I replaced two Canon lenses (18-135 and 70-300) with this single lens and I'm glad I did it. Most of my pictures are hand-held, on hikes or vacation, and I really don't want to carry a bunch of lenses or change them in the field. In the last year, I've been hiking on a glacier in Canada and crossing the Sahara on horseback. Neither is a great place to change lenses and there were too many times I missed a shot I wanted because the right lens was in the bag, not on the camera.
This one is small, light, easy to use. I see no color or shape distortion. I can get the same results handheld at slower shutter speeds using Tamron's VC as I got with Canon's IS.
I do have a few small gotcha's, though. One is that the direction of the twist to zoom in is opposite direction to the Canon lens. That took a bit of getting used to. Another is that auto focusing is a little louder. That might be a problem for places where silence is important. Third (and last), there is very little twist difference between 200mm and 300mm focal lengths. In other words, it is difficult to make precise choices at the upper ends of the range. (All zooms are more granular at their lower numbers; it is just that with a range this wide it is more pronounced than usual.)
All in all, I'm very happy with this lens and recommend it to you.

I have owned and tested the Tamron 28-300mm VC zoom lens for about 2 months now. Here is an early review from my experience so far.
Pros:
Excellent optical quality (stronger at shorter focal length)
Versatile multi-purpose walk around lens. Leave this one on your camera and no need to lug around extra lenses.
Amazing focal length range 28-300 equals to 44-480 on 1.6x crop sensor.
Compact size and light weight.
Vibration compensation works very well zoomed out and in macro shots
Solid and well built quality
Rubberize grip feels much better then most Canon lenses
Reasonable price relative to comparable lenses
Included hood
Center-pinch lens cap should be an industry standard.
Extra peace of mind with standard 6 year manufacturer warranty
Cons:
Wider angle would be nice on a 1.6x crop sensor. If you shoot a lot of landscapes 44mm may not be enough.
In low light, indoor conditions, the f3.5-6.3 aperture means I have to increase the ISO and use longer shutter speeds to shoot brighter.
Occasionally, the AF searches a bit in low light shooting
Not a big deal but, the lens creeps (extends with gravity) when lens lock is off and the lens is pointing down.
In conclusion, the Tamron AF 28-300mm VC lens is an exceptional choice if you are looking for a general walk around lens to keep on your camera. You can not beat the optical performance with such range from a relatively compact, light and well-built package, especially considering the price.

I love this lens -- an all-purpose carry-around lens with VC built in, and very good optics. I am surprised consistently by the IQ of the photos I am taking - not what I expected from a general walk-around lens of this type.
With my previous Nikon kit -- the 18-200 was one of my favorite lenses, but the IQ was always a bit worse than what I got with any of my dedicated lenses...
Now with my Canon kit, I can clearly state that the Tamron 28-300 VC lens consistently gives me far better shots that the Nikon 18-200 ever did in the same lighting situations. The added zoom is a blessing and basically allows you to take your Canon camera, this lens, and nothing else on most photo shoots, especially when traveling.
I highly recommend this lens as an all-purpose walk-around lens, and I think you will find that the IQ is stunning -- beyond what you would imagine with a lens of this type.
My only wish -- that it was 18-300 because you DO miss the wider angle from 18-28 at times...but at this price point and this quality, I can't recommend it more. You will not be sorry with this lens, and you might, like myself, find yourself basically using this for almost all situations. It hasn't come off my Canon 40D in the two months I have had both.

I have a Canon 1DMkII, 1Ds and a 40D. I also have the Canon lenses - 28-300mm L IS, 100-400mm L IS, 70-200mm L IS and 300mm L IS The lenses and cameras are great needless to say. However they are big, heavy (except for the 40D) and not great to carry around all day when spending the day taking photos of something when you are not looking for that ultimate quality.
The Tamron fits that need perfectly. Remember I am comparing it to the best that Canon makes so being second is not a bad thing! Combined with the 40D or a Canon XTi it makes a perfect walk around combination. You can go from wide angle to telephoto with one lens. The resolution is fine and the image stabilization performs nicely and is especially noticeable at the 300mm range.
The price is good and the build quality is good. I wouldn't buy any other lens of this type. There are reviews in Popular Photo magazine and on their web site.

I have been using this lens for about a month and I am very satisfied with it. The sharpness of the photographs is more than adequate for my needs and the VC works great. I routinely take photographs down to 1/8 which come out very sharp. When I need a flexible lens that will rapidly switch between wide angle and telephoto, this is the one I use.
Pros -
1. Huge range. I find my photographs are reasonably sharp at all focal lenths.
2. The VC works fantastic and truly allows you to capture photographs at much slower shutter speeds.
3. The build feels very solid.
4. Your options for a lens in this range are very limited. For the price and functionality I feel this is a very good lens.
5. The macro functionality works very well. It is not as good as a dedicated macro lens, but again, it is very nice to have the feature in an all-in-one lens.
Cons -
1. Without flash, this is not a practical indoors lens if your subjects are moving. For stationary objects the VC makes this an acceptable indoor lens.
2. The autofocus is not fast enough for photographing sports or other quick moving subjects.
3. There is a catch when zooming around 250mm. When the lens is at 300mm and you zoom back, the lens encounters resistence around 250mm and feels like it is stuck. At first I thought there was something wrong, but I have decided it is just a quirk that I need to get used to.
I gave four stars because it is has some minor drawbacks, most of which I knew before I purchased it. To get five stars the next version needs to autofocus faster. Constant f/2.8 would be nice also, but you can't expect that in a lens covering this range at this price. In fact, there is no lens on the market covering this range that has constant f/2.8.
