Focal Length - A Simple Explanation

May 12, 2018

I am constantly surprised by the number of photographer's who come to me for private lessons who don't really know the focal length of their lens.  

Many of them don't even know the importance of different focal lengths and the impact they have of their photographs.


One of the most common areas of confusion is between telephotos and zooms, with a sizeable majority mixing the terms up, believing they are one and the same thing.

In this video, I try to explain in simple terms, what focal lengths are.  


All the assumptions in the video are based on a 35mm film camera or a full-frame digital camera being used.  Once you put any lens on a crop-frame camera body, things get slightly more complicated.
