Hello. Not sure where I should post this, since my question includes a high-end projector maybe its fine here.
What's the difference between lens zoom and telephoto lens zoom?
In this Shootout (see below) it says that Panasonic AE7000 can light up a 120" 16:9 screen from a throw distance of roughly 12 to 23.5 feet.
I've got 12 feet lens to screen.
And this is what confuse me, it also says that AE7000 loses up to 42% of its light output when the lens is set to maximum telephoto. And that I should avoid doing that.
I must max-zoom to fill a 120" from 12 feet. Does that mean I'll lose 42% brightness?
