I didn’t understand the last comment – why might the subject look out of focus at 15′ through the viewfinder but then be in focus when the shot is taken?

From what I know, …
For example the 18-55 mm lens has a zoom ratiot of 55/18=3.05 x. Did that enlighten you?
From what I know, everything below 28 mm is wide angle, 28 to 50mm is standard and everything above is telephoto. To calculate optical zoom on a DSLR zoom lens (given it isn’t a prime or fixed focal length lens), simply do the ratio between the maximum focal length and the minimum one

Thank you. It took some time to understand this when I was starting (back in the 80’s). Then I got this lens and the light bulb went on.

I think this is a really good video that helps to explain f-stops. I work as a photographer and don’t think I could explain it every remotely near as well as it is explained here. Every new photographer should watch this video!!!
