It looks like my high school's theater department is finally willing to replace at least a few of our dozen ancient Altman 360's with some Source Fours. I'm debating whether I should get the standard Source Four or the Junior model, though. I've done some searching on this forum, and it's (not surprisingly) universally agreed that the standard model is far superior to the Junior. However, some of the drawbacks don't apply as much in my case; for example, I use 575 W lamps in my current ellipsoidals anyway, and my throw from my off-stage lighting bars is within forty feet anyway. Aolso, one of my main gripe about the Altmans is that their lenses have terrible chromatic aberration, since I always get a fuzzy blue/green ring around the edge of my focused beam. Junior lenses aren't supposed to be as good as the standard lenses, but are they still a significant improvement over the Altmans? To summarize: should I just get some Juniors or splurge and get the standard fixtures?
