Di II
Lenses are designed for exclusive use on digital cameras with smaller-size imagers and inherit all of the benefits of our Di products. These lenses are not designed for conventional cameras and digital cameras with image sensors larger than 24mm x 16mm.

Extra Refractive Index Glass (XR)
Tamron AF18-200mm F/3.5-6.3 XR Di II at Amazon.com
Special glass for better performance and more compact lens designs
Extra Refractive Index (XR) glass can bend light rays at steeper angles, thereby decreasing the physical length of the lens while enhancing imaging performance by minimizing optical aberrations. This has allowed Tamron to develop a line of shorter, smaller-diameter, lighter lenses without sacrificing lens speed, and actually upgrading image quality compared to older designs. XR glass is costlier than conventional glass but it yields enhanced optical power distribution, making possible many of the outstanding and innovative lens designs that bear the XR designation. XR glass, with its superior light-bending power, makes it possible to design a short-barrel lens with the same light-gathering ability (aperture value) as a long-barrel lens—even with a smaller lens diameter. By using this principle Tamron has been able to shorten the length of the entire optical system and produce lighter, more compact lenses of the same speed, and also to provide greater zoom ranges in lenses that are much more convenient to carry by hand.

Low Dispersion (LD)
Low dispersion (LD) glass elements in a lens help reduce chromatic aberration; the tendency of light of different colors to come to different points of focus at the image plane. Chromatic aberration reduces the sharpness of an image, but glass with an extremely lowdispersion index, has less of a tendency to separate (defract) a ray of light into a rainbow of colors. This characteristic allows the lens designer to effectively compensate for chromatic aberration at the center of the field (on axis), a particular problem at long focal lengths (the telephoto end of the zoom range), and for lateral chromatic aberration (towards the edges of the field) that often occurs at short focal lengths (the wide-angle end of the zoom range.)

Low Dispersion (LD) Glass for Greater Lens Sharpness

Internal Focus (IF)
Internal focusing (IF) provides numerous practical benefits to photographers including a non-rotating front filter ring that facilitates the positioning of polarizing and graduated filters, and more predictable handling because the lens length does not change during focusing. Even more important, Tamron’s Internal Focusing (IF) system provides a much closer minimum focusing distance (MFD) throughout its entire focusing range. In addition, IF improves optical performance by minimizing illumination loss at the corners of the image field, and helps to suppress other aberrations that become more troublesome at different focusing positions.

Zoom Lock
Another original Tamron mechanical engineering concept is the Zoom Lock (ZL), a simple convenience feature that prevents undesired extension of the lens barrel when carrying the camera/lens unit on a neck strap.

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.

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.

By no means am I living on a stack of money so price was very important when buying an all in one lens. Performance was as important as quality and both weighed against price. Each had to be weighted equally. As the Nikon 18-200mm VR cost as much as the D5000 camera itself placed it out of the question. Let's face it, a great deal is $700 for the 18-200mm Nikon. With the Nikon out, the Tamron and Sigma were the only choices but so many choices in these 2 manufacturers lines. Living in the real world I wanted the VC ( Vibration Control) or OS (Optical Stabilization)but knew a monopod would do as well and I like $30 to $40 versus $100 to $120. The Sigma version was very impressive but at a slightly higher price.

Well, the Tamron won! In particular, the Tamron 18-200mm F/3.5-6.3 AF DI-II LD Lens f/ Nikon w/ Built-in motor, 6-Yr US Warranty. When I saw the $100 rebate offer there was no thinking, just ordering. Most of the New York City dealers utilize free shipping and no tax as marketing tools and it works! As I was going to a Car Show on Saturday I decided to have overnight shipping. The lens arrived at 10 am on Friday(thanks UPS!) and was on my camera in 5 minutes. The lens was $189 after rebate!

This lens will never leave my camera! Walking around the car show I got many different shots from standing in one place. The lens performed very well. Soon I was in the habit of having the lens focus twice and it was worth the extra thought. Later that night when I went through the photos, I could not believe I took the photos. Crisp and clear with varying angles due to the flexibility in zoom. The wide angle end was exceptional in taking engine shots. Wall to wall engine and sparkling clear.
