Canon's EF 28-300mm lens gives me a versatile, high quality, professional lens for my outdoor photography. Image quality is excellent and I couldn't resist the discounted price.

Versatility and image quality

Heavy; but the versatility is worth it

The 28-300mm has so many functions. I've had this lens for almost 2 years with no regrets. I travel throughout the Columbia Gorge and have captured amazing outdoor shots. It isn't the lightest lens but the range is so exceptional you can get away with taking the one lens.

So far so good. I am enjoying the lens as a single travel lens. However the salesman did not tell me I was getting a grey market product. I do think that should be revealed before purchasing.

Great lens. Bought to cover all other lenses, in other words, we do not have to swap lenses now. It is a bit heavy, and needs to be rested on something to take good clear pictures. Ideally it would be better if it was lighter. Ideal for a male to use, but a bit heavy (unless you are a weightlifter!

This is a wonderful lens. It has just one drawback, and that is its weight. I wish it were lighter, but I've got plenty of arm and back strength, so it's doable. It takes beautiful pictures over a wide zoom range, so it is now my everyday lens.

it is a versatile Lens , good if you travel , so you can cover a wide focal , instead of carrying different lenses. It is scary to people that you want to snap shot them. A little Heavy , but doesn't bother me at all. It feels like a Tank . and makes you proud.

"This L series lens is exactly what the travel photographer wants. Mostly. It's a perfect focal length range for a full frame camera body, it is very sharp and despite and extended focal length range does not exhibit significant barrel or pincushion distortion.

The Canon EF 28-300mm f/3.5-5.6L IS USM ($2,689) is a bit of an oddity when compared with other modern lenses. Its push-pull design requires you to handle it like a trombone to zoom, and its high-end build quality (and price) are rare for an all-in-one zoom lens.

10.7x zoom range; Full-frame compatibility; Reasonably sharp through most of its range; Includes lens hood and tripod collar

Expensive; Noticeable distortion; Soft edges; Push-pull zoom design; Some color fringing

I've had this lens for a year now and I use it nearly every weekend for taking pictures of youth soccer games. The lens focuses very quickly compared to my old Canon 70-300mm and the pictures come out very sharp.

I am using this lens on a 5D3. First the focusing is an issue since the camera is having problems it does not have with any of the other (5) L lenses I use. The ISO is also kicked into really high numbers in indoor shots and for no appreciable reason, resulting in very noisy shots.
