I'm sort of new to this game, so bare with me...

First off, how do you pronounce the word 'cine'? I know how it sounds in the word cinema, but what about words like telecine, etc?
Secondly, if I get a 2× telephoto lens and stick it on my 18× camera, do I then get 36× overall zoom or just 20× (in other words, does it add or multiply the zoom factors)?

Any help appreciated ...
Thanx

Cine in pronounces 'sinny'

Lenses magnify, so you'd get 36x

If you get a 2x telephoto lens converter it doesn't alter the overall zoom factor, so you'll still have an 18x zoom, it's just that the focal lengths have changed.

Let's take an example. If you have a 4 to 72mm zoom on your camera and screw in a 2x telephoto converter, what you now have is an 8 to 144mm zoom lens. The focal lengths have changed (they've all been multiplied by 2), but you've still only got an 18x zoom.

If by some magic you could zoom from 4mm to 144mm then yes, I'd agree that you'd now have a 36x zoom, but it's not possible to do this.

Its the same with wideangle converters. If you buy a 0,7x converter you'll change your lens into a 2,8 to 50,4mm zoom - still 18x I'm afraid.

Hope this explains things.

Correct as ever, Tom.

Just thought I'd trhow this one in and then duck. When television first started in the 30s, the receivers were called kinescopes, with a hard k. That name was dropped after the war, and I've never found any written reason for the name. The soft c in cinema is correctly used in telecine as a conjoining of two abbreviations, television and cinema.

So there

Without declaring my age I can recall my late father talking of going to the kinema (cinema) and the kinematograph. The derivation is of course from the greek - kinema, movement. Presumably the k got softened to the c through usage.
