Optoma HD8600 Physical Tour-4

DLA-HD8600 Lens Shift

The HD8600 has a decent amount of lens shift. It is set up unequally, which is always interesting to consider. I found the manual very confusing. Here's how it seems to work, first for shelf mounting. For shelf (or table) placement, it can be anywhere from 10% of a screen height (4.9 inches) below the bottom of the screen, to 30% (14.9 inches) below the top of the screen surface. A 100" diagonal screen is about 49 inches high. That's measured from center of the lens.

For ceiling mounting, where you often prefer the projector to be above the screen, the HD8600, (inverted) in a ceiling mount can be from 10% (4.9 inches) above the top of the screen surface, down to 30% (14.9 inches) above the bottom.

I think that by doing it this way, Optoma has pretty much gotten the best combination of functionality relative to the amount of total lens shift they were comfortable providing in this design. The fact that there are other lens options may have encouraged this final setup, as well.

HD8600 Anamorphic Lens Support

The Optoma HD8600 has support for an anamorphic lens and sled. Optoma packages an anamorphic lens it sells to its dealers.
