What is a 17-40mm lens used for?

The 17-40mm focal length range is great for group pictures, environmental portraits and full body pictures. Stand back and make a person part of a wide landscape shot. If tighter portraits are your interest, look for a lens that gives you at least an 85mm – 135mm equivalent focal length.

Is canon 17-40mm worth it?

The Canon EF 17-40mm f/4L USM achieves a high ranking for an ultra-wide angle lens with DxOMark score of 21 points. Peak sharpness at 15P-Mpix is perhaps a little behind the latest designs but it’s still very good. Like so many zooms, it’s better at the wider end where it has good uniformity, even wide-open.

Is the canon 17-40mm f/4 L Worth the price?

All in all, the 17-40mm f/4 L easily justifies its premium price with top-notch optical performance. The full-frame test results for the Canon 17-40mm f/4L demonstrate to some extent just how much full-frame cameras demand from even excellent lenses in the corners. The 17-40 f/4 is an excellent lens, remarkably so on the 20D.

Does the 17-40 L come with a lens hood?

The 17-40 L ships with a Canon EW-83E lens hood and a Canon LP1319 soft lens pouch. The shape of the hood (very wide and very short) makes one question whether it actually helps. It does almost nothing for lens protection – and nearly nothing for image quality when used on a 1.6x FOVCF body. It also makes storage inefficient.
