I purchased this lens to complement the 18-55mm lens that came with my Canon 600D. I also purchased the Canon EF 50 mm f/1.8 II Lens
I am a keen amateur photographer who enjoys photographing a wide range of subject; wildlife, landscapes, architecture and also my cat, dog, daughter and wife!
This lens is perfect for most of the above. It provides the reach needed to photograph birds and other wildlife without disturbing them.
Some reviewers report that this lens is soft, I have not seen this myself. Having been using the lens every day for the past 2 weeks all the images I have are sharp with great colours.
The autofocus works quickly and quietly, although like most sub £500 lenses it will hunt for focus in low light conditions.
The image stabilisation is as good as the 18-55mm and enables the lens to be used handheld in less than ideal conditions.
For the price, this lens is a no brainer for beginners/amateurs that need a zoom lens.
Sure, you won't get the performance of something like the Canon EF 70-200mm f/4.0 L USM Lens
but if you are just starting out or even if you've been snapping away for a while and need more reach then for the price it's perfect for what it does.
