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

Item just as described. Very good value for money. Item well packed to ensure no damage during delivery.

Excellent for mid range photography. Annoying noise on autofocus reflecting in video mode.

faster ; quick focus .Excellent for mid range photography

jerking noise on focus and while video capture

This lens is exactly what I was expecting. The quality of the photos is excellent. The IS works as advertised. I highly reccomend it. If you can't afford Canon's L glass, try this one. It's light and compact, and makes a perfect walk-around lens.

The Canon 70-300mm zoom lens is a good lens. It works as it's advertised to. Canon quality can't be beat. It's light enough so you don't get tired carrying it around all day. I highly recommend it.

I have used this lens extensively over the past several years with 5D2 and 5D3 bodies. I am always amazed of the speed to focus and the beautiful image quality. It is a class act and fully lives up to it "L" pedigree. The only very minor negative is its weight which is slightly heavy.

excellent image quality; fast focus on a 5D3; built like a tank

slightly heavy

Updated from my 55-250, the quality of the pictures from this lens is so much better, highly reccomend.

Bought this lens to go on a Canon Eos 200D DSLR Camera. It is fast to focus and has a good zoom range (maybe not as far as others). The photos come out crisp and clear. Even though the lens does feel heavy, when you have it attached to your camera I didn't really notice it.

Purchased 70-300L for use on my 7D for daylight field sports, and most importantly, to carry while when traveling. Processed (in Lightroom & NIK Suite) images from the 7D + 70-300L compare very favorably with those from my 5D MkII + 70-200L MkII.

Compact; Light weight; Fast auto focus (with both full and panning modes); Full time manual focus; Very sharp images; Responds well to micro focus adjustment

Cost, but then again it has 'L' build quality and performance; Lens collar is both expensive and (currently) unavailable

Pin point focussing; Am in Costa Rica at the moment and couldn't be more pleased

Can't find anything bad to say
