Summary: From my uses this lens is as good as the kit zoom, but with an 11.1 zoom ratio versus the kit's 3.1. I use it on an NEX-6 and is seems to focus more reliably than the Sony. IOW, I've had trouble with the Sony failing to focus, whereas while the Tamron 18-200 might take a small moment longer, it is more reliable. There is a zoom lock that prevents the lens from extending (zooming out) while hanging downward on your neck strap.
Summary: Wow! this lens is wonderful. Pictures are really sharp. Normally, these all-in-one lenses are not used at night, however, I tried it and the pictures I got at night are stunning. It is really worth the investment.
Excerpt: Travel and family photography.<br /><br />1.The shutter does not work correctly every time, remains open over 30 sec.<br />2.When starting the camera it say´s sometimes "unknown lens" and it is not possible to take any photos.<br />3.Sometimes the camera (Sony Nex 7) is totally dead. <br /><br />When changing the kit lens, sony 18-55mm, the camera, however, works ok.
Pros: Durable, Lightweight, Strong Construction
Cons: Compability Wit Nex 7, The Automatic Exposure
Excerpt: I am not an expert photographer by any means; I know just enough to get by. I recently returned from a vacation trip to the Grand Canyon and although I took several other lenses, I found myself using this one pretty much exclusively. The convenience of the zoom means everything when you want to photograph everything!
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus
Excerpt: Things that are great: one lens, many focal lengths. Less great, the longer focal lengths are not as good as the shorter ones. I was hoping to use it to shoot some events. It is only so-so at the longer lengths. I bought this to go with my NEX-7. This set is to be a lightweight sub for my big DSLR and lens.
Pros: Easily Interchangeable, Lightweight, Nice Bokeh, One Lens Does Most
Excerpt: I bought this as a travel lens. I hate changing lenses when on vacation. I have used several Tamron lenses in the past and they have been great. Quality control is good and I have never been disappointed. I currently use two Tamron lenses on my Nikon D700 and this lens has similar high quality. Autofocus at 200 mm is not ery fast but I think that is a function of the Sony autofocus system not the lens.
Excerpt: This Tamron Lens is an excellent alternative to Sony's example.<br /> It is a beautiful lens and is a perfect match to the Black NEX7, It produces good sharp contrasting images through zoom ratios.<br />The internal focusing mechanism without the body ring turning is good feature <br /><br />I am very happy with my purchase from B&H
Pros: Consistent Output, Durable, Easily Interchangeable, Lightweight, Strong Construction
Excerpt: Super super nice - do not get a NEX body with a kit the 18-55 mm lens - get this lens. It is slightly longer than the kit lens retractet and it is not that heavy - it is slightly narrower then the Sony silver 70-200 so it suits the body better - it is also in black - it is a nicer lens then the black Sony 70-200 e-mount which is even more money.I compared all 3 lenses - it was a toss between the older silver Sony and the Tamron as far as speed and quality and use - but...
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Nice Bokeh, Rugged, Strong Construction
