Excerpt: Almost as good as the Canon, has image stabilization, 5 year warranty... half the price. What's not to like? Lightroom does a great job fixing any barrel distortion and vignetting. I gave it 4 stars because I had to send a copy back due to the IS causing blur. But Tamron fixed it very quickly and with no fuss.
Pros: Consistent Output, Fast / accurate auto-focus, Nice Bokeh
Excerpt: I've had quite a lot of different lenses, from 24-70L to Tamron 28-75, 24-105L, e.t.c. Tamron 24-70mm VC doesn't disappoint. It builds on the success of the 28-75mm but adds a little bit of sharpness in addition to VC. Focusing is pretty fast, just like the Canon's L-version. The lens is very sharp in the center. One thing to keep in mind is vignetting.
Pros: Consistent Output, Durable, Fast / accurate auto-focus, Nice Bokeh, Strong Construction
Summary: The lens itself is great, love the sharpness of the lens.. Takes great photos. Amazon should state on there that it really does not carry the Tamron warranty of 6 years. You can not register this product and then I also was not eligible for the rebate.
Summary: The seller I purchased this lens from was DavisMAX. Apparently Tamron does not acknowledge lenses sold from this seller. Tried to register the lens online and got an error message to "call Tamron". I was told by the person I spoke with that while this is technically a "real" Tamron lens, made in the same factory as the rest, this seller is not authorized to sell them in the US. Tamron will not touch it for service, and there is NO warranty available.
Summary: I have been looking at the reviews for this lens for a couple of months while I mustered up the courage to purchase it. I then took the next step of renting both the Canon OEM model and the Tamron. Hands down the VC function makes this the clear overall winner. I tested it out under several conditions and I was able to have clear shots that took my pictures up to the next level.
Love the lense! Hate that Amazon screwed me on the rebate.

Summary: First off, I LOVE the lens. I got this as an upgrade to my 28-75 when I upgraded to a Full Frame Canon 6D. This is my current go-to lens and stays on the camera 80% of the time. The problem, when I bought the lens it had a notice that it would come with a 4% rebate after 35 days that would turn into a credit. After about 40 days, I email Amazon Customer support and asked about the rebate. The response I got was "What rebate? I don't see any.
Excerpt: I love the lens. I am using it on a crop sensor, however, and hope to soon go full frame as it isn't wide enough for me on crop sensor. This lens was shipped very quickly and had no problems with the transaction!
