Canon EF 70-200 f/2.8L IS II lens review by Justin VanLeeuwen at Canon Rumors: Is it worth more than twice the 70-200 f’/4L IS? Yes, if the ability to shoot at f’/2.8 across this entire range is what you need.

The lens was tested on EOS 5D Mark III, Mark II, and 7D bodies, and according to the reviewer performed admirably on every occasion:

I can’t find anything wrong with the 70-200 f’/2.8 L IS II, even the weight isn’t so significant that I whine, especially when I consider the results. If you want one of the very best telephoto zoom lenses with a consistent wide-open aperture this is, without compromise, it. If you want incredibly professional looking photographs with a sharp subject and a blurred out background with the versatility of a zoom, this is for you. Is it worth more than twice the 70-200 f’/4L IS? Yes, if the ability to shoot at f’/2.8 across this entire range is what you need. If you’re stuck shooting at

1/60th of a second at 200mm, or even 1/120th of a second at 200mm this lens could very much be for you. If you’re a person who makes purchases without compromise, without wanting to know that there’s just something better around the corner, this is for you – this is it – you’re done.

Maybe an exaggeration, we’re never really done. Very little has made me put this lens down, tough I strongly favoured the Canon 200mm f’/2.0 L IS when I was reviewing it, but versus $7,000 the 70-200 comes across as a bargain! If you need a telephoto zoom, this is the one worth saving up for, if you’re less interested in a consistent aperture and more interested in range, check out Craig’s review on the Canon 70-300 f’/4-5.6L IS. Just remember, variable aperture means variable light, which might mess you up when you’re shooting manual and/or with flash.

Unequivocally, the Canon 70-200 f’/2.8 L IS II is the first lens I’d take out with me to guarantee I’d be able to make high quality, professional looking photographs.

Pros

Telephoto zoom is highly useful to cover the focal range vs. equivalent primes
Image stabilization makes shooting hand-held images cleaner in challenging environments
Best in class Auto-focus
Clean and sharp image quality
Quality build for potential bumps and drops

Cons

Most expensive of Canon’s 70-200 series
Heavy, especially over long periods of time
Lens cap is a PITA when the hood is attached (I bought an off-brand pinch cap for $2)
Super obvious white lens = expensive target for thieves/gawkers
