The Canon EF 28-105mm standard zoom lens retains the optical capability of Canon's previous EF 28-105mm USM lens but with a refined exterior design. The lens is distinguished by a ring-type ultra-sonic monitor (USM) drive that provides silent, high-speed autofocusing, along with full-time manual focusing. The 1.6-foot close-focusing distance, meanwhile, lets you take great close-up portraits and nature shots. A good match for the Canon EOS A2/A2e or ELAN 7 series cameras with built-in flashes, the EF 28-105mm lens is an excellent zoom lens for everyday use. The lens carries a one-year warranty.

I needed to replace the lens on my Canon Rebel XT D-SLR. The EF-S on first glance seemed like the perfect replacement since Canon produced the EF-S series specifically for the compressed sensor D-SLR line. After weighing the pros and cons of the two, I chose this EF lens largely on the basis of price. It was the right choice, and I haven't found any loss of features or quality.
Multiplying the range by 1.6 for a 35mm equivalence (if you have a Rebel XT, 20D or 30D), this model is really just a slightly wide angle to stronger telephoto zoom. (about 45mm-170mm if it was a 35mm film camera) If this range suits you, then this lens is an excellent value over a EF-S wide-angle/telephoto zoom. You'll keep all of the features, save money and have a faster lens.
The EF series meshes well with the current line of Canon digital SLRs. In addition, unlike the EF-S series, they are compatible with all of the Canon EOS products including higher-end cameras like the Mark II.
SPECIFIC OBSERVATIONS FROM WEEKS OF USE:
My first concern before purchasing this lens was the MINIMUM FOCUS DISTANCE of 0.5 meters, or approximately 18 inches. I do a lot of macro work transferring images into digital, so I was a tad worried. However, after getting the lens and zooming in, I realized that the focusing distance wasn't really an issue after all. In most cases, I could manage to stand six or so inches further away and still get a highly magnified shot. So that you can see that the macro function works well, I've uploaded an image of a small hamster photographed at 102mm.
My second concern was lens QUALITY AND SHARPNESS, particularly in the wide-angle setting near the edges of the photo.
