I’m considering a Stewart screen with drop down vertical masks that only allow for 1.78 or 2.35 aspects - rather than a Vistascope with variable masking (and tweaking aspect ratios). So I’m wondering if aspects will still be true with the lens in place as there’s no tweaking the masks with this screen.
ALSO, can the Sony 5000 crop 1.85 to fill a 1.78 space? I’m not planning on a Lumagen (yet).
I have found no need to play with the vertical masks - i might be losing/gaining picture width but it is so minuscule that I don't notice it.
I can attest that if I walk up to the screen a foot away - I can see slight fringing on the last box and certainly on the perimeter all around but if I step back say 4 to 5 feet my old eyes cannot see any fringing.
There is minor minor minor barrel distortion in the internal pattern but it is like splitting hair - cannot see it in the movies.
Interesting .... planning a screen to work around the DCR fixed lens - you are a brave person - what happens when two yers later a projector shows up which is 10,000 lumens and can do AR control/processing?
The screen is the longest lasting piece of the Theater IMHO - even the screen material can be changed.
About blanking - I had my first annoying experience with he DCR last week watching 'Shape Of Water' which is a 2:35 movie expanded to 2:40 - the subtitles when the characters speak Russian were cut into half .... (half on the screen and half on the black velvet)... no way around it...
Shawn could answer on the Sony's capability to crop.
My two cents - the picture with the DCR is awesome - brightness improved most importantly I love the resolution bump and the ease of use.... if one wants perfect internal patterns and uses a magnifying glass you will find issues even at perfect throw like mine.
Lumagen - I don't and will not be using the Lumagen - will steer away from the pack on this one.
