I am very pleased with this lens.I'm not a professional, just someone who enjoys taking photos and using Photoshop Elements/Premiere to do some creative things for digital photo albums, etc.

Fair Pricequality Lens

I have been using DLSRs for quite some time and moved to full-frame camera a while ago. Having used many lenses from every stable including Canon, Nikon, Sigma, Tamron, Tokina & Samyang and almost every focal length (right from 10mm to 400 mm), I must say this lens is easily one of the best...

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

You want a medium telephoto lens for your Canon dSLR, something with a constant aperture, solidly built with pro quality, yet light enough to carry on adventure to some faraway part of the world. You have looked at the f2.8 models but didn't think you could afford them or the Sherpa to carry them.

Professional grade build quality, including dust and moisture sealing; four stops of image stabilization system; relatively lightweight

The tripod collar is optional; relatively expensive

I purchased this lens for my 700D after reading multiple reviews and researching various lenses. This is my first L lens and I am very pleased with the pictures and the way the lens handles.

Fast auto-focus; Great Value; Lightweight; Superior build quality; Super-sharp images

none

I would highly recommend buying the 2.8 version .

Very sharp light weight lens. Wide open bokeh is not bad colours are outstanding. As I mostly use this lens on a Monopod I.S is not a concern but would be nice for hand held. Focus and zoom rings operate very smoothly.

This lens is a blessing to shoot all day as it is half the weight of the f2.8 one and price, you can't go wrong if you one of these in your bag.

I like this lens so much its on my camera 95% of the time

I don't have any problems with this lens

Another great lens from Canon. I have loved this lens very much when using in tripod, unfortunately cannot use those focal lengths without IS.

great IQ and build; lightweight for its category

lack of IS with those focal lengths; but you can get the IS version if this is a concern

This is the lens if you want a classic images at lower cost. My hands are not used to for taking handheld pictures on this lens so I am using tripod. I generally shoot outdoors so never faced slow focus. Clarity of images are really awesome. Love the color composition of end product.

The Canon EF 70-200mm f/4L IS USM ($1,349 direct) isn't as lauded as the company's f/2.8 IS lens with the same zoom range, but it's priced about $650 less, making it an attractive option for shooters who can live with a slower lens.
