Hi all,
I wonder if you can help me understand something. I've been reading about lenses and have come across the concept of focal lengths. I've seen that at the wide angle, lenses can have focal lengths of 35mm, 28mm, 24mm and 20mm for example. My question is, in technical terms, what do these numbers mean? What is the difference between 20mm and 35mm?
Thanks,
Sachin
