Justin has completed his review of the Canon EF 17-40mm f/4L ultra wide angle zoom lens from Canon. For a lot of people, this is their first wide angle zoom and becomes a workhorse.
I know one landscape/nature photographer who uses this lens extensively and it’s used for about 75% of images that he sells, and he sells a lot! This is a great lens for publishing and using all the time. I have a hard time recommending the 16-35 f/2.8L II to anyone other than an event photographer. The EF 17-40mm f/4L is a workhorse that is reliable and doesn’t cost a whole heck of a lot.
Justin likes it a bit less than I do, but the review is pretty positive.
