Summary: I bought this lens to make it easier for the wife to get pics at our kids sporting events, I do not know the outcome of indoor shots yet,i was drawn in by the 18/270 range, I have several lenses that cover these ranges but decided to get the all inclusive and see what happens, my wife loves the idea that one lens covers the whole indoor volleyball situation without changing lenses, so far at the house all pics have been very good, tough to compare to a 135mm f2.0 lens...
Pros: Easily Interchangeable, Fast / accurate auto-focus, Rugged, Strong Construction
Excerpt: As an all-around lens, this product offers very good sharpness and minimum aberations. the motor seems quieter than the 18-250 version and the weight about the same. I lkie the extra reach at the maximum zoom for flower closeups.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Summary: I really like this lens. It's what's on my camera by default. I no longer use my kit 18-55 or 70-300 telephoto. I do, however, still lean heavily on the fixed 50 f1.8 (a very nice lens, by the way). So... the pros and cons and inbetweens: 1. WTF... it's the same price as the Nikon and Canon, but those lenses have vibration compensation (not needed in a sony lens, since VC is done by the camera body). So why isn't it cheaper??? 2. It's not so good at acquiring focus.
Summary: I used this lens majority of the time for sport action purpose with my Sony A77. The lens worked well with the single frame shot drive. However, the performance is slightly degraded with continuous drive mode. Pictures blurringness is very obvious. Otherwise, this would be a great all in one lens to carry to all event.
Excerpt: Purchased this lens to extend my lens selection as I use a Sony 5R Nex System. I also had to purchase an adapter which has extended my lenses to include any Sony A-Mount systems.<br /><br />I am very pleased with the lens. The range is ideal for a "take one" lens approach and I have been quite impressed with the sharpness of the images.
Pros: Consistent Output, Easily Interchangeable, Lightweight, Nice Bokeh, Strong Construction
Summary: This is a nice walk around lens for when you want a lot of different zoom options but don't want to carry a lot of gear. It is not super sturdy, though. Sadly, about a month after I got it, I dropped it. It was damaged. I can still use it, but the outsides of the images lose some of the crispness, which is very disappointing. I hadn't been able to use it long enough before the damage, though, to really evaluate it's quality well.
