This lens replaced the Kit-telephoto zoom Canon. The quality is no comparison, this is really Objetktiv knackscharf in all focal areas. On my Canon 550D and even more on the 50D actually nothing to be desired - vivid colors, no reflexes (Kaiser Hood in use), no vignetting - the cameras have correction data! for this Objetktiv. I use in daylight for Tierfotos like Aperture 6.3 and ISO 640, the shutter speeds are nice and short. And the animals knackscharf even at 100% magnification. Each coat hair or feather are accurately counting. Tip. In the tree shade works. Autofocus quickly and quietly beautiful, I've never had to intervene by hand. The stabilizer ensures that I can take pictures from his hand long, which is almost a must in constantly moving animals. When panning not forget provide stability at level 2. With tripod just too slow, this is then used in the twilight, and then slowly come the limits of luminous intensity to light. Who wants more, must pick up the L Lens with Aperture 2.8 and to spend a fortune for it - not everyone can.
Beautifully also the locking of the zoom, which prevents that simply extends it while wearing. Can quickly be on and off with your fingernail.
Weight still pleasant, stability, easy processing top. So is traveling always with the backpack.
