I have used this lens for about two months now. Focus speed is lightning fast and accurate and the L glass is perfection. It's a little heavy for a walk around lens (I use the 17-85 mm for that) but it is always in my bag. You won't be disappointed.

I believe I got mine in 2006 or 2007 and it has never disappointed. The f4 works for most outdoor use and it is a lens you can carry easily compared to the 2.8 with foot. The amazing quality really showed when I used it with my now retired film body, but also shows when my 17-85 is at telephoto and...

Amazing image quality and image stabilization

No weaknesses; Nicking it on price would not be fair because the big white Canon lenses are top tier and it seems like they spare nothing to make them

Like many of Canon's L-series (luxury) lenses, this one is finished in cream or off-white, rather than the usual black. The idea is that the outer surface reflects more light, and therefore incurs less heat build-up when used in bright sunlight for long periods of time.

Sharpness across the zoom range; weather sealing; autofocus speed

Good but not great for chromatic aberration

Part of Canon's professional L-series, the Canon EF 70-200mm f/4L IS USM boasts in-built image stabilisation. It's the IS in the name that distinguishes the Canon EF 70-200mm f/4L IS USM from the cheaper 70-200mm f/4L USM.

I am very pleased with this lens, I have used it a lot since I got it and very happy with the results of the photographs I have taken.

I have been the 70-200/4 L IS since it was introduced in 2007 and this is my second one after the previous one was given to a relative as a Christmas gift. The pictures from both units are consistently sharp indoors or outside and the constant f/4 aperture makes it easy to satisfy clients and family...

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

Easy to use. Great glass, motor very quiet, solid body and is an awfully lot better Thant Canon 70/3 lens ! Also, looks great on my Canon 700D.

The compact RF 70-200mm with f4 and image stabilizer is an expensive but razor-sharp zoom for Canon full-frame cameras.

Small and light, very sharp at all focal lengths, fast autofocus and excellent image stabilization, Weatherproof.

Expensive, can not use stand mount or teleconverter.

I bought this lens back in 2011, I still have it and it's as good as new - in pristine condition, functioning perfectly and it is in many ways my best lens. The things I like about are: Image-Stabilization - this lens benefits from excellent IS - it makes the lens more versatile, more useful and...

Oh man! This lens is some fun! Easy to use. Pictures are beautifully clear & brings you right into the action. Fast & quiet. Love this lens.
