AF 70-300mm f/4.0-5.6 Di LD Macro Zoom Lens Features
Low Dispersion (LD) Glass for Greater Lens Sharpness
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 low dispersion 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.)"

Like the older LD design, the new lens has a close-up mode (not strictly "macro") position that allows images 1/2 lifesize on the negative. That's about twice the size of most 300mm zooms lacking this feature.
Compared to the Canon lenses, it includes a lens hood ($$ from Canon) and a six year USA warranty (vs. 1 year). It's a bit noiser than the Canon lenses in autofocusing. Additionally, the Canon 75-300 III is a considerably older design, which came out well before the needs of digital cameras were known. One slight drawback is that the Tamron uses 62mm filters vs. 58mm for the Canon (which is the same size as the popular 18-55 kit lens).
Comparing this lens to it's competition - the Nikon 70-300 & Sigma 70-300:
The 3 lenses are comparable in length (4.6"), diameter (3"), & weight (1#). They each have 9 bladed apertures. They are all about the same price. None have VR - you have to spend 400 more bucks to get this for a Nikon.
The Sigma and Tamron are superior to the Nikon, because
- they have LD glass,
- they are Digital Integrated,
- they have focus motors,
- they have Macro modes (1:2),
The Tamron is superior to the Sigma, because
- it is a newer design (introduced 1/08 as opposed to 10/03),
- it has a 6 year Warranty, as opposed to only a 1yr for the Sigma.
Notes: The Tamron and Nikon use 62mm filters, the Sigma uses 58mm.

- The lens has practically zero aberration, which is a great surprise (I admit I expected it for the bucks). I tried taking sample pictures in high contrast outdoor environments - the contours are just fine!
- What is kind of shocking is its sharpness, even the images taken at 300 mm without a tripod came out sharp.
- The lens is BIG.
- The motor is a little noisy and slow - switch to manual focus if you mind.
On the whole, a very good product.
I was originally leery of purchasing a 3rd party lens (this was my first), but figured I'd give this a try since I knew a couple other people with this lens who liked it, plus I had read some not-so-good reviews about the Canon equivalent.
This lens is much sharper than my Canon 28-135 IS lens which cost twice as much used on that big auction site. I'm about to replace that with Tamron's 28-75 f/2.8 lens based upon my favorable experience with this lens.
The lens comes with a hood too, which was a nice touch, one that Canon does not provide with their consumer-level lenses.
