Will a 50mm lens be wider then 18-140mm?
So I have a Nikon d5200 with a 18-140mm lens and I wanna start a YouTube channel. I've looked at the Nikon 50mm lens. Will it have a wider angle then my current 18-140mm lens. If not, what will then?
The 18mm end of your 18-140mm lens is far wider than a 50mm would be!
Thing is that you don't really want anything wider than 18mm for shooting video. It'll look fine so long as you are facing the camera and not moving, but as soon as you start to move the perspective even at 18mm is going to look "odd"!
At a minimum you don't really want to be shooting video with a lens that has a focal length below 24mm, and even 30mm is going to look much better still!
You could have answered this yourself
Just set the 18-140 mm lens at 50 mm and look through the lens.
Logically if you know that 18 mm is the wide angle end of your lens, you would have seen that 50 mm is NOT a wide angle lens. In fact it is a medium telephoto lens when attached to your D5200
If you need a lens wider than 18 mm to use for establishing shots, then look at the AF-S Nikkor 10-24 mm or 12-24 mm lenses. If you do not have around $1,000 to invest in either of those lenses, the look at the wide angle zooms made by Tokina
I'm surprised that someone who owns a mid-level body like the D5200 doesn't know this, plus just by looking at your own 18-140 lens, this should be more than obvious since 50mm is in between 18 and 140mm.
But anyway, the smaller the focal length (e.g. 18mm vs 50mm) the wider the field of view. A 50mm is a normal lens (on a full-frame camera), which means that it has about the same angle of view (not taking into account peripheral vision) and it also has the about the same perspective. By this I mean the way things look is close to the human eye. As you go wide, things will look further away, and things that are close will look larger than things further away. As you go up in focal length, this perspective becomes compressed, so things look closer than they really are. This is why they're great for portraits because the compression of the perspective actually enhances the look of people's faces, while wide angle lenses will distort it and make people look bad.
Of course, you're not using a full-frame camera, so the 50mm will actually have an even narrower angle of view than when it is used on a full-frame camera. On your D5200 the 50 has the same angle of view as a 75mm lens on a full-frame camera. The depth of field that it produces, however, does not change and therefore it does not have the same DOF as a 75mm lens. The perspective doesn't change either, so you will still get the same normal, less compressed look from the 50mm than you would had you used a real 70mm lens.
In APS-H (the format of your camera) any lens with a focal length less than 33mm is considered to be wide angle. 33mm is a "normal" lens on Nikon's APS-H format. Anything shorter than 33mm is now wide angle and anything longer is telephoto.

Hmm, let's see, is the number 50 smaller than the number 18? Well, no it is not!
No!
Set your 18-140 at the 50mm mark - that is what the 50mm lens will be like.
18 is much wider than 50, which is much wider than 140.
In other words, you will have a 50 mm lens if you set the zoom on your 18 - 140 to the correct point.
50mm is included in 18-140mm. See for yourself.
Just think about your question. If 18mm represents the smallest in terms of "mm" That "mm" is also the widest angle of view from the lens. Therefore 18mm is smaller than 50mm. So 50mm is certainly NOT the smallest "mm" of the zoom length. Lets deduct 55mm from 140mm and the answer here is 95mm and 55mm goes into 95mm just short of two times. So you could say that 50mm is a little more than 1/3 the length of a 18-140mm lens. Then you ask what will be a wider angle lens than the 18mm. If your brand camera maks a 15mm lens THAT would be wider than an 18mm lens or the 18mm end of your zoom lens. But I think you also want a lens that accepts light faster or is more sensitive like a 50mm f/1.8 or 50mm f/1.4 lens. But in my experience there are NOT many or if any lenses which are faster than f/3. Or f/4.
