This is the sharpest lens I have ever owned, not just from Canon but also compared to other prime lenses from Pentax, Nikon, and Fuji. It focuses fast too but that's expected of a wide angle lens. It fits perfectly when you cradle the camera in your left hand unlike many flimsy zoom lenses that feel like there are a million small plastic parts about to break at any moment. The image stabilization works well, keeps you out of trouble down to about 1/8 second, very handy for indoor shots or after sunset shots.

So far this is the best lens I have owned to date. Super crisp. Love that I can get shots indoors in tighter spaces than with my 50mm. Love!

Does exactly what I need it to and does it fast. I love having a wide-angle lens and with this one, I won't need another.

I have had this lens about a year. It has not received the recognition it deserves. It is sharp and has IS. I use on both a full frame (5d III) and on crop body (7d II and SL1). On a SL 1 it's about as minimalist as you can get. A truly great street lens which produces high quality images. I take the SL1 / 28 mm combo hiking and have produced some of my favorite images. A good travel lens. Always in my bag.

I love this lens, especially for the money. I'm an intermediate level, and now have several L lenses in my pack. Don't be deterred this is not an L series. It's a steal piece of glass at this price point. It's quiet, IS is very effective, AF fairly quick. There is good reason this lens has a constant 5 star rating. You will be very happy with the performance of this lens, guaranteed. I love it.

I use this lens most of the time on my Canon 7D Mark II (before that on my 7D) and I love it for its size. It is the perfect walk around lens. The lens is sharp, even wide open and therefore its fast enough in low light conditions.

I got this lens to use with my glidecam and I am very pleased with the purchase. Not too wide of an angle, no distortion at the edges. Just right.

I bought this lens to use with a Sony a7R II and a Canon 5D Mark III. It works great for both cameras! It's especially nice to use with the Sony mirrorless on a gimbal.

Realizing that most DSLR are big and heavy, I decided not to upgrade, but put together a small, light and fun camera. The end results was a Canon SL1, EF 28mm F2.8 IS lens and 270 Flash. Great pictures and video, and fun to use and carry around.

Great for all around photography. I have a Canon that has a 1.6 crop factor, and this lens therefore acts like a 35mm f2.8. The IS is great to have, especially for video, and I would highly recommend for photo-journalistic style shooting.
