P. Funk Posted January 29, 2004 Share Posted January 29, 2004 5° source 4 fixed focus would be ideal. just very very heavy. cantata with an iris would be very inefficient, as you would not get that much light output (60% or whatever the iris was would be lost) - inverse square rule etc.. all common sense.

Stu Posted January 29, 2004 Share Posted January 29, 2004 Again, crap optics. Source Four's also really don't like Iris', I think it's near damn impossible to maintain a nice focus when one is it. I personally recommend looking at a Strand SL 15/32 with an Iris, or perhaps an Alto 8/16 (with possible Iris?). Stu Link to comment Share on other sites More sharing options...
misterbassman Posted January 29, 2004 Author Share Posted January 29, 2004 ok thanks guys I will look into these, Im not sure about iris, because Ideally the beam needs to have very sharp edges. Link to comment Share on other sites More sharing options...
NickGale Posted January 30, 2004 Share Posted January 30, 2004 Try the Selecon Pacific range - the 5.5 - 13 degree zoom will do exactly what you want - actually it's 0.77m beam at 8m, so you may need an Iris. Unlike the competition it will stay sharp with an Iris (or gobo!)

Tomo Posted February 1, 2004 Share Posted February 1, 2004 I'd go with either the Pacific or a Source4 5 degree. The Source4 weighs around 8kg, which is pretty light compared to your suggested Cantata (about 13kg). The thing to remember is that they have very big noses, so physical space might be limiting.Having just finished a run of JCS where I used Source4 10 degree and Cantata 11/26s, the quality of the Source4 beam is so much nicer as well.(Gethsemane was superb, but then I would say that) I haven't used Pacifics as they appear to have limited availablility up north, but I understand that they have pretty nice optics. If the exact pool size isn't important - ie you just want "Smaller than this, bigger than that", go with a Source4 with the right lens tube on as it's quicker to focus, and lighter than a zoom.If you really want your pool to be exactly 70cm in diameter and properly circular then get a zoom, such as the Pacific. And I really should go to bed, as I've got the getout in 8 hours. Link to comment Share on other sites More sharing options...
