Camera focal lengthes

an 8 mm lens is always an 8,9 or 10 mm lens. that's just the way it is. it could be a 6 or 7 mm too, but that's not as common.

Huh?
I don't get what you're saying.
Are you saying that a camera lens marked with 8mm could actually be a 6mm, or a 10mm?
This doesn't make any sense to me.
Please clarify

yes. weird, huh?

actually, it doesn't usually vary that much, but there are some bad examples. i have a lens for my still camera that they claim is a 28, but it's more like 32 -- or the 35 mm i compared it to is a 32. ;-)

I have been comparing the wide angle view on certain cameras. On my Elmo 260 SXL which has an 8 - 48 lens the wide angle coverage appears wider than the wide angle position on my Fujica Z850 which has an 8 -64 lens. Is it possible that the Elmo viewfinder shows more of the field of view than the camera lens or that the Fujica viewfinder shows less. (I am ignoring the additional area at the left hand side of the Elmo viewfinder that shows the exposure in making the comparison).
