Ok, so I know target size affects angle of veiw at a given focal length.
Heres my question: I am so used to using lenses marked for 2/3" CCDs that in planning which lenses I need for a mini-35 setup is making me a bit uneasy. I am looking for a range similar to an ENG news lens, something around 7.5-110mm (calculated for the 2/3" chip) but need that to work with the 35mm target of the mini-35. I think we are going with some primes so this is all the more important for me.
is it a linear conversion? IE if the diagonal is aprox twice as big on the 35mm to the chip, does that mean that a 25mm 35mm prime equates to a 12.5mm chip?
If anyone knows how to calculate that I would be very thankful.
(not looking for actual focal length, just equal angle of view. these wont be anamorphic or anything complicated like that, just standard round lenses.)
