as i like to know and some ask for it i measure like above but iris manual max.
close and i found
18700:1 cr.
the light out was reduce by 54% in this mode cr. increase was 73%.
that is may for some nice with smaller screens and for people not like the adaptive iris.
again my numbers are always a bit low compare to other that measure
cr. numbers.
i try first time 3d and a first short test looks very promising.
very little ghosting and the pr. profits from the 2000 lumen light out.
so my summary is till so far.
a very good pr. that delivers around 2000 lumen at d 65 with a cr.
native at over in the 11.000:1 range.
i like the reality creation a lot but sony should allow even lower
resolution and noise reduction inside this function.
this pr. set a new standard for sure and from this day on 4k resolution is a must for high end pr.
Very interesting, and thanks esp for the closed iris measurement.
I note an interesting comparison to the RS55: at D65, max zoom, HI lamp, with iris open (to generate its max calibrated lumens), cine4home reported 920 lumens and CR = 26000:1. W.Mayer's report for the 1000 (at D65, max zoom, iris CLOSED) values of ~1100 lumens and CR ~ 18700:1 (or maybe higher as he notes he often measures low CR).
So, the two give approximately the same native CR if set to give approximately the same lumen output. The Sony of course has a good DI to add onto this, and also the possibility of >2x the lumen output still with very good native CR.
