In Praise of the Canon 24-105mm f/4 L IS

(Note: Though Canon no longer sells this lens, it is still around and may be a useful lens for photographers using DSLRs.)

Sometimes it seems like the Canon 24-105mm f/4L IS lens doesn’t get the respect it deserves. It probably doesn’t help that it is often described as a “kit lens” because Canon bundles it with some of their full frame DSLRs. Having a maximum aperture of only f/4, it lacks the f/2.8 aperture found on some of  the other Canon L zooms. It uses a “telescoping” zoom design that extends the front element when the focal length changes, and some mistakenly associate this design with lower quality lenses. It certainly doesn’t have the panache of the high-end, large-aperture primes, with their big  f/1.4 or f/1.2 maximum apertures, nor of the big and impressive f/2.8 L zooms, nor the exotic and equally expensive tilt/shift lenses——nor does it have their correspondingly large selling price.

Announcements from Nikon and Canon

Today Nikon announced two new 36+MP full frame DSLRs, the D800 and D800E, and Canon announced a long-awaited update to their EF 24-70mm f/2.8 L zoom. I’ve posted a bit more information in a new entry on the Deals page.

Brief Thoughts on The Life of a Photograph

The image I posted earlier today both here at the blog and on Google+ got me thinking about the various ways that a photograph can “come to life.” This particular image followed a path that several other images that I consider to be among my best followed – namely, it languished in my raw file archive for nearly a year before I rediscovered it recently while going back through the old files. I recognized this pattern some time ago, and I now make it a habit to revisit all of my (thousands and thousands of) raw files about a year after I shoot them.

Why didn’t I “see” this image when I first reviewed raw files right after the shoot? I’m not entirely certain, but several ideas come to mind. Sometimes at the time of the shoot I have a strongly fixed notion of how I want to portray the subject , and as I shoot I’m already categorizing exposures by how well they correspond to this preconception. So when I initially go through the raws I may be mostly looking for what fits my expectations as opposed to looking objectively at what works on its own merits. Coming back a year later allows me to better see the image for what it is, without having my judgment so affected by prior expectations.

Related to this is the sheer number of images and how one deals with them in the post-processing workflow. I may begin with what I think are the most promising couple of images from a shoot and then take them all the way to a print-ready (or actually printed) stage. Once I’ve done that with the first selects from a given subject, I’m more likely to move on to other subjects – and potentially leave other good images in the dust.

There is a lot more to say about this, I think, but I’ll save the longer explication for another blog post in the future. Does anyone else make a practice of doing a full review of raw files at some future date?

Megapixel Mania – An Extended Riff

I read (yet another… ;-) megapixel rant somewhere online yesterday, and it got me thinking again about the fixation on megapixels as a measure of camera “value,” and the odd and sometimes irrational ways that people respond to this issue. It is well known that over the past decade or more, as digital photography technologies have become more and more prevalent (displacing film in many areas), camera technology has continued to advance in many ways. Among these advances is the ability to increase the number of photosites on sensors of a given size – e.g. give us “more megapixels.”

The responses to this tend to fall into three broad categories: Continue reading Megapixel Mania – An Extended Riff
