Canon 100-400mm f/4.5-5.6L IS II Lens Announced

(Updated) Canon has announced the long-rumored replacement to the venerable 100-400mm L lens. It is the EF 100-400mm f/4.5-5.6L IS II.

The lens it replaces has been a very valuable “go to” lens for many photographers who wanted more reach, a reasonably small package, good optical quality, and the flexibility of a zoom. I’ve been an enthusiastic user of the older version for some time now.

Recently Canon has updated or augmented their lens line-up to improve the offerings in certain categories. For example, earlier this year they introduced their ultra wide angle zooms by adding a new EF 16-35mm f/4L IS lens. That lens has been a real success, not only adding image stabilization to lenses in this class for the first time, but also providing excellent resolution across the frame — more so than either of the lenses that many photographers used before it was introduced.

For some time, many have felt that there was a lot of potential for updating the 100-400. Although it is good performer in many ways, there has been room for improvement. More modern IS systems can provide up to 4 stops of stabilization, while the older lens only provides perhaps two. The older lens has good image quality, but it could be better in keeping with more recent lenses from Canon. In fact, rumors about the introduction of the updated 100-400mm zoom have been floating around for years.

We don’t know what the optical performance of the new lens will be yet. As I write this I have seen no real reviews. (I have seen some “reviews” that are mostly lists of specifications and speculation.) When we do see them, it will not surprise me at all if this lens provides valuable improvements in the same way that the 16-35mm f/4 has. Here is some of what we do know from Canon specifications:

  • Rather than the “push-pull” design of the earlier lens, this one has a more familiar rotation ring to change the focal length.
  • As was the case with the older model, the front of the lens extends as you zoom. This means that the lens is more compact when packed.
  • Image stabilization has been updated to provide up to four stops of stabilization — especially important with longer focal length lenses.
  • Other features include 9 blade diaphragm, the familiar 77mm filter thread diameter, and more.

The list price of the lens is $2,199. That may seem like a lot of money, but if it provides the sort of image quality we all expect it is actually a rather good deal for a lens with these capabilities.

Update: I have now had a chance to look at the MTF charts for the new lens (available at the Canon web site) and they suggest that the new zoom should be a very good performer in terms of image quality. The chart suggests better image quality than the existing 100-400 (which is quite decent) and the 400mm f/5.6 prime.

I expect that this lens will be in short supply at first — for the usual reasons related to any new product introduction, but also because of a pent-up interest in the update. The lens has been announced but is not yet available — though you may preorder it if you want to be first to get one.

As for me, there is a very good chance that I will get a copy of this lens before too long. In fact, I’m leaning more and more towards placing a pre-order — something that I rarely do.

Canyon Reflections

“Canyon Reflections” — Reflections of canyon and sky in the muddy bed of a canyon stream

I was tempted to title this “More Mud.” But I didn’t, even though canyon mud is a very interesting subject throughout this area of the Southwest. I had been in one south Utah location for a few days and it was time to travel to different area to meet up with a friend. Rather than taking the paved routes I decided to follow about 50 miles of gravel back roads — the mileage was shorter but the time was longer. Better yet, this route took me past several interesting sites that I wanted to explore a bit.

One of these is a little canyon that I first visited a few years ago with friends. In fact, this spot was my very first time in one of these deep and narrow canyons. I recall that the entire experience was foreign to me on that first visit — from walking up the middle of a shallow running stream, to shooting in midday for the best reflected light, and the new and unusual (to me) sights and sounds of this part of Utah. So I figured that it might be fun to make a brief stop on this drive and wander back up the canyon for an hour or two. The canyon has many attractions, but one is that its regularly running steam keeps the canyon floor mud damp and reflective. Another is that high red rock walls reflect lovely bright colors down onto the water and the mud. After hitting my turnaround point, as I retraced my steps back down the canyon I paid special attention to the textures and reflections in the mud, and I was excited to find this spot that combined the red sand, the deep blue reflection of sky, the reddish reflection of canyon walls, and the warm light reflected down into the canyon.

Crystal Bay, Lake Tahoe

Crystal Bay, Lake Tahoe
“Crystal Bay, Lake Tahoe” — Blue water and light above Crystal Bay, Lake Tahoe

My annual hunt for aspen color took me to the Lake Tahoe area in early October. I realized that although I’ve gone to Tahoe for many years that I have very few photographs of the area. So often Tahoe has been a place to go for other purposes, such as skiing or a cabin stay, etc. And, frankly, Lake Tahoe is very busy and, in many ways, an urbanized place — so my nature and wilderness instincts are often a bit frustrated there. But it is a beautiful lake, and I saw more of that when I went there with photographic intentions.

The underlying reason this time has to do with a project related to fall color in the mountains of California. I’ve covered many other Sierra fall color areas, but I needed more material from the Tahoe area. So I spent an evening, a full day, and part of a morning doing some exploring. The “full day” began with a drive to the Carson City, Nevada and then north towards Reno and back toward Tahoe via Mount Rose. There were quite a few aspens along this part of the drive, but I couldn’t stop much due to road construction. Then I did something I’ve done a number of times before — I circumnavigated the lake, paying special attention to fall color. I realized that there is quite a lot of it, even if much of the color is in areas filled with cabins and resorts. This photograph overlooks the northeast part of the lake from the roadway descending from Mt. Rose.

Distorted reflections of a crane and Chicago buildings

Every so often I wonder about architects. For the most part we think of them — or at least I do — as folks who are as much about logic and structure as they are about design and form, and when they are about design they don’t usually seem to be particularly whimsical. (With notable exceptions.) Whimsical doesn’t fit the image or the expectations of the typical big business clients who might commission such towers as those found in an urban center like Chicago — these see like people who are more interested in cultivating an image of stability and wealth and power.

But then I look at the window reflections that are the inevitable result of placing plexiglas covered buildings in close proximity to one another and I have to wonder. Are these folk aware of the almost hallucinogenic shapes and forms that appear on the sides of these buildings? In fact, how many people on the streets are away of the abstract and bizarre visual show that is often going on overhead? Here, against the clean and mathematically perfect face of this building, neatly divided into equal grids of alternating shades of blue, appear bizarre visual monstrosities. A red construction crane warps upwards and leans precariously to the right as its upper elements simply fall apart into twists and curlicues. Sections of the reflected buildings are alternately minimized and expanded to gross degrees, and if you look closely at the resulting patterns you might find anything from aerial fish to faces to whatever else you want to imagine.
