    Anyone know if there is a calculator will will give a list of suitable projectors for a set screen size at a given distance.
    I want to celing mount but am restricted to a location which will be approx 3.2Mt from the screen which will be a 166cm diagonal.
    I am looking for a LCD PJ to suit. I know the Panny PT-AE700 will do it but I'm a little concerned re the VB issues I've read about.

    Yes I have. I am leaning towards the Z3 but the calculator shows a minimum picture diag of 203cm at 3.2Mt.
    I am hoping to get away from having to wheel out the pj everytime I want to watch a film and having to fine tune the size and focus because it's never in exactly the same place twice.

    Just discovered. If you click on "find projector" at projectorcentral.com you get the option to input your required screen size and distance. Have done so and got four results.

    Unfortunatly the only realistic one is the Panny. I'll look into the lens option you mention Horny, cheer's.

    I hear what your saying. As there is nowhere near me to demo I can only go on users opinions and I must agree that they does seem to be a large majority of people who own the Panny and sing it's praise's and don't have problems with VB. Only trouble is those that do mention it say it is bad.

    Horny, just got a reply from AV Sales. You cannot do anything re the lens on the Sanyo. They are also not sure the Panny will suit either. Have check the calculator again and that lists the model number with a "u" at the end, don't know if it's different from the european one.

    The panny does have a long throw lens on it. I nearly swapped my Z3 for the panny as I needed a longer throw.
    I decided to keep the Z3 and work around it as the picture is awesome once set up correctly.

    If I'm going for the Z3 I'm going to have do some rethinking. the calculator shows around 2.4 - 2.6 Mt for a 166 diag. Just wondering about some sort of wall mount that lays flush against the wall when not in use but can be swung out as required.
    The bracket would be the easy part. Selling it to the wife as essential will be the dangerous bit.

    this may help
    consider the width of the screen instead of the diagonal size - it's much easier

    it's fairly easy to do with out a fancy calculation website - not so easy to get hold of when you're on site or at a gig
    on 4x3 screens
    on a 2:1 lense the throw is double the screen width
    on 1:1 lense the throw is the screen width
    and so on
    on 16x9 screens it's different i tend to work out ratios with maths


    also if you're looking for a cheap beamer with a wide angle lense Sharp do a 1400 lumens model with a 1:1 lense and 4 way lense shift for about £5-600
