Tamron AF 17-50mm F/2.8 XR Di-II LD SP ZL Aspherical Zoom Lens for Canon Digital SLR Cameras

Product page says that an accessory lens hood was included with purchase. Shipment came in a timely manner but I found no lens hood in the box. I’m too lazy to return so I said f**&k it.

Sharp and fast lens but drop it once and it will break. I dropped my and the plastic shattered. I have dropped my Olympus lenses that are also made of plastic more than once but they have never shattered. The only damage is a couple of dents. Impact damage is not covered under Tamron warranty so now I’m out of a very expensive lens. Oh it’s also very loud.

Wide open performance is oK. The build quality sucks, or should I say, is on par with the same mid-level junk that most companies are feeding us these days. Comparable build to the nikon 18-70. ( I like my wide tokina better but it’s af noise is almost unusable in some situations.) On the tamron, without being mishandled or dropped the filter ring really loose after 3 months of use. It doesn’t appear that it can be tightend down with the screws easily either. Also severe dust problems with back element after 4 months. If you’re a pro or can afford it go with the nikon 17-55. You always get what you pay for and I think this is my last 3rd party lens.
