Regarding sharpness and overall image:
It is no getting around it. I prefer to get right to the point: the new VW500 is not so far from VW1000 as you might infer from the declared characteristics. The luminous flux, net of calibration, it is very, very close to that of the VW1000. Spannometricamente, considering the gain of the screen I've seen and measurement to the white flight that I was able to do, (never leave home without a photometer!) The projector is brighter dell'HW50. So I expect at least 1,400 lumens and maybe even 1,500, so that the 4 meters wide with a unity gain screen will absolutely not be a problem either with lamp in economy mode.
Even the 'objective has impressed me. The time available (very little) and the absence of test signals (next time, in addition to the photometer, I must remember to bring those too!) Did not allow me to make sure references but I still found the image very well, and very close to that of the VW1000. Probably - this is a must for confirmation - compared to VW1000 is perhaps a bit 'less accuracy in the outlying areas. I thought it was rather good uniformity of the luminous flux.
What does luminous flux mean????
