norpus Posted April 19, 2007 Posted April 19, 2007 That will make those waiting for the JVC happy yep, I'm happy and will hopefully be more than happy tomorrow when the b.... arrives
The_Preacher1973 Posted April 19, 2007 Posted April 19, 2007 yep, I'm happy and will hopefully be more than happy tomorrow when the b.... arrives And you think you're tired today. Could be a big weekend.
Maverick Posted April 19, 2007 Posted April 19, 2007 Interesting to see that both Epson and Panasonic are offering 3 year warranties on their PJs. Mind you Panasonic need to have a drastic rethink on their customer service issues.
XR6T4ME Posted April 19, 2007 Posted April 19, 2007 I think you will find most of the projectors sold in US have a 3 years warranty whereas in Aust they are mostly 2 years.
mejutty Posted April 19, 2007 Posted April 19, 2007 A little bit off topic but it was in the article. "Brightness is a very ample 500 lumens with the zoom lens set to wide angle. However, it loses 45% of its brightness at maximum telephoto. Caution should be used in designing the layout. The AE1000 will easily illuminate a 120" screen from 12 feet, but not from 24 feet. " The way I ready this is that I should put the projector as close as I can to the screen and zoom out the lense to fill the screen as apposed to putting it back as far as you can and then shrinking the image to fit the screen. This confuses me, I mounted my HS50 at the back of the room, and basicaly at this distance the picture I throw is the smallest it can be moving the zoom only makes the image bigger. But going by what is said in the statement above that I should have made the image as big as possible then moved the projector closer to the screen till I got the desired size because this gives a brighter picture. Can anyone help me out with some understanding on this one.

If you place a projector with a variable zoom lens closer to the screen it will produce more light than if you move it further back and use the zoom to still fit the same size screen. This is because when the projector is further back the lens is only letting light through a much smaller aperture. As such, the amount of light passing through the lens is reduced. Therefore if you want a brighter picture, you should mount the projector as close to the screen as you can. Try and avoid the last 5% of zoom though as a lot of optics go off when used at their extremes.

Yes. although despite loss of some lumens, contrast is often improved and light scttered to the sidewalls (reflections) is also improved when the pj is throwing from its max distance (min zoom). Pick your poison.

Pick your poison. By shooting at the telephoto end you also reduce chromatic aberation and other lens anomolies by a significant margin. In general the long end of the lens is always better with the light trade off.
