I.ve been reading the postings regarding "banding" on the rotational lens
cameras, and hope I have some value to add.

I use a 1970 Horozont. Built from all steel etc and very basic. When first
purchased made terrible pictures because of banding. I'm not satisfied so,
like good "Kiwi" stripped it completely to figure out just what makes it
work. I've done this a number of times now and it will be a regular part og
my camera maitenance regime, because there are a couple of "tips" to make (I
think) any of these type of cameras work smoothly.

1. CLEAN CLEAN CLEAN!!!!! You simply must keep these things away from dust
and hair. I keep mine in a sealed plastic bag inside my regular camera case.

2. The secret to smooth rotation is "Torque" and "Loading". If you are
overhauling one of these cameras send me a direct email and I'll give you
the low down rather than take up heaps of space here.

I regularly take photos with my baby and even wide open on the slowest
speeds get no banding with clear blue skies taking over 50% of the picture.

Also for that horozontal flare that often occurs I "cured" that by doing
away with the fancy looks the manufacturers give the camera. Take a good
look at the outside of the body around the lens area. Do you see any
polished alloy or stainless edges especially on the lens housing or the
edges of the camera body just where the housing rotates. If you have then
get some "FLAT BLACK BLACKBOARD PAINT" just a tiny tin, and carefully paint
out those edges. You will be surprised at the difference this will make.

Be aware also just where is the sun when you use the camera. They do not
handle back lighting of the subject at all well. Good luck, have a great
festive season if it applies, and catch up with you all next century eh?

Cheers Julian.
