This is the second lens for my Canon EOS 40D. Because I cannot afford the Canon L-series lens and I really need the range to complement my Canon EF 18-55mm f/3.5-5.6 IS kit lens, I bought a used one from a nice guy who posted the ads on ClubSNAP Photography Forum. It cost only SGD 700, compared with the new one around SGD 1000-1100 on various shop in Singapore or IDR 5,998,400 on JPCKemang - Indonesia. The best thing from this lens is the Image Stabilizer (IS). I tried to take a shot at 300mm range, and from the viewfinder of my 40D, I saw the shake compensated. I found the IS works very effectively. I haven't done some tests for image quality, sharpness, auto focusing, and other things, but before I decided to buy this lens, I read many reviews that recommend this lens as the telephoto zoom lens after the expensive white 70-200 L series.Specifications
