A detailed review of the Canon EF 70-300mm f/4-5.6 IS USM Lens. This is a very light weight lens, great for backpacking. I often use this lens for wildlife and flowers (on tall trees). So far no issues. Even though it is constructed out of plastic, this is one rugged lens. I have hit this on walls and other objects when it hangs on my neck, and it has been over a year and still working strong! The zoom is great, and I love the bokeh (make sure you watch the photo slideshow at the end).
If you are a beginner or intermediate photographer on a tight budget and want to start with wildlife photography, this is a definitely a must have for your kit. Remember that EF-S mount lenses are not compatible with full frame DSLRs! If you might upgrade, definitely go for a EF mount lens like this one!
