Prior to owning this lens I did not realise it was possible for a lens to create sharp clear images at every aperture and zoom length. I chose this non IS version even though I could afford the IS version. Why? Because I use this lens primarily for shooting birds, animals and fast moving children.

Superior build quality; Super-sharp images; Fast auto-focus

This was my second L glass and I love it. Though my EF 24-70 f/2.8 lens does a really good job as an all-purpose lens, I always missed the reach of a tele zoom (for street & portrait photos). I almost put my trigger on the EF 70-200 f/4 L because of its high reputation and its attractive price.

F2.8; sharp even at wide open; great contrast and color

Not weather-sealed; Rotation between the lens and the camera (EOS 30d

Don't worry that it's not the mark II of this lens. Even without the image stabilization, this is easily the best lens I've ever had the pleasure in owning. I picked up this lens to take sports photographs for my old high school in the beginning of the 2017-18 school year.

I didn't know what to expect with this lens after reading the reviews. I am happy with its performance and quality. I have used it handheld with excellent results and performance. Anyone looking for a lens that does it all will love this lens.

wildlife; architecture; weddings

Not much to say other than It's an awesome lens. I use it for family portraits and for the kids sports events. Crisp clear pictures in low lights. It's my favorite lens.

It's great for portraits as well as sports events..

A bit heavy

This is my favorite lens for several reasons. It's my first 'Image Stabilization' lens and I wonder

Sharp, Fast, L glass, good build; Great all around pro lens

Big price jump compared to non-IS version

Superb build quality, sharp as a tack images, could not be happier, and with a Sony A7 ii and IBIS (In-Body Image Stabilization) who needs the Canon IS version That IS version is almost double the price of this one, which I got on sale for $599. Another B & H home run ! :)

This is such a pleasure to use and I am so happy I bought it. Coupled with my 5D I am finally getting the results I have sought for so many years. It is heavy but what quality and performance. I wanted the IS version but could not afford the extra price.

Tremendous brokeh and sharpness; Focusing has been effortless and the feel of the lens is pure luxury

None just a little heavy and takes some getting used to

Yes, I would recommend this to a friend

Fast / accurate auto-focus

I use this for wildlife, sports and weddings. An amazing lens which I'm very glad I purchased. If your thinking about it get it. You won't be disappointed. I was really impressed with deliver and service from WEX.

Consistent Output; Durable; Quick Focus; Sharp Focus; Strong Construction
