VR2 version of the 70-200mm f/2.8 in Nikon. The new GMaster has raised the bar as far as I'm concerned, especially when shooting portraits with the EYE AF mode. It's difficult to get an eye out of focus even wide open and working in close to my subjects. The integral tripod foot is similar to Nikon's and is a superior to the Canon in removal with it's quick release. The lens is SHARP! Tons of contrast and really nice neutral color rendition will allow me to use this for both stills as well as video projects. Sony knocked this one out of the park...

[Plastic] Everything you would expect. Big, fairly heavy - sharp and contrasty at all apertures. Fairly quick AF. The best choice if you need a large, fixed aperture and are willing to pay the price!

[0.445 lb] I have never owned a 70-200 lens, & had a bit of a void in my lens distances. I'm glad I waited for this to come. I'm still getting to know it's nuances, but very happy so far.
