I have a filmo with a mask viewfinder. I assume the settings are for
focal lengths in inches.

The settings are:
1,2,3,4,6,10

I guess 10 inches is for filming the enemy very far away so they can't
see you, and given the finder, you probably can't see them either. ;)


What I wonder about is wide angle lenses. 1 inch would be a standard
lens size right? I've seen people describe this as 20mm or 25mm, (I'm
not sure which it is) so what if you had a 10mm lens or something? How
will you frame your shots. It would seem strange that you couldn't use
wide angle lenses, I expected to see 0.5 inch on there at least.

Can I just frame with the 1 inch finder setting for smaller focal
lengths and work things out somehow? How will I know where the eyeline
is???

eeeeek! :(

love

Freya

fortunatly My filmo uses the little screw in finder lenses, so at least when you can't quite see what you are shooting you can be resonably sure you are at least in the right ballpark! With the shake that you can get with a 3 inch, I suspect a 10 inch would require setting the Camera in Concrete!

Anyway, a "Normal" lens is a one inch, which would be 25.4mm if converted directly. A 17mm is a common wide angle.

Thanks for your help Charles! At least we have cleared up the 1 inch thing!

Are there finder lenses for the later filmos for focal lengths like 17/16mm?

I'm a bit shocked there is no 0.5 inch setting at least on my filmo. I'd rather have that then a 10 inch setting. I've never even seen a 10 inch c mount lens! (200mm???!!!)

Perhaps I will just have to point it in the general direction of the action and hope I get lucky. I guess you can get away with that a bit more at wide angle but it does not make me feel happy.

Does anyone have any other kind of suggestion for a solution?

love

On my finder turret I have a 17mm, a 1 inch and a 2 inch.

I have also found a 3 inch and a 6 inch. Although the old 6 Inch lens I also got off e-bay (an Egleet) needs to be taken apart and re-lubricated as I can barly turn the focus ring.

From one manual for a 200 series (which takes the same lenses and finders) they had a finder for each "official" B&H lens.

As far as your Camera, I wonder if the 17mm was developed later. The Flange depth (lens flange to film plane) on a C mount is something like 0.65 inch if I recall. that is 16.5mm so it is likly that the wide angle would have had to be a "real" wide angle, where the lens to film distance is larger than the focal lenght.

My other play camera is an old Keystone. That is only set up for a 1 inch and a 3 inch. and the finder is so small that you basicaly have to use the rectangle for the 3 inch as a cross hair to aim.
