Unravel the “secret code” in a lens name, and find out about the story behind the red rings and white bodies on some lenses.

- When you shoot macro On many macro lenses, you usually have to be at the closest focusing distance to achieve the maximum magnification. But you don’t always want to be too near your subject, especially if you are shooting sensitive creatures such as insects.  Tip: Use a a telephoto macro lens like the EF180mm f/3.5L Macro USM (C.F.D: 0.45m) or the EF100mm f/2.8L Macro IS USM (C.F.D: 0.3m) to achieve life-size magnification even when shooting from some distance away.

Know this: Compact cameras may carry specifications such as “1cm macro”. This refers to the working distance of the lens, not the closest focusing distance.

Canon EOS cameras have a focal plane mark on the camera body. The image sensor is located under this mark. The focusing distance is measured from this mark to the subject. If the lens has a distance scale, the shortest distance indicated on the scale is equivalent to the closest focusing distance.

In contrast, the working distance (see B below) refers to the distance between the front end of the lens and the subject.

Other than brightness, what sets an f/2.8 lens apart from an f/4 lens? Using the EF70-200mm f/2.8L IS II USM and the EF70-200mm f/4L IS USM, I will show how the two differ by comparing the apparent resolution and bokeh size. (Photos by: Ryosuke Takahashi)

Tip: There are pitfalls to shooting too close It’s great to have the freedom to be able to shoot close to your subject, but too close and the lens hood and lens shadow might be captured in your shot—not ideal for some shooting scenes! Take the necessary precautions. If your lens doesn't have built-in Macro Lites, consider if you want to invest in a flash that is designed for macro photography.

Many people think that the closest focusing distance and the working distance of a lens are the same thing. They are related concepts, but they are not the same!

This series is all about answering questions regarding lenses that you thought you knew but didn’t. In this article, we look at one lens specification that you might want to consider when you buy lenses or choose which one to use: The closest focusing distance, also known as the minimum shooting distance.

- When you are shooting in a tight space If the closest focusing distance is big, you will have to stand further away to focus on your subject. Framing and composition aside, this is also why it would be hard to use a telephoto zoom lens like the EF70-200mm f/4L IS II USM (C.F.D: 1.0m) to photograph someone sitting right across the table from you in a small, cozy café.

He is a member of the Society of Scientific Photography (SSP).

A lens that has a very short closest focusing distance allows you to achieve sharp, in-focus images with a shorter working distance.

The closest focusing distance of a lens (see A below) refers to the shortest distance that must be between your subject and the surface of the image sensor (the focal plane) for the lens to focus. It is not affected by the length of your length, and does not change even if you zoom your lens.
