Last week I recieved a new toy to enjoy some picture sessions: A Canon EF 70-300mm f4-5.6 IS USM lens. I'm so pleased with it!
Following my picture inpirations, I enjoy to much the perfectly smooth and soft blur is can produce. So much stronger to much deep that the one produce by my Canon EF-S 18-55mm f/3.5-5.6 IS Lens!
Second crazy amazing feature, the USM motor used for the autofocus. So accurate and so fast! However, one issue is the desperate need of lights of this lens which evolved some trouble to focalize in such condion. I have also notice some trouble to focalize when lighting is really to strong (like taking a picture of the sun).
This lens is stabilize with two different modes: The first mode is the classic full stabilization mode for none moving subject. The second mode is a vertical or horitonal stabilization which allow to move the camera when taking a picture of a moving subject for example. It's a really nice feature for wildlife or sport pictures.
I'm really happy with this lens with is also perfect for my macro picture with 300mm lens techniques. It needs to take pictures at 2 meters from the subject but the blur is so nice and the picture quite shape for such lens.
