The Working Distance Myth

The Internet is filled with a lot of wonderful things. Unfortunately it’s also filled with a lot of misinformation. You’ll hear people claim that some lenses are better than others due to the working distance, and how one lens is a better “bug lens” than another because the working distance is better. Well, I’ve only been shooting macro for a year and a half but I’ve already learned one important aspect about shooting insects. Critters fall into two distinct categories:

Those that will let you get close and those that won’t…

It really doesn’t matter what macro lens you have attached to your camera. If an insect stays put, then it will let you get close and you’ll take a picture of it -period. The lens, and the gear in general, does not decide how close you can get –the insect does. Now you might find it easier to work with a 100mm lens over a 60mm simply because you’ve got more room to maneuver with the longer lens. But shooting with a long focal length macro lens will not guarantee close shots of anything.

You’re skill at getting close is what counts.

Take the head shot that’s included with this post. I saw several dragonflies that day, but few would let me get next to them. But I know from experience what to look for and when I spotted one feeding from a perch I tried my luck. I got the full body shot that I wanted, so I backed up and added 62mm of extension tubes to my Canon 100mm macro and the 500D diopter (it was already on the lens) for about three times life size magnification. This dragonfly really liked that perch –he was hunting bees from it and if you look closely at the whiskers you’ll see pollen stuck in them (click on the photo for a larger image). So I knew I could get close and the working distance of my 3x rig, 9cm (about 3.5 inches), made no difference. I know several shooters who are taking insect shots at life size and higher magnification with Canon’s EF-S 60mm lens and it has a working distance of less than 4 inches (about 10cm).

It’s not the gear that makes the difference –it’s you…
