This is a great bundle. The lens is amazing, it covers majority of my shooting needs and has become my primary lens. Good speed, good quality. I also really like the bundle that came with it. Some of the items I didn’t think I would use, but like them very much. There are lot of different options to protect the lens and keep it clean. I highly recommend the lens and bundle.

I've had this lens for about 4 years, almost as long as I've owned my 6D. It is simply a great, versatile lens with no major flaws. As I have been riding in this journey of photography and learning all the ins and outs, I've always enjoyed trying to find those unique shots only a wide angle gives you. Now, using my M50 for Zoom, on a Viltrox Speed Booster, I use this lens for a fantastic webcam combo. I've been using this lens to vlog a bit, as well. Even though the M50 is a small mirrorless, it is still well balanced since this lens is so light.

Chose this lens due to filter size: 77mm. All of my lenses excluding 100mm macro use 77mm filters, thus eliminating purchase of additional filters.

Great glass I love using it , only reason 4 stars is because it’s a f/4 so not great in low light

Bought this to take Real Estate photos. I have the canon 35mm 1.8 And canon 24-70mm 2.8 & prefer this lens over those two for real estate. However, for family sessions I use the 35mm and for studio newborn I use the 24-70mm

Great value! I’ve purchased this for real estate gigs and I’ve been using it for so many things. It doesn’t have image stabilization but I’m using adapted to a Sony body so that doesn’t affect me. It does have soft corners but at the price point and flexibility of this lens I feel it is an awesome value. Oh and this works great on the MC-11 adapted to a Sony body, the auto focus works just fine for photos only. No auto focus for video when adapted to Sony cameras.

I went back and fore on f4 vs F2.8. In the end, it was about the most likely use-cases I encounter. For me, with the decent ISO and noise management of the 5D III, this lens made the most sense. Certainly the 'Value to IQ ratio' is a no-brainer. I have plenty of scenic images made with this lens now - and I'm delighted. I may have difficulty composing at this end of the wide angle range - but that's not the lens's problem. It really sharp (even wide open) - even at the edges and corners. I thought the IS was unnecessary on this type of lens. Surely, I'd be using a tripod mostly ? Hmm, not necessarily - it's become a favorite walkabout choice. More interesting than the midrange zoom. Don't think about it - value, quality and utility. BTW - it's plastic. But it is solid and feels like a quality build. I'm not gentle with gear and it's holding up well.

I originally looked at the 16-35mm f2.8 for large group photos and landscape work. But realized I didn't need the extra stops because the DOF is too narrow at 2.8 anyway, so for 1/3 the price this is a good compromise. Working great so far!

Great choice for a walkaround lens
By PhilUKNet
There is a lot of choice if you want a general Canon walkaround zoom. However, if you have a crop body camera then the EF 24-70mm F2.8L and EF 24-105mm F4L aren't all that wide. At the consumer level there is the EF-S 17-85mm F4-5.6 or EF-S 18-55mm F3.5-5.6. These focal lengths are useful but the lenses aren't L quality and they are a little slow.For crop bodies, the EF-S 17-55mm F2.8 IS is a fast lens with Image Stabilisation but it is a little expensive and not quite built to L standards...

A great lens at any money
By tc.boxer
They often call this lens an "entry level" "L" lens. What you must understnd is, that's because it doesn't cost ($) or more, like the rest of them.This lens produces sharp, contrasty photos, with frantastic color, from 17mm right through 40mm, And at f/4. Most lens have a sweet spot, I've owned many f/1.4s and f/2.8 lens that were so soft you had to stop them down just to get a sharp photo. This lens is great at f/4 and just gets better. Fast and quiet focus, just perfectFor a lot of people...
