Canon EF 100-400mm f/4.5-5.6L IS II Lens — A First Look

(Note: Updated 12/24/14 to add thoughts about “who should buy” this lens.)

Canon recently released the successor to their venerable 100-400mm telephoto zoom lens, the new EF 100-400mm f/4.5-5.6L IS II lens. I have relied on the older model for some time now… but my copy of the new lens arrived a few days ago. Now that I have used it for a day of wildlife and landscape photography I would like to share some first impressions

First, a few technical details. The new lens covers essentially the same range as the older model — a focal length range of 100mm to 400mm and a variable aperture range of f/4.5 (at 100mm) to f/5.6 (at 400mm). Both lenses use a zoom mechanism that extends at longer focal lengths. However, there are some technical differences:

From time to time I adapt things that I wrote elsewhere and re-share them on the blog. The following is something I contributed to a discussion about a question from a newish photographer who wondered how important it would be to upgrade his camera. 

I’m all for better image quality — which contemporary cameras, software, and printing processes provide in spades. And there is no question that, all else being equal, a photograph captured on a larger film or sensor format can potentially resolve more detail, and may improve other image parameters including dynamic range and noise.

As they say, “So stipulated.”

But the question (which was about choosing a sensor format) deserves a more nuanced and contextual answer than that. Fortunately, the most accurate and useful answer involves quite a bit of that nuance. I think it really comes down to something like, “Will replacing my cropped sensor camera with a full frame camera make my photographs look better?”. The best answer begins with, “It depends.”

As to the question (which also came up in the original discussion) of what is important in a photograph, image sharpness is not unimportant in many cases. (Though there certainly are photographs whose “goodness” is perhaps at least partially because they are blurred — softness and blur are not always things to be avoided.)

I think the issue in photography discussions is frequently about the balance among issues that affect the quality and effectiveness of a photograph. Here, it is not uncommon for some folks to exhibit a misplaced focus on the technical stuff, accompanied by insufficient attention to other things that are more important to their success as photographers.

Too Many Aspens!

Yesterday I realized that I had sort of forgotten a huge batch of aspen photographs from this fall in the eastern Sierra Nevada. How can one “forget” a big batch of such photographs, you ask? I simply became busy working on several other projects and after I moved on to them I stopped thinking about the earlier work.

I have so many of them — with more to come! — that I’m not going to string them out and post one at a time. Instead, here is one big batch of them all in one post. To save typing, all are from the eastern Sierra Nevada in October 2014

Pick the Right Friends… (Morning Musings 9/29/14)

If you are ever in the wilderness and you want someone to take a photograph of you, you could hand your smartphone to the nearest person and hope for the best. However, I have a few suggestions (slightly tongue-in-cheek) that might improve the odds:

  1. Arrange to be in the company of one of the best landscape photographers working today. (Yeah, that’s you, Charlie Cramer.)
  2. Make a photograph of him at work and hope that this inspires him to photograph you doing the same thing.
  3. Be sure to place yourself so that dramatic golden hour light hits you in partial profile.
  4. Be sure to position yourself against an appropriate background.
  5. Gaze attentively and thoughtfully into the distance. ;-)

Bonus hint: Be sure to level your tripod first, or your photographer friends may never let you live it down. ;-)

Here’s a photograph of Charlie at work, too

In all seriousness, when you are out shooting, do photograph your fellow photographers. Each of us needs photographs of ourselves, and a photograph by a friend (or of a friend) is a special thing.

Thanks, Charlie!
