Re: Are D-mount lenses too small for super 8?

For example, the film gate of all bolex H8 double 8 cameras , non reflex(D mount) and reflex models("special" C mount), are not on the centre of the lens mount. It shares the same position as DS8 version of H8 reflex, and the non reflex H8 has the same design even it had never had DS 8 version. The...

Re: Are D-mount lenses too small for super 8?

I think D-mount lenses were made primarily for the regular 8mm format, so their flange focal distance is 12.29mm and not the 17.52mm common to Super 8 cameras accepting interchangeable lenses. There are C-mount to D-mount adapters, but not the other way around.

It is not the end of Bolex camera or such.
This was meant tongue-in-cheek. It's obvious that it isn't a product of Bolex International S.A.

Re: Schneider Kreuznach Optivaron filters

Sciolist, have you noticed that in addition to put filters in the filter holder and with screw directly on the lens (vignetting risk) can be screwed in FRONT of the filter holder? Serve 77mm diameter filters, I already have some of Krasnogork 3 of that size, I might try this method. What do you thi...

Re: Moviola help

My question is the sprockets seem to be on the wrong side so the emulsion is running up...is that correct? The M-50 viewer, which is a component of the M-79, was made in at least three versions; maybe the M-79, which is also known as the Moviola Junior , was as well. The M-50 was configured for fil...

Re: Schneider Kreuznach Optivaron filters

I've fit 72mm filters into the lens hood compartment designed to accommodate series 8.5 filters. The front filter attachment size of the lens is 62mm, but it's best to use the compartment in the lens hood because of the risk of vignetting when that lens hood is attached to a filter.

A lubricant I've found useful in many applications is Teflon grease.

Re: Angle for Bolex

I've got right-angle optical viewfinders made by Minolta (one is branded Minolta and the other ALPA) that attach to the Bolex H8 RX4 10x viewfinder eyepiece. Of the same kind as those used with 35mm SLR cameras (and the Leicina Special ), they've each got a collar with three setscrews to hold them t...

Re: Does anyone here glue magnetic tape to films?

Nice! Forgot to ask. If you have about 400 feet of film before striping (according to the measurement provided on the takeup reel) how much more will it measure since it becomes thicker after striping? 500? I’ve run a sound-striped film through a Super 8 synchronizer + footage counter and, e...

Re: Does anyone here glue magnetic tape to films?

Oh!.. Hmmmmm. Only one side and no balance stripe? Sounds like that could a problem? How does it roll up onto the reel? I guess one side of the film gets pushed closer to the lens than the other. What do you do? Correct it by turning the screen at an angle when you play that film? A lot of folks se...

Re: Does anyone here glue magnetic tape to films?

I know what you mean, you edited out some of it. So did you put on 2 soundtracks? Or a soundtrack and a balance stripe? Did you put on one at a time or both at the same time? The Weberling striper I used in the 1970s could only apply the main stripe (I've still got two of these stripers). I've also...

Re: Does anyone here glue magnetic tape to films?

So you spliced together about 16 cartridges worth for an 800 footer, then striped it all in one session? Guess you used a cement splicer? Any problems at the spliced joint where the films overlap? Well, it was more than sixteen cartridges, but the end result fit on an 800-foot reel. The capacity of...
