This was sent to me as an Email any one want to have a go before me?
will try this.
the solid aluminium lenses are the predecessors of the hd8 b hybrids, featuring all glass lenses.
the hybrids have a glass/acrylic lens mixture, resulting in better edge focus. whereas the heavyweighted ones reveal a little more resolution, but just a little. the main advantage is their better themostability. when running high resolutions, there´s less lens focus drift.
roland, have i forgotten something?
Well just the fact that 801s blows the cooling air out through around the lenses(opposit 800)and therefore its not that stable in mechanical focus during the first 20 minutes.You could be better off with the aluminum lenses!
There is a third lens type that is MEGA Rare and I consider the best of both worlds......
Its an Aliminium cased HD8 revB
better thermal stability and focus - what more could a Barco guy wish for - these were the run off of the old housings with new lens internals - how do I know this, I have ONE with a HD8 sticker with the Reb B sticker over it
PS - Sorry if the look of a post by Roland shocked you all
