Sony VPL-VW95ES Projector - Performance

That translates into a roughly 25% drop in brightness going from the closest placement to the furthest placement allowed by the 1.6:1 zoom lens. Closest position is only about 8% brighter than mid-point, while furthest position is almost 20% less bright than mid-point.

Lumen Output (Low Lamp, Dynamic mode):  497

That works out to a surpisingly large drop of 42%. Most projectors drop 20 - 30% when switched into low lamp mode.

Below: sample color temperature snapshot, pre-calibration - not quite as good as last year's projector, as default is a bit too cool.

Interestingly, the various iris settings of the Sony projector do affect measured output. For example, the projector is almost 10% brighter with the iris turned off or on Auto modes (dynamic) than when in manual use:

As you can see, in manual mode, the maximum you can close it down is 50% in terms of brightness.

That should give you a pretty good idea of the relevant settings and how they affect the projector's picture.
