I took a weekend hike at a local wildlife preserve, McLane Creek Nature Trail. Not a long hike, but I am always amazed at what I find in this part of Washington State in the dead of winter!
I just sold my EF 17-40mm f/4L which has been my main lens for years, and replaced it with the EF 16-35mm f/4L. Both are excellent lenses, but the “16” costs another $250 to $400 more (depending on where you buy). It has image stabilization, which the “17” does not, it’s slightly wider, but it’s missing 5mm on the telephoto end of the zoom range.
