Is this normal?
I feel thicker in colors than before.
Is this from firmware updating(8.101 to 8.102) or due to iris movements?
You may have an intermittent iris issue, in which case it could have been prudent to hold out for a replacement lens. See how it goes as it may wear itself in so-to-speak.
Where you are based?
As for the colours, when you say 'thicker' do you mean deeper?
The iris is just limiting the amount of light hitting the screen and hence giving deeper blacks (especially in light controlled environments). It is doing it in concert with a dynamic light source (which is doing the lions share of the dimming) and that is why it doesn't need to be super aggressive and this results in zero (that I have noticed) artefacts such as pumping.
I have to say it is more effective than I thought it would be and I thank Sony for giving my projector new legs and not just leaving us behind with a new model with these features.
Watched the Blu-ray of Riddick the other night (the directors cut that, incidentally, has Katee Sackhoff showing a little more than I expected...
) and pausing the image on a dark scene (plenty of them in this movie) showed the dimming and iris to make a superb level of difference to the perceived black level. I was happy before, but now I am delighted.
The cost of these devices has reached a point where people are buying them only after MUCH financial consideration and as a result will not be intending to buy again for a considerable period of time. So support is necessary to make sure customers feel like the company actually appreciates the choice that has been made and are not just considered as wallets.
Most cannot afford to simply supply a second hand market with projectors just to get a new model with a feature the old model could support with a simple software update.
Keeping current inventory going longer is a more environmentally sustainable model and one I support.
Now if only the AVR market would wake up to that as well!
