Cine lenses ??

[cadibob]

Hi, bonjour

Which could explain me why the movie lenses are much more expensive than others?

Qui pourrait m'expliquer pourquoi les objectifs cinéma sont beaucoup plus chers que les autres ?

Thanks.

They are made to be consistent. Size, Tstop, colour rendition etc. All takes money to get the design and manufacturing to that level.

Basically, what Berek said above, and also they have much less focus breathing (where the field of view changes slightly along with the focus), and typically have very round bokeh balls as opposed to cat eye, throughout the frame.  So the optics tend to be more complex and made to higher tolerances.

All of that. Additionally, cine zooms are 99.99% perfectly

parfocal over their whole range at all distances. That's a

lot of very expensive, complex precision construction.
