Historically, how have lens manufacturers chosen the ranges (the minimum and maximum lengths) for their zoom lenses? Is there a specific reason for the lengths?
For example, why choose to manufacture a 24-70mm lens? Why not make it 18-72mm, 20-100mm, 120-300mm or some other range?
I suspect there is a reason for this but I don't know what it is. Just curious.
Thanks.
