[Canon EF 70-300mm IS USM] Top image quality at a Great Price
From Tobias
Have the past two months, the Canon EF 70-300 4-5,6 IS USM. Use it with my EOS 50D. Through the crop factor of 1.6 of the APS-C sensor (for any 2, 3 and 4-digit EOS models) If you have a 112-480mm lens, so a super-telephoto zoom.
When unpacking the first shock “: The thing weighs about 600g. But that is exactly why this lens, I personally find it brilliant. By weight, it is possible the camera with the lens a lot calmer in the hands than with lightweights” . Furthermore, it is immediately noticed a very good workmanship. Nothing wobbles or rattle. No game. Everything is very soft and without a jerk move. A lock function prevents accidental 70mm “moving the lens. The metal bayonet completes the processing is very good.
Some people say The aperture value is not the best. That may be. But due to the extremely well-functioning IS (image stabilizer), it is also possible with a freehand shots shutter speed of 1 / 60 seconds to make, without a loss of sharpness to recognize. So make the worse aperture compensated. The IS is from the 3rd Owned generation and 2 modes. A mode similar to both horizontal and vertical movements. The 2nd Mode is similar to the horizontal movements. Ideal for Mitschwenken a moving object (eg car) on a tripod. The Ultrasonic Motor (USM) is always very quiet and very precise. Even with freehand shots and a focal length of 300mm (ie 480mm for APS-C sensors) are super-sharp images. The picture quality is top. When my camera no distortion and no vignetting visible. This could be caused by various programs (The Canon Professional Program) be removed. The colors and the contrast is just fed up.
In various forums, this lens as a hidden L lens “announced. To eat it, too. I had the 70-300 4-5,6 direct with the 70-200 4 L IS without compare. The image quality was not much better . The longer 100mm focal length, the 50Euro less, and of course by the IS much the decision on the 70-300mm.
There is a shortcoming in this lens is. The IS works great, but it is clear to hear. For me, this is uninteresting. The camera makes when pressing the shutter noise louder 
I would always choose for this lens. This agrees with the price / performance ratio. Who to 100mm focal length can do more and too much “money, should the 20-200mm 4 L IS USM for more than double buy.
