What is 28mm wide angle lens mean?

Answer 1

A 28mm wide angle lens is basically a wide angle lens for a 28mm camera. The book definition for wide angle lens it... "a camera lens having a wider than normal angle of view (and usually a short focal length); produces an image that is foreshortened in the centre". In may words, "A lens that you put on your camera that makes the frame (frame- what you see) wider. Ex. If your zoomed out all the way and your pointing your 28mm camera at a chair. You can see the whole chair and just the chair. If you put on your wide angle lens, you can see more. You could fit two of those chairs in your frame now. Basically, it makes your frame wider.
