Amazon.com Product Description
Tamron's high-power 18-250mm zoom lens is a photographer's dream come true. While conventional 35mm film cameras typically require two lenses to cover 28-388mm, the Tamron 18-250mm lens does it in one, with a 13.9x zoom level delivering enormous photographic freedom in a single compact housing. The life of a digital photographer has never been better. Despite achieving the ultra telephoto capabilities of a 388mm lens (35mm equivalent), this Tamron zoom lens sports an extremely compact optical system. Unlike previous Tamron lenses, the lens optimizes the power distribution of the entire optical configuration without using XR glass, letting you achieve both ultra-high-power magnification and a minimal size. In addition to offering low dispersion (LD) glass to eliminate chromatic aberration and sharpen ultra-long shots, the lens offers such special materials as hybrid aspherical elements and anomalous dispersion (AD) glass to achieve three goals at once: increased magnification, compact size, and improved image quality. Macro Photos and Fighting Glare
The Tamron 18-250mm is great for macro photos, too, with a maximum magnification ratio of 1:3.5 letting you fill the frame with a subject approximately the size of a business card. As a result, you can easily and conveniently enjoy close-up (macro) photography of flowers, insects, and more. Tamron has also adopted various countermeasures against ghosting and flare, common problems in digital photography. The lens employs internal surface coating and new multilayer coating technology to minimize reflections that occur when light enters through the front element, while also reducing image-degrading effects caused by the imagers themselves. - Lens construction: 13 groups and 16 elements

 All-in-one zoom lens. January 24, 2010
caldwin (Nashville, TN USA)
I have a Canon Rebel XTi digital camera and also a Sony DSC-H7
with a 15X optical zoom. For travel pictures I have always used
the Sony because it didn't require all the extra lenses. This
Tamron lens gives me the zoom range I need (14X) with the Canon
without having to take along a lot of other lenses.

Is this a good lens? Yes. Is it right for you? It depends.
If you plan to do a fair amount of *outdoor* travel and want to zoom without swapping lenses, this lens is probably right for you. Why?
- This lens is much lighter than lenses with VR/OS (vibration reduction/optical zoom). If most of your shooting is outdoors, then you probably need a light lens more than you need VR/OS.
- The photo quality is good when zooming, as long as you have enough light to use a high shutter speed.
- I've found the focus to be relatively fast and quiet, which is nice when you are taking photos on the go.
- This lens is really dropping in price, so you'll save some bucks while still getting a good quality lens.
If you plan to shoot indoors or want to take the best pictures possible, this is probably not the best lens for you. Why?
- If you are traveling and want to take pictures indoors, consider going for a lens with an f stop of 1.8 or lower or at least getting a lens with VR/OS. The f stop only goes down 3.5 on this lens, and gets higher when you start to zoom.
- If you want to take the best picture possible and you are traveling and don't care about the weight, get a lens with VR/OS. This will help take clear picture when you zoom or are dealing with overcast.
- If you are not traveling and have all the time in the world, why not get a nice 50-200 zoom and just swap it in as necessary. You can get one that is a better quality and cheeper than this lens.
Hope that helps!
Great Lens, Super Convenient, A Little Slow November 23, 2009
D. Patterson (Northfield, MN United States)
I love this lens, it was a Christmas gift last year. My only complaint is that my batteries SEEM to drain a little faster with it, and it focuses and takes photos a little slower than the original 18-55 lens. I also have a 75-300 lens. This lens is the best for general use, since I never have to switch anything or carry anything extra. I am not a professional, just an amateur that takes thousands of photos a year. With two little kids in tow, the convenience and versatility of this lens cannot be beat!
Some trade-offs, but overall a good all-in-one lens October 2, 2009

In the 18-55mm range, I find that this lens mostly performs like the Canon EF-S 18-55mm that came with my Digital Rebel kit. It definitely has compromises, though, which were necessary to get the 13.8x zoom range into a single lens. The Tamron 18-250mm vignettes generally on f/4 and wider when you're at the wide angle end of the zoom range. The vignetting can be compensated for in Photoshop, but it becomes worse when a filter is attached. I have to be really careful if I use a polarizer to keep the aperture narrower than f/4. The sharpness at the far end of the telephoto range isn't the best, either. This article goes into that in some detail, comparing it to a Canon professional telephoto lens:
[...]
Generally, they're comparable at the center of the image, but the Tamron sharpness falls off significantly toward the corners when used at the telephoto end of the zoom range. This matches my observations.
As with all non-stabilized telephoto lenses, you really need a fast shutter speed to overcome camera shake at the far end of the telephoto range. I find that 1/320s or faster is generally adequate with this lens, but due to the narrow aperture requirement (f/6.3) at 250mm, it means that you really need a lot of light to take an effective telephoto shot at ISO 100. Since I take mostly landscapes, that's not normally an issue. If I were more into wildlife or people photography, however, it definitely would be.
[...]
I compared it specifically with this review of the EF-S 18-55 to convince myself that I wouldn't be losing any quality or functionality at the wide angle end of the zoom:
[...]
I'm not sure if I agree with their vignetting tests, though. I personally think the vignetting is worse with the Tamron.
All in all, the Tamron 18-250mm lens is a good travel lens and is an excellent choice for the back country, where weight is a major issue but a 3x zoom just won't capture everything you want. It takes great shots up to about the 150mm range and OK shots beyond this (tripod strongly recommended for 200mm and above.) I've taken great candid portraits and wildlife photos with it, although neither is really this lens' strength. In general, it's not going to give you the same results as a professional lens, but for those who need to travel light, it would be hard to find a better lens for the same weight.
LOVE IT! LOVE IT! LOVE IT! September 10, 2009
Another Shopper (San Diego, CA)
I am so happy with this lens. It is everything I need all in one handy little package. Great for everyday shots at 18mm, then extends to fabulous zoom capability at 250 mm. It is only slightly less a lens than my Canon 300mm, but so much easier to have on my camera.
Images are sharp, crisp and clear. I don't know when I'll need to get another lens!
