Since we seem to have crossed over into talking about the 3.5
Altman's, I'll
throw in my little
bit of knowledge about them. Over the years, I bought about 18 of them from
Altman's rental
house. They are great little instruments, which also have the ability to use different
focal length lens tubes in the
base unit. As for the
dichroic reflectors, they did produce a few with a polished faceted
reflector, which I am sure cost them additional $$$'s. I was told that they got complaints that the increased light output was eating up the
color media. I have 7 of those and wouldn't trade them for almost anything. The light output using a 575watt lamp is quite impressive. The only brown
Altman's we still have are some 'older' (LOL)
360Q - 20X40 zooms. I'll bet you don't see them very often, if ever.
