This is definitely a high quality lens, not as slow as it says on paper, image quality maintains high even at max zoom with lots of details. Unless you are shooting high speed events, I see no need for L lenses, this will work for me just fine, I mean, more than just fine!

It's just a joy to use, and very sharp. It's also a significant step up from the Tamron 70-300 VC, you'll have no worries shooting wide open at 300mm with this one! Perfect on APS-C. Also, do not underestimate how important portability is, it's very compact at 70mm.

Sharp throughout zoom range at f5.6, colour and contrast fantastic; Auto focus is amazingly fast, IS is superb; Very compact, not overly heavy; Metal filter threads; Zoom lock means hood can be stored in reverse orientation and still removed without zooming the lens out

None, well, maybe price; The relatively slow aperture and extension on zooming are not cons, in lens terms they are necessary design compromises to make it the size, weight and focal length range it is

This lens is highly versatile and rarely requires me to change lenses. It is a genuine Canon lens with the packaging you would expect to receive if buying the same product in Australia.

I love this lens. The bokeh is nice and the zoom distance is great. My only issue is that when zoomed all the way max the focus is not as sharp as I would like.

I have used and using this lens for some time now and it is probably the best lens I have ever used, the image quality the sharpness is excellent, my experience with this lens has been fantastic definitely a must have lens for all canon slr users.

The image shown is of Canon -EF 70-300mm f/4-5.6L lens and not Canon -EF 70-300mm f/4-5.6 so don't be confused like i was when i received the lens.Its a bit heavy using a tripod would b good and the lens becomes useless in low-light. Over-all its a good lens for a beginner with a good zoom.

Canon's EF 70-300mm f4-5.6L IS USM brings L quality to this popular zoom range. You get tough build quality, quick and quiet USM autofocusing, full-time manual focusing, effective image stabilisation and great optical quality in a barrel that's comfortably shorter (albeit fatter and heavier) than...

I had bought a Canon Rebel T3i just after Christmas....I took it on my vacation in Jan/13 and was very impressed with the quality of the pics....but I wished I had the EF 70-300mm f/4.0-5.6IS USM telephoto lens for the distance shots that I missed...

This lens has an auto and manual setting for focus adjustments and the adjustments give a good blur effect to the image, very nice lens indeed, very good to have this.

This lens does everything I had hoped. There is a huge difference in this lens compared to the 75-275mm. I love it.
