There are different purposes for different focal lengths. If you are shooting a group of people having some sundowners next to the game viewer, you would want to use a wide angle lens. You would then be able to include all of your subject in a single shot and not need to move further away. If you are shooting wildlife however, you would need a longer focal length lens, because there is often a limit to how physically close you can get to the animal.

It is often incorrectly assumed that the focal length is measured from the front to the rear of the lens when, in reality, it’s the distance between the point of convergence in your lens to the sensor or film in your camera.

Wide angle lenses have smaller focal lengths than telephoto lenses. The majority of wide angle lenses are 35mm or smaller whilst telephoto lenses start at 70mm and go up from there. Wide angle lenses include more of a scene, while telephoto lenses generally include only a small part of a scene.

In order to illustrate this, I have taken different photographs of the same subject matter at different focal lengths. Take a look at the shots below with their accompanying mm values. Note that I was using a Canon 7D mkii, which has a crop sensor, which I will explain further in another blog post.

Good post about focal length. I’ve found that having a 70-200 2.8 works well considering the distance you often find yourself from an animal. That being said, sometimes I wished I had a bit more length so have now purchased a 1.7 teleconverter which only reduces the f-stop by 1.5 stops. Sometimes we just have to carry two cameras-each with a different focal length as you never know what you’ll see and changing lenses on the run is never great because if the dust. Thanks!!

Our Management found the future during the holidays. They are convinced you can do camera inspections simple and cheap with ai and a computer. I'm now searching for free or cheap AI engine that can analyse pictures for tests, after being teached what is a good product and a bad one (I done some tests with google and Microsoft, but not do successful). I know there are Keyence and Cognex solutions that can do this (partly) but they want me to look into a solution that are cheaper. Do any of you did something like this before?

However, a basic understanding of a few of the more common ones will not only help you make a decision when buying a lens, but will also go a long way towards helping you capture great wildlife shots.

‘MM’  is the focal length of the lens. All lenses have a “mm” number printed on them; some have a range of focal lengths. These numbers can vary hugely, from 8mm (a fisheye lens), all the way up to 1000mm and even beyond.
