This is a first class long-range zoom lens that is sure to delight discriminating Sony NEX enthusiasts. The only real downsides are its limited f/6.3 aperture at the longest focal length, and a typical amount of linear distortion and light falloff at the widest-angle settings.

Tamron 18-200mm F/3.5-6.3 Di III VC This high power 11.1x zoom lens, which provides an angle of view equivalent to a 27-300mm lens on a 35mm camera, costs around £550 and sports Vibration Compensation and internal focusing.

Over the last weekend and on past ANZAC Day I have had the pleasure of playing with a couple of Sony's finest - the NEX7 and even better, the NEX FS100. Now the FS100 has already been put through its paces at Auscam, and in fact reviewer Chris Oaten summed it up with "I'm gonna be right up front...

Tamron has packed a very wide zoom range of 18-200mm into a rather sleek body, although this lens does weigh in at a fairly hefty 460g. The 10cm body almost doubles in length when fully zoomed in too, measuring 17.5cm.

Those looking for a convenient lens that covers a wide range of focal lengths for their Sony NEX camera should be pleased with the performance from this Tamron optic. Sharpness levels are good for a lens of this type and with a price set almost £100 less expensive than the Sony equivalent it...

Optics are great, I also have a Canon 28-300L I use on my 5DmkIII, this little Tamron creates as good of results as the L..The Tamron build is okay, its a solid little lens but the zoom ring is a little stiff for me (not dampened like a high end lens) AF and VC is awesome and the size is just about...

I estimate about 10% of the picture on the right and left of the image has very soft focus - meaning blurry. That leaves about 80% of the image is quite good. But not enough for me at this price. Am returning it.The focus is fast enough for stills and landscape.

Bought this from getting a lot of use from the Tamron 18-270 on my DSLRs for many years. When I got the Canon M-5, that lens with the adapter was too big and heavy. This one is a lot lighter, of course, but the lens performance is just as good - maybe better.

This is a very good lens for the price. I cannot compare this to the Canon L lenses out there since I no longer have them but this serves as an alternative lens for travel. You may need to bring along a tripod or monopod along.

I used this lens with my m3 and loved it. It was really spectacular. Unfortunately, when I upgraded to the M5 it won't work at all. If you attach it while the M5 is powered on, it gives you a lens error and turns off. If you attach it, while powered off, the camera won't turn on.
