Bought this lens prior to going to Italy. I found the 16-35 mm range with IS the ideal lens for narrow Italian village streets as well as the many outdoor scenes. I have included a few pictures shot with this lens on a 5DMKIII.

This is a spectacular lens! Fabulous image quality with minimal distortion, great contrast and color saturation. It is heavy, but the quality of construction and the resulting images are well worth the price and extra weight.

Great lens in its class, fast delivery home, very well, I fell in love with this lens, it is very wide, sharp, nice colors, fast AF and the rest. There is one problem canon did not update and my camera does not recognize the lens, i can not make jpeg shots, canon camera 5dm3

I wanted this lens just for landscape photography. I also have a Canon 24-70mm F/4 which is great. It's just that sometimes I needed a wider view. This lens deliveres and is perfect for any landscape photographer.

"When I bought my 6D a year and a half ago, it comes with the 24-105mm lens. For a while I was content with it. However there were times when I'm shooting my clients backyard projects, or interior and exterior scenes when I can get wide enough.

I converted to L series lenses a few years back and was blown away by the quality of the images and the lens build quality. Having said that, my budget doesn't stretch to the f28 lenses. The f4 lenses are on my radar and im very happy with the results.

Abbe paglagayo keya? price se 1 lakh kam kar, jo maan me aya likh diya

Pros - Ultra-wide angle - Great image quality throughout the image - Includes IS - Great price for what you get Cons - f4, but expected given the price - Minor barrel distortion, but totally acceptable given the wide angle - Physically a bit larger than I would have liked, but is acceptable

Image quality is fantastic and is fairly easy to operate though is a bit bulky. i now need to review my own technical skills.

Bulky

For the first few days I was dissapointed but later i have realised this is much better for shooting flats than the Zeiss 18 3.5 ZE i had before. It's great for wide angle shoots and ok for portraits at 35mm but I wish Canon would just make lens like Zeiss 15mm 2.8 for the price of the 16-35 4 IS

Versatile, IS is a killer good, distorsion in not bad; Sharpness is not too bad in corners

I guess it's sharper than other canon wide zooms but not as close as sharp as Zeiss 21mm 2.8 ZE; Out of focus part seem a bit weird as if they are result of camera shake
