Thanks for this video. This may be the single best video on photography that I’ve seen in the last year. It brought all these competing variables together for me in a short, easily understood video. Nicely done.

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.
Had to share it.

How do you covert the DSLR lenses zoom to optical zoom(ex. 5x optical zoom)?
What focal lengths are wide angle, standard and telephoto?
Thanks
