Without a whole lot of fanfare, today Canon announced a new EF 16-35mm f/4L IS wide angle zoom. While actual copies are apparently not yet “in the wild,” judging by reports and information from Canon and elsewhere, it sounds like a lens with some very interesting possibilities.

At first blush, one might imagine that it is simply a less expensive version of the EF 16-35mm f/2.8L II lens that has been out for some time now. (That is a fine lens for many purposes, notably for full frame shooters doing handheld ultra-wide photography in low light.) It shares the same focal length range, but the maximum aperture is not quite as large. (There is a similar relationship between the EF 24-70mm f/2.8L II and the less expensive EF 24-70mm f/4L IS.)

However, the new lens has some distinctive features that set it apart from the f/2.8 16-35, and also from the venerable 17-40mm f/4 L.

• Unlike either of the two ultra-wide alternatives, this lens is equipped with image-stabilization (IS). Some presume that IS would not be useful in a wide angle lens, but there are a number of situations in which the extra 3-4 stops of low light handheld shooting capability will come in handy. It is also likely to appeal to those shooting DSLR video.
• The MTF charts (a way of graphically representing lens performance) for the new lens look very good. While the existing 16-35mm and 17-40mm Canon ultra-wide lenses have been very important to many photographers, they are not known for outstanding resolution, especially in the corners. The charts for the new lens indicate that it should be significantly sharper overall, and especially in the corners and at the largest apertures.
• It may seem like a small thing, but the new lens uses the common 77mm diameter filter threads—the same that are found on a number of other L lenses, including the f/2.8 70-200mm zooms. (The previous f/2.8 16-35mm lens uses a larger 82mm diameter.) For photographers who already have 77mm filters—including some who might consider moving to this lens from an existing 17-40mm lens—this is a factor to consider.
• The price is actually quite good. The lens is not cheap at a projected list price of $1199. However, by comparison to some similar recent Canon lens releases this is not bad at all, especially when you consider that it is an IS lens.

Who may want this lens? I suspect that quite a few landscape photographers and those shooting similar subjects will like this lens more than the older 17-40mm L lens. I’ve used the 17-40 for a long time and it is a very useful lens, especially for shooting at smaller apertures from the tripod with a full frame camera. However, the new lens seems to improve on its performance in significant ways, particularly in the area of corner performance. In addition, while most of us really think of the 17-40 as pretty much just a landscape lens, the improved wide-open performance and image stabilization will extend the usefulness of this lens in low and for handheld photography.

I’m impressed enough with early reports that I’m giving serious consideration to picking one up myself. The lens is not yet available for purchase, but you can pre-order a copy from B&H. At the moment, I’m “that close” to doing so!
