I have used this product for about 3 months now and am very satisfied with it. The sound quality is very good and the well designed interface (similar to iphone) is very ease to learn to use. The only thing I do not like about is the 64 Gig capacity is not big enough for my entire collection. Hopefully next generation will increase capacity to 128 Gig. I am using the unit currently with Itunes 9.03 and Win 7 64 bit and everything works fine.

I bought this lens when i bought my Canon XSi back in May. Its a great “walk around” lens. it covers a huge spectrum of range. For daylight photography and with a flash it works very well. My only real complaint is that its heavy and a little big… but this is expected with the 18 to 200 range.
IS works very well. At the 150 to 200mm range there is a noticeable difference between IS turned on and Off.
pared with the canon 50mm f 1.4 i think i have all the glass i’ll need for a while. now its just a matter of learning how to use it well.

A good value – inconsistent results. If you are looking for something relatively inexpensive and fun to carry around, this is the lens for you. Quality is good in good light, most of the time, and can be exceptional sometimes. The plasticy feel doesn’t bother me because I avoid carrying around a hunk of metal.
The VR works like a charm in good light.
However, I’ve noticed softness (at all apertures, including f/8) often enough where I would not use this lens for any professional work. For example, the Nikkor 180 f/2.8 blows this lens away in quality of manufacture and resulting photos.
I’ve also noticed softness and noise in almost all of my night photos using this lens, even with a very heavy tripod and no wind.
The focusing system on the lens also is slow as molasses. I tried to capture the Blue Angels flying low over the homes in my neighborhood (an awesome annual occurence), and each shot was blown as the lens hunted for focus. Plenty of good light for high shutter speeds (midday, 1/2500s at f/4), but by the time the lens was focused, the subject had moved so far the photo was blown.
If you want to have fun and need a good lens, buy this one. If you are a professional or OBAM (obessessed amateur), save for the higher quality lenses because you’ll be disappointed. Moving subjects, such as sports or action photography, again not your lens.
I wish more people would objectively weigh the positives and the negatives in their reviews so that those considering buying this lens can make an informed decision. While this is a very good lens on a tight budget, this is not a great lens directly compared against other similar (and more expensive) lenses.
