I understand the lens size affects how "zoomed in" the picture looks for example 22mm is very zoomed in compared to 2mm a wide angle.
Where I am having trouble is truly understanding varifocal. Does varifocal only mean the lens can be moved from one to the other effectively zooming (either manual or through software). I feel like i have been trying to read up on this for a week now but for some reason I am just not getting it.
From what I can gather varifocal would be only good if you are unsure of the horizontal angle you want to cover?
(I think I have been trying to absorb too much)
