SINCE THE 1990’s, THE MOST COMMON BASIC HUNK OF PHOTOGRAPHIC GLASS for new DSLRs has been the 18-55mm wide-angle, dubbed the “kit lens”. It allows beginners to move from landscape-friendly wides to moderate zooms without switching lenses. Depending on how much a given shooter experiments, the kit can allow for a lot of nuanced compositional options between the lens’ range.
If you find yourself shooting at the widest angle most of the time, then you are really using an effects lens, since, at 18mm, the lens is more than wide enough to distort angles and distances in ways that, while dramatic, don’t reflect the way your eyes actually see. This makes for expansive vistas in crowded urban streets and a little extra elbow room for mountain views, but is substantially more exaggerated than focal ranges from 35-50mm, which produce proportions more like human eyesight. However, the focal length you eventually choose has to be dictated by what you care to create; there can’t be any yardstick than that, all people’s opinions off to the side.
I have found a personal sweet spot by going a tad narrower, back to 24mm, and I also work with a dedicated prime lens that will only work at that exact focal length. By trimming back from 18mm, I find the distances from front to back in an image are a little more natural to my eye, and that I still have a yard of room from side to side without ushering in that Batman-type bending of perspective.
For comparison, I have re-shot subjects that I’d photographed at 18mm and found, at 24, no loss in impact. In the images in this post you can see the difference in how the two settings frame up. The composition in the 24 is a little tighter, but, if that’s not wide enough for you, you can simply step back a bit and there’s the same composition you saw in the 18, albeit with a little more normal proportion.
The most important thing with a variable focal length lens is to give yourself the flexibility of being able to get good results all through the focal range, simply to avoid getting too comfortable, i.e., sliding into a rut from always doing everything in the same way. Putting yourself into unfamiliar territory is always a good route to growth, and playing with your gear long enough to know everything it has to give you is the best way to periodically refresh your enjoyment.
