If you are considering this lens as an upgrade, do it sooner rather than later. If you are thinking that it's too expensive, and a lessser lens will work 'just as well' you are wrong.

This lens takes razor sharp pictures in every situation; Low light, sports, portraits, and anything else; I had been using the 75-300 IS F/4.5-5.6 Canon lens, but was having difficulty with school gyms and their low light; This lens blows it out of the water!

This lens is heavy; And expensive; But the quality is unmatched, and the images it produces are outstanding

The Canon EF 70-200mm F2.8L IS USM II is a spectacular lens that is significantly better than its predecessor and yields excellent results.

Superior optical quality; 4-Stop Image Stabilization; Tank-Like Build Quality

Switches can be accidentally switched; New kids on the block

Perhaps the most versatile of all moderate tele zoom focal lengths, the 70-200mm or thereabouts range is a hallmark and standard-bearer for many optical companies. Being a constant aperture (fast) zoom, this lens opens up numerous focusing, depth of field and perhaps as important low light shooting...

I sold my f/2 135L and my 70-200 2.8L IS (I) to buy this lens. Absolutely no regrets. The 135 was an amazing lens, but without IS, I was just not always willing to shoot with it under about 1/100 due to camera shake.

fantastic images throughout the range and apertures

Just not a good walk-around lens due to size

A year ago Canon unveiled an upgraded version of one of its crown jewels: the 70–200mm f/2.8L IS lens. The original, debuting nearly 10 years ago as one of the first f/2.8 lenses with IS, was fast, plus sharp at the wider focal lengths. It was heavy, though, and at $1,700 (street), expensive.

Gary Wolstenholme reviews the latest incarnation of Canon's 70-200mm f/2.8 lens.

Excellent weather sealed build; Lightening quick focusing; Effective four stop stabiliser; Very sharp at all apertures and focal lengths

Price may be beyond some people's budget; Falloff of illumination towards the corners at 200mm

Excellent lens to the Canon lineup and I must say one of the sharpest lenses I've ever had the opportunity to use period. The new formula Canon has used for this lens makes the images very sharp and the image crops are amazing to look at.

Superb image quality (crops are still amazingly clear); very fast AF; IS is as advertised and better than the Mark I

Hefty piece of glass...some may have difficulty the jump in price from the Mark I

The Canon EF 70-200mm f/2.8L IS II USM is a member of Canon's flagship L-series of lenses. This lens is tough and built for the rigours of professional use, featuring dust and water-resistance. Four-stop image stabilisation is available with two modes for static and moving subjects.

Bought this product after much research.. was planning to get the earlier version of this but then when this one came I was hooked on to its clarity.. a must buy for any serious photographer.. thought a bit heavy, its performance is the best in the lot..

I had the version 1 of this lens that after a calibration from Canon it was one of the best lenses I had. Initially I was sceptical about this new one but still gave in and bought the Mk 2 version. I am not a pixel peeper but the difference is very obvious.

Very high resolution
