So many people recommended the F2.8 16-35. Gladly I didn't listen and instead bought this lens for the value. Satisfies my needs for UWA, which I use for car shooting, landscaping,architecture. Excellent built quality. For the price, it is a keeper.

This lens is really sharp and feels really solid. Weather sealing is a nice touch too. I would have gotten the 16-35 f2.8 if i could afford it, but i don't regret getting this one a bit. Besides, if you want a lens for landscapes, you won't need something at f2.8 anyway. Save the money and get a fast prime for low light stuff.

Amazing for the price ! Packaging is decent ! I used this for a Sony 28mm f2.8

Low light loss & distortion on my Sigma 17-50mm f2.8 zoom. It was worth not getting an "el cheapo" filter!

I ordered the 52mm filter because the 30mm f1.4 sigma lens for sony e-mount cameras has a 52mm thread but after lens arrived, I couldn't fit it on.But after-service support was pretty helpful in telling me this

Canon EF35mm F1.4L IS II USM(フード逆付け)を装着したBG-E20付きのEOS 5D Mark IVがピッタリ入り、隙間にiPad miniや小物も収納できました。クッションの保護性も高く、価格を考えると質感も満足。余計な装飾がなくシンプルなデザインも好印象です。さすがにEOS-1D Xは入りませんでしたが、お散歩スナップなどに手軽で便利なバッグです。とても良い買い物でした。劣化したら、また買おうと思わせる逸品です。*追加した画像は、SIGMA 105mm F1.4 DG HSM | Art(フード逆付け)を装着したBG-E20付きのEOS 5D Mark IVと、SIGMA 12-24mm F4.5-5.6 EX DG HSMを入れたものです。(2018年8月20日 更新)

It tried this lens after my 16-35/f2.8 was stolen. It's a great value compared to Canon's other L series lenses. If you don't need the extra speed of the 2.8 lens, I highly recommend it. The only possible con I could come up with is that it is very light compared to the 16-35, which could imply something about its durability, but that's pure conjecture, and I can't subtract a star for that. It could simply be that the 16-35 contains more glass to accomplish the 2.8 aperture.

Does what it needs to do, it can also hold my Sony A7ii with a 24-70mm f2.8 GM lens. I am quite impressed it can hold the weight and still function as well as it can. Only wish is that if it could have a bit more adjustment flexibility with the angle of the legs, there are only 2 settings. All in all, still a great product and seems pretty sturdy when i went hiking and as well for night shots of the stars.
