It went “zip” when it moved and “bop” when it stopped,
And “whirr” when it stood still.
I never knew just what it was and I guess I never will.

THERE ARE MORE OLD LENSES THAN THERE ARE OLD CAMERAS. There’s a reason for this. Bodies come and go like spring and fall dress collections. Lenses are the solid, reliable blue jeans that never go out of style. Lenses hold their value for decades, often selling for (or even above) their original asking prices. Bodies become landfill.
Many times, when people believe they have outgrown their cameras, they are actually just in need of glass that performs better. The importance of selecting a lens is as important in the digital age as it was in the film era. The eye through which you visualize your dreams has to be clear and precise, and so does the thinking that goes into its selection. That process, for me, breaks down into three main phases.
First, before you buy anything, raise a prayer of thanks for the Holy Internet. There is, now, not only no need, but also no excuse to buy the wrong lens. Read the manufacturer’s press releases. The reviews from both pros and amateurs nearest your own skill level. And be ecumenical about it. Read articles by people who hate the lens you think you love. Hey, better to ID a problem child before he’s living under your roof. Watch the Youtube videos on basics, like how to unpack the thing, how many parts it has, how to rotate the geetus located to the left of the whatsit to turn it on. Find out how light efficient it is, because the freer you are of flash units and tripods, the better for your photography. And, at this early shopping stage, as with all other stages, keep asking yourself the tough questions. Do I really need another lens, or do I just need to be better with what I already own (which is cheaper)? Will it allow me to make pictures that I can’t currently make? Most importantly, in six months, will it be my “go-to”, or another wondrous toy sleeping in my sock drawer?
Assuming that you actually do buy a new lens after all that due diligence, nail it onto your camera and force yourself to use it exclusively for a concentrated period. Take it on every kind of shoot and force it to make every kind of picture, especially the ones that seem counter-intuitive. Is it a great zoom? Well, hey, it might make an acceptable macro lens as well. But you’ll never know unless you try. You can’t even say what the limits of a given piece of glass are until you attempt to exceed them. Find out how well it performs at every aperture, every distance, every f/stop. Each lens has a sweet spot of optimum focus, and while that may be the standard two stops above wide open, don’t assume that. Take lots of bad pictures with the lens (this part is really easy, especially at the beginning). They will teach you more than the luck-outs.
Final phase: boot camp for you personally. Now that you have this bright shiny new plaything, rise to the level of what it offers. Prove that you needed it by making the best pictures of your life with it. Change how you see, plan, execute, edit, process, and story-tell. See if the lens can be stretched to do the work of several of your other lenses, the better to slim down your profile, reduce the junk hanging around your neck, and speed up your reaction time to changing conditions.
Work it until you can’t imagine how you ever got along without it.
