Re: Anamorphic Projection Theaters

i keep seeing these pics and wanting to go with 2.4 setup over 16.9. can't decide, especially if projector doesn't have a memory lens.

Re: Anamorphic Projection Theaters

If the projector you have or are looking to buy doesn't have auto AR, then an anamorphic lens is a good alternative to manually zooming for the different aspect ratio's..

Re: Anamorphic Projection Theaters

i've heard those are pretty expensive. as far as manually zooming, what exactly does that involve. would i be simply adjusting the lens by turning it somehow. just curious the amount of work that would be needed when someone talks about manually adjusting

Re: Anamorphic Projection Theaters

When you manually change AR's, you would select 2.35 on your remote ( if you're changing from 16:9) and manually zoom the image to fill the screen..and sometimes you may need to refocus..and it's not always easy to just fill the screen and not lose some of the outer image onto the borders..
Generally it's a pain..and particularly if you need to change from 16:9 to 2.35 and back to 16:9 AR during a movie night..

There are more and more projector makes that are now including auto AR's..My last projector has that facility and I'm now able to do away with the anamorphic lens..

On my projection system, it takes less than 30 seconds to adjust between aspect ratios. That includes adjusting the zoom control ring, vertical lens shift knob, and moving the drapes for masking. Focus is stable when zooming on my projector.

Vertical lens shift range will vary, depending on projector placement. None at all is needed if the lens is located perpendicular to the vertical center of the screen.

The wall behind the screen should be painted black or very dark. Black bars on letter boxed Blu-ray Disc movies will project onto the wall above and below the screen, which can be distracting if the black levels on the projector are not good enough.

The lower cost JVC D-ILA projector model still has excellent blacks, plenty of motorized zoom and shift range, plus lens memories. Last I checked, the less expensive Panasonic LCD projector is similarly enabled. The Epson line may also include a candidate.
