A fantastic lens. Everything you would expect from a L series lens. I have now taken around 3,000 photos using this lens on a 500D, mainly of kids playing sport. The focal length range is ideal. The build quality is great, it is as good today as when it came out of the box. Solid construction.

Easy to use; Build quality

Awesome piece of glass! A bit heavy and bummer that it did not come with a tripod collar.

Great quality; nice glass; nice range

Heavy; no tripod collar

The Canon EF 70-300mm f/4-5.6 USM L IS delivers high quality results throughout the zoom range but especially at 70mm. At 300mm it is clearly better than its in-house cousins (EF 70-300mm f/4-5.6 USM IS & EF 70-300mm f/4.5-5.6 USM DO IS) reaching very good to excellent center results combined very...

Just came back from the Chesapeake Bay area where I used this lens almost exclusively. (together with the canon5 Marklll The focus is fast, sharp as a tack, and never failed me. What impressed me the most is how true the colors remained even of the farthest objects.

I was looking for a lens that could take shots of wildlife from a distance. This lens certainly fits the bill and the IS helps in low light. I was also looking at the 100-400mm lens but the negative comments about its barrel focusing system pushed me towards this one.

Consistent Output; Durable; Easily Interchangeable; Fast / accurate auto-focus; Rugged; Strong Construction

Heavy; Poor in Low Light

I haven't had this lens long but have found it to be excellent. It is quite expensive so I gave it 4 stars for value. This is not a reflection of the quality but just the price. I did receive the money back from Canon quite fast this time in contrast to my previous experience.

Canon's lens range is already extensive and includes two 70-300mm models: the f/4-5.6 IS USM and f/4.5-5.6 DO IS USM optics. The new Canon EF 70-300mm f/4-5.6L IS USM is one of the company's professional L-series models, in traditional off-white with the distinctive red ring around the front.

Excellent image quality in a compact size. Image stabilization works very well. The downside is the F stop of 4-5.6 and the weight if you plan to...

Size and quality

F stop of 4-5.6

I've used the product to photograph landscape and some wildlife. The Canon 70-300L works very well on both my Canon 5D2 and my Canon 50D. the only problem is that you can't zoom with the lens shade reversed.

Quaility product; Fast focusing

Too expensive; Heavy

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.
