I am now confused by the specs on the RS65 which I plan on getting shortly. I am told that you can get the 2:35:1 image ratio without the anamorphic lens but that you have to do this through the zoom feature. I am also told that if you use the zoom feature to get 2.35:1 the picture is not as good as if you use an anamorphic lens.
Can anyone please shed some light on this.
Very much appreciated.
I have been asking the same in the other thread and after some good advice from HogPilot (who owns the RS55 + ISCO 3 Loves the combo) he recommends trying an A-Lens and see for yourself (Prismasonic gives a 2 week grace period).
Without seeing 1 in action so to speak the Zoomed RS65 235:1/117" wide Max zoom 13`7" throw i use now looks bright 208 Lux/sharp/6million e-shifted pixels/34000:1 on/off.
if i added an A-Lens the numbers would be roundabout 50 Lux brighter 25%/no overspill/mid zoom so greater contrast 38000 on/off /less sharp maybe/2 million more pixel fill.
It sure looks on paper you don`t get much for the outlay. 50 Lux/4000 on/off-/2 million more pixel fill (this could be the main visual reason to install an A-Lens) /sharpness may suffer.
Screen 117x50=41 Sqft Lamp 106 hours old.
Projector Lumens = (lux*SqFt)/10.76 208*41=8528/10.76=793 Lumens * 1.2gain = 951 Screen Lumens
Calculate for 258 Lux = 1179 Screen Lumens vs 951
With A-lens i would gain 230 screen Lumens 1179 Lumens 3m screen. 35 footlamberts NOT calibrated
