Another winner by Canon. I find this lens very difficult to find faults with. In fact this might be the first time I could not come up with a Con for this lens. Initially I thought the only possible negative I could come up with is that F/4 is not enough for certain astrophotography situations.

Landscape dream lens; 77mm Threads; Sharp images corner to corner even at F/4; IS; Locking Lens Hood

Not really; but in specific astrophotography situations; the aperture is not wide enough

This new ultra-wide angle zoom lens should replace Canon's venerable 17-40mm f/4L optic in their line up of professional lenses. It sports a zoom range of just over 2x and a constant maximum aperture of f/4.

Outstanding sharpness across the frame from maximum aperture; Excellent build quality; Relatively lightweight; Reasonably low distortion; Low CA; Image stabilisation; Fast autofocus; Dust and moisture resistance

Distortion is wavy at 16mm; Far corners remain darker than the image centre; even when stopped down to f/16

Not a lens that I use a lot but it is great for that wedding photo with a difference - the group photo or a close up of the couple with a great background. Also good for interior shots where flash is not permitted

Upgraded from Canon's 17-40 L and the difference in image quality improvement is really noticeable. Images are pin sharp right into the corners even wide open. The IS is handy for low light too. Got some superb night shots of New York with this lens.

It is hard not to be happy with this lens, between its IS & durable yet lightweight build, it is the best wide angle for action sports, landscapes and general purpose shooting. With it being F/4, I've never found it to be a limiting factor and couldn't be more happy with its edge to edge sharpness.

After owning the 16-35mm f/2.8 for 5 years and shoots a LOT of landscape and real estate images, I was intrigued by the great reputation this new f/4 lens was getting. I finally pulled teh trigger, sold the 16-35/2.8 and bought this, and the rumors are all true: the image quality on this lens is...

Beautiful lens. Snapped it up on special at a great price. Wonderful on Canon 6Dmk2.

I was looking for a wide angle zoom lens for my EOS 6D and while the EF 16-35mm f/4L IS USM is not the most affordable option I feel like it's worth every penny. On the 20 megapixel sensor of the 6D it delivers sharpness at every focal length and every aperture from corner to corner. It also shows little to no chromatic aberrations and handles flare very well. All around a professional level lens that never lets you down.

While it's a shame that picture and sound quality haven't been upgraded, the iPhone 13 was great in these regards and the iPhone 14 is, too Excellent display Admirable headphone performance Solid build quality No upgrades to picture or sound Familiar design Notch is still present

Apple's latest non-Pro iPhone is superb - it's just that it's strikingly similar to last year's effort.

Still an incredible smartphone, Brilliant battery life gets a bit better, Excellent camera system gets a bit better

Last year’s Pro hardware, Wireless charging slow by modern standards, No USB-C; it’s now well overdue
