Focal Lengths
OK. So now let's talk about focal lengths of lenses and why they might be useful. So standard lenses have a focal length between 35 and 70 millimeter. The focal length number tells us how zoomed in or out the lens will be. So the higher the number, the more zoomed in and the lower the number, the more zoomed out and the wider the shot a zoom lens will actually have two numbers, for example, 24 to 70 millimeter. This means the most zoomed out or the widest a shot will be is 24 millimeters and the most zoomed in it will be is 70 millimeters. If you just have one number on your lens, then it'll be a prime lens. For example, 55 millimeters. If you want a slightly wider shot, then you may wish to consider something like a millimeter. This could be useful if you have a tight space or for shooting street photography or landscapes. A more general purpose focal length may be 35 millimeter, which is what I'm using. Now, I use this focal length as it looks natural and doesn't warp any of my feat...
ures. But still allows me to get a bit more of the background and shot. So if you're in a tight space, but you still want the subject to look natural and you also want some of the background and shots. The 35 millimeter should be good for portraits around a 50 to 55 millimeter will often be used as this is the similar focal length to what I see and will look very natural. Ok. So that's a quick overview of focal lengths. Thanks for watching and I'll see you in the next one.
