    Hi,
    I have an upside-down Epson EMP-TW10H on a high-ish shelf level with the top of the image; very easy as it came with 3 rubber sticky pads you attach to the top surface of the PJ.
    Do any Z3 owners know if their PJ has the same option. Would a DIY sticky pad option a la my Epson work??

    cheers
    Dave

    as i understand it, since the lens shift on the Z3 is symmetrical and the neutral position of the lens is along the lens axis, mounting the Z3 upside down wouldn't be any different than mounting it the right way up.

    e.g. if you mounted the Z3 upside down and required 20% lens shift in the projectors "up" direction, you could just as eaily mount it the right way up and use 20% lens shift in the projectors "down" direction.

    unless you have another reason to mount it upside down...

    Thanks Paul... could someone confirm that the Z3 thows the image centrally and not (assuming PJ the right way up) bottom of image horizontally and the top of image up - as i had presumed...

    many thanks
    Dave

    Hi

    The lens shift on the Z3 is completely symmetrical.

    At one extreme, the bottom of the image is level with the lens. At the other extreme, the top of the image is level with the lens. With the shift in the middle, the centre of the image is in line with the centre of the lens.

    Regards,

    Steve

    Hi

    Are you sure it will need to be upside-down?

    The lens shift is probably adequate enough for you to leave the projector the right way up on the shelf.

    All the Sanyo Z series projectors have 3 x M5 threaded inserts in the base so they are easy enough to bolt upside down.

    Did I read your post correctly - you have *stuck* your Epson to the shelf with sticky pads? No bolts?

    Digger - if what Steve and Monopole have posted is accurate then your original post has already been answered - you put the projector on the shelf the right way up as it makes no odds to the picture/throw and will mean you can press the buttons without having a shelf in the way!!! If you really wanted to you can still put it on pads, it doesn't come with any though.

    I was wondering exactly the same thing! No way would I trust double sided sticky for that job.

    sorry guys...sudden loss of brain function on my part!?! My upside-down Epson came with a set of three rubber pads that you attach to the top of the PJ if you are installing it high up on a shelf (saves cost of a mount) so as to throw the image with the correct orientation at objecively "correct" height. Sorry Stevelup, obviously you wouldnt need to invert a Z3 now would you... :blush:
    Only asking these questions to work out whether to upgrade to a Z3 or similar.
    thanks for the replies
    cheers
    Dave

    Indeed, the Z3 will definitely be OK the right way up - no need to flip it.

    Although as eveyone says, with the Z3 there is no difference.

    Normally on a ceiling mount it is better upside down as that means all the controls on the top of the projector are accessable to you when you look up, rather than having to get a ladder out to look at the top of it near the ceiling.
    (if you loose the remote control)
