I Got this lens back in Dec. and wanted to use it a lot before leaving a review. I own this one and the canon version and honestly This is a better deal for the fact the construction of it is better. The canon version is made of cheap plastic and doesn't hold well for the active or abusive photographer,it's great if you're just a hobbyist photographer and you like the peace of mind of an IS lens. The Tamron lens has been through a lot of punishment and hasn't broke yet  (including being dropped, not recommending you drop it though.). The telephoto zoom works great ( I got great detail of the super moon back a few months ago, I was shocked at the amount of detail of the moons craters I got.) Sports, wild life and portraits come out great, though if your reliant on the image stabalizing lenses than this takes time to get used to. I have used this lens on a canon Mark II 5d and also on a canon T1i. the out come is the same for a full size sensor and c-size. Just note that on the c(smaller)sensor you tend to get a little dark fringing. Auto focus is a bit loud but fast, and works well on a 2x telephoto extender.....

I planned to get this lens for a long time after getting my hands on the amazing and to this date my best Canon lens ever 135mm f/2. I along the way thought whether to get something more versatile and with a zoom capacity up to 300mm but my obsession with the primes made me want this one and I am glad I did. So sharp, not heavy and great sharp images. I recently used this one on a trip to Kenya with no tripod to catch some lion activity and trust me - i did not disappoint me. You can check some photos here at www.burcubasar.com - with the price, zoom range, the sharpness that comes with a prime lens - one of the best Canon lenses out there.

Excellent addition to the Canon Lens lineup.
Being fairly new to photography, I wanted a cheap telephoto to help me get the hang of using a telephoto to compose shots and the Canon EF-S 55-250mm f/4.0-5.6 IS does the trick.
It is priced very very reasonably and is very easy to use. You are not going to be able to take fast action shots with auto focus on but for the hobbyist who has a little bit more time to set up a shot, this does the trick perfectly.
This lens was well used in Alaska, especially useful when taking closer up shots of eagles and whales. Eagles remained high on their tree perches so photos easy to take.
Whales on a moving boat was trickier but still managed to get a few good shots.
Overall am very pleased with this lens. It suits my needs perfectly for the time being. Barring professionals (hence they have the "L"-woooo series which costs many times more than this) this will suit the majority of people's need.

Solid 4 star rating great lens for the price. It is not as sturdy as other Canon lenses, but works very good. The price may lead you to believe that this lens is cheap, however, do more research and you'll see its an awesome little investment. Great beginner lens.

Recieved a great price on a new lens through Amazon. Lens was packaged and shipped safe and secure by Amazon. Lens takes some great photos, everything I expected from Canon. Image stabilizer is a great feature for clear photographs. I would recommend this product.

Not a lot I can say about this lens other than it is typical Canon in that it does what it is supposed to. You get more than what you pay for with this lens because of the auto focus feature. Not all telephoto lenses are equal especially not equal to a Canon. I highly recommend this lens.

This Tamron is a great lens!  I've replaced my previous walk-around lens with this lens.  My previous walk-around lens was the Canon 28-135mm f/3.5-5.6.  The Tamron can create sharp photos, has VC, and can get good images in low light.

Pros:
- VC (Tamron's version of Image Stabilization)
- Sharp images, without having to stop down
- Low light capability

Cons:
- Focus is not quite as fast as my Canon lenses with USM
- Focus is more noisy than my Canon lenses with USM
- Zoom ring work in opposite direction as all my other Canon lenses (I just need to get used to this)

I'm very pleased with this lens given the price. Although it won't give a Canon L lens a run for its money, it's reasonable fast and has a nice range. The build quality is very good for this price point. Both the zoom movement and focusing are smooth. The zoom marking are well-marked. While the mount is plastic rather than metal, this keeps the lens weight down, which is always something that I appreciate. Despite being plastic the mount and housing are more than sturdy enough for even the most avid amateur photographer.

The image stabilization works very well and is an essential feature to have unless you have rock-steady hands.

I find the image quality to be excellent at all zoom ranges except for when it's at its max range, but even then it's more than acceptable.

It's certainly not the best lens that Canon makes, but I don't think there's another zoom out there that can match this performance at this price. It's a great second lens if you have a crop sensor body (such as the Rebel series) and the 18-55mm zoom (which is a common kit lens). The pair provides a wide range of shooting opportunities at a very reasonable cost. Highly recommend.

I enjoy using this lens on my Canon cameras. It greatly extends my range of capabilities. I carry it every where.

This lens is compact, well-built and versatile for everyday use. It's hardly left my SL1 since I bought it last month. The auto-focus is fast, quiet and sharp. Manual focus is a bit trickier but still works well.

Compared to the 50mm f/1.8 lens that I most frequently use, this lens is wider but is better for close-up shots. I can easily focus on subjects inches away that would be a serious challenge with the 50mm.

Canon seriously should consider making this the default kit lens for the Rebel line, especially for the SL1. I have no qualms about leaving my other lenses at home anymore.

Excellent quality glass lens for its price. Should be the first choice for any amateur thats uses Canon cameras and wants to get a good telephoto zoom lens. It is close in price for 70-300 mm with IS. But you will get so much better quality image with this lens that you forget the IS. Besides you can get a nice Monopod for 50 bucks, which i highly recommend to use in telephoto lenses.

If you are about to get serious in photography you won't regreat buying this lens

This little lens is so much fun!  Now it's non coupled so the camera does not read the aperture info, also does not auto focus.  Focusing is almost an non issue though. Basically I leave it just short of infinity for most situations, only set it closer when doing close work.  The lens seems to be very well made, especially considering the price.  Also seems to be sharp, no complains there.  It's a specialized lens for sure but truly a fun addition to my lens lineup.

This is a great lens to add to your collection. I own the D40 which comes with the 18-55mm lens, and found that it was insufficient to capture all of the photos that I needed to take. What I have quickly figured out (and liked) about this lens is that the VR function does more than just steady a highly zoomed shot. I figured out that I can use this function in dimly lit situations, like night shooting or indoor shooting with out a flash and the VR will virtually eliminate any motion blur that you would normally experience from a longer shutter speed.  Plus, you can't beat this price! Phenomenal lens for the price.

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 paid $400. for my fish eye lens for my Canon Rebel SLR.  For a nominal price, you can have FUN, interesting photos. Really fun set. Have not played enough with the wide angle. Overall, Excellent. Feedback to AUKEY, There is not 1 word of instruction included with your lenses. I figured it out. Each lens screws on to the clip which goes over camera eye. That aside, I still think this is a good deal, works well and comes with a nice small carrying case. Worth the price.
