Good value - useful all-in-one lens Aug 09, 2005
By A. C. Sisto
"Educated Amateur"
Like a baseball player with a decent batting average, some power, a little bit of speed and fairly good fielding ability, the Tamron 18-200 lens won't be an All-Star any time soon because it does not excel at any one thing. But, like that $500k/year utility infielder, this lens DOES provide a very good all-around value for what it is. Does it compare to a prime lens at either end? Heck, no. Is it a good lens to use when you can't carry a wide choice of lenses with you? Absolutely.
I've been using this lens on my 20D quite a bit and have only a few minor gripes: it tends to hunt for AF (especially as you get closer to 200mm), and it's not the quietest lens I've used.
An earlier reviewer mentioned that it maxed out at about 160mm. My own analysis shows that it is short of 200mm, but not by that large an extent; I found it much closer to 190. Still, there's no doubt that these zoom lenses with extreme ranges like this have a built-in fudge factor.
Another reviewer described the problems he encountered when using two screw-on filters. There aren't too many primes that I've used that will avoid vignetting when using two filters. Heck, my 10-22 can barely handle one extra-slim. As for darkening the image - well, you're adding two more pieces of glass to a highly-complex lens assembly... just asking for trouble.
As for the concern regarding blur at longer focal lengths, I highly recommend the use of a tripod. I noticed the exact same thing - blur and lack of sharpness - at lengths over 100mm. Keep the old rule of thumb in mind - if you're shooting handheld, your shutter speed should be no slower than the inverse of your focal length. A 200mm lens on a 20D (or Rebel XT for that matter), is an effective 320mm - I wouldn't recommend shooting any slower than 1/500 at max zoom with this lens - UNLESS you're using a tripod. When I mounted it firmly, I got great shots with no blur.
Keep in mind that you get what you pay for here: the convenience of a wide-angle, normal, and moderate telephoto lens in one piece. If you're shooting professionally, or need absolutely perfect images, then carry the three or four lenses that this would otherwise replace in your bag. But if you want one easy-to-use, satisfactory lens, go for this one. It's a jack-of-all-trades, ace-of-none kinda deal.

 Never ceases to amaze Jun 28, 2006
By mcenut
I have owned this lens for over a year now and it never ceases to amaze me when I see the photos it produces. Over this last year I have come to learn a thing or two about how to use this lens.
1) If you are going to shoot indoors, or in low light, with a long focal length (like 200mm) use a tripod or plenty of ambient light. This lens doesn't have a built in image stabilizer so you are going to steady the lens with the tripod or use a real fast shutter speed to minimize your hand jitter.
2) Use a smaller aperture. I have found that my best photos come from an aperture of 8.0 thru 16. These apertures aren't great for bokeh (background blur) but they sure do allow you to take razor sharp pictures.
Praise.
Focal range. With one lens you are able to take nice wide-angle shots (18mm) and with the twist of zoom ring you have a nice telephoto lens (200mm) Definitely a good walk around lens for the day at the botanical gardens, museum or amusement park.
Build quality. This lens gives you a nice solid feel in your hands. Give it a shake and it doesn't make a sound. The zoom and focus rings move smoothly without being sloppy. With a lens this well built you would expect it to be heavy. Not so with this lens, it's quite light (which is something you really appreciate after a long day of carrying it around.)
Minimal chromatic aberrations. The lens' three hybrid aspherical elements and two low dispersion glass elements correct for almost all lateral and on-axis aberrations making most of your images optically clear.
Size. At it's lowest focal length (18mm) the lens is small enough to fit into a mid size top loading camera bag while still attached to the camera body.
Complaint?
Well yes, I do have one minor complaint about the lens. Auto focus is slow. How slow? Well let's just say you won't want to try and photograph a two year old on the move. I have found that I can keep fast moving objects in better focus by switching to manual.

Great all use lens Apr 20, 2005
By S. Mingus
I recently purchased this lens for use on my Canon 20D. I was never happy with the lens that came with the camera. I've been very happy with this lens.
Pros:
- Quality construction. The lens doesn't feel cheap.
- Zoom range of this lens is fantastic.
- Image quality is great.
- Internal focusing makes using filters and hoods a piece of cake
- Zoom lock is nice so the zoom ring doesn't turn while stored or carried.
- Price. For the money this lens will give you a lot of bang for the buck.
Con:
- Auto focusing is a bit slow for a moving subject.

Good image quality, good value, excellent versatility Jan 24, 2007
By William Porter
Before purchasing my Pentax K100D, I had for years used all three models in the Canon Powershot S-series of "superzoom" fixed-lens cameras (S1, S2 and S3). I like my Pentax digital SLR a lot, but after I purchased it (and sold my Canon) I really missed the Canon's versatility. I have recovered most of that versatility with this Tamron 18-200 DiII lens, which is good at the wide angle end, good in the middle and pretty good at telephoto as well (I like to shoot birds) and which even provides some macro capability. This is now my default all-purpose lens. It's not the best choice for low-light shooting, but if the light's decent or you can use a flash, this is a good lens, takes good photos, and is a very good value. To do noticeably better than this, you will have to pay a lot more and probably give up the versatility, too.
I give the lens a rating of 4 stars rather than 5 simply because, by nature, this is a bit of a compromise lens. If you don't need the versatility - if for example you don't really need focal lengths over 70mm - then you can get a lens with slightly superior image quality for the same price or even less (perhaps much less if you buy used). The Pentax 50-200 may be slightly sharper in the telephoto range. My Sigma 28-70 F2.8 is faster in its range (the Tamron's max aperture is 3.5). And while it's fine for my needs, this lens deserves to be called macro only in a generous sense. But as a total package, it's hard to beat.

Good all-around lens for the money May 20, 2009
By Dexter
My Nikon D90 came packaged with this lens and I've found that this lens can really do it for most occasions. It's 18-200mm flexibility allows for a variety of shooting situations without the hassles of swapping out lenses on the fly. It takes sharp, crisp and clear images and is fully compatible with the D90. However I rated only 4 stars simply because of the fact that this lens does not have the VR (Vibration Reduction) feature of Nikkor lenses. To what extent this may or may not be an issue depends on the person shooting the picture but to me, its a convenience I can get by but would be nice if it had it. So, if you are looking for a lens for your Nikon DSLR, check this one out...Great flexibility (18-200mm) for most situations and good value for the money.
