SIMPLE STANDARD/REGULAR 8 QUESTION

[Esoteric]

Hi everyone,

I have been using Regular/Standard/Double 8 in my Sankyo Auto 5X for more years than I care to remember, with 25 ASA daylight film. Naturally, I set the ASA setting on the camera to 25 ASA too. No problems.

However, I have just acquired a stock of 40 ASA tungsten cinechrome film, which requires the filter to be in place for daylight shooting; and without the filter for indoor/tungsten lighting shooting.

My silly question is what setting should I put the camera's ASA dial on :?:

Should it be on 40 ASA for indoors without the filter, and 25 ASA for daylight with the filter, or do I leave it on 40 ASA for both? :? :oops:

Many thanks in advance for your help.

Dave.

Yes it's 25 ASA for outdoors with 85A filter and 40 indoors with tungsten lights.

85B filter

... depending on your filmstock, you'll have to use a "85A filter" (AKA "85 filter" <- note the missing letter ;) ) instead of a "85B" one!

Yes, my mistake I was thinking of something else.

Cheers!

Yes. Thanks chaps. It is an 85A type filter which is built into the camera and is swung in and out of position by means of a thumbwheel on the side of the camera.

I had deduced that this was what was meant, as I couldn't see the point of the camera manufacturer installing an incorrect filter.

Thanks again,

Dave.

If your camera has "through the lens metering" then set ASA to 40. The camera meter will compensate for the filter. If the camera does not have TTL then it is 40 without filter and 25 with filter.

Hi John,

No, this particular camera does not have TTL metering, so manual adjustment is "the order of the day".

Cheers,

Dave.

The problem is that the camera manufacturer hasn't got any clue about your actual filmstock and most likely didn't even know all filmstocks that have been available when the camera got produced decades ago! Hence he can't be correct except by chance!

E.g. nearly every Super8-camera comes with an integrated Wratten85A-filter which was good for the Kodachrome 40, ... (endless list of all tungsten-balanced super8-films), but the new Ektachrome 64T will require a Wratten85B!
Here's the 64T with the "Filter No. 85B"-hint:

And here's the K40 with the "Type A"-hint:


In other words: It wouldn't harm checking the data of your filmstock!

P.S.: There's even a 85N3, a 85N6, a 85N9 and a 85C in Kodak's list of "Amber series of conversion filters for color films", but I haven't seen any "motion picture film" for 8/9.5/16mm that doesn't use a 85A or 85B.

Unless, of course, the camera automatically compensates when you switch in the filter.

the filter that is built into Super8 cameras is 85 NOT 85A. This has been noted so many times before. The filter is 85 FOR Type A films. 85A is a different filter altogether.
With K40 you use 85 filter (for Type A films),
With 64T you use 85B filter.

85A is another color correction filter that does not apply to K40 or 64T films.

Oy Lunar, if you only had a nickel for every time you've clarified this point. 85 versus 85B versus 85A will be your legacy on this forum. Unlucky you, it should be those fancy anamorphic setups... ;-)

How big difference is it between the 85 and the 85A filter? :?:

[S8 Booster]

not sure abt the 85A but here are some impressions of the 85, 85B, 85C etc

The list you give states the 5500-3400 conversion of the 85 filter. 3400K is the tungsten balanced Type A films like the K40.

The 85A is for 5500-3100 conversion. Very much close to 85B (5500-3200).
This answers Upsalla's question.

Of course the issue here is not whether you can use 85A filter instead of 85 filter and achieve the same results. I leave this to the users. But this is just a statement of fact on the type of built-in filters used in Super8 cameras. source of confusion is that many 85 filters have the designation ( 85 A ) or (85 Type A ). This is often confused with 85A. 85A is one thing. 85 A or 85 Type A means another thing: 85 filter to be used with Type A film. Not the same as 85A.

For that small difference I guess it really doesen´t matter, at least not if you plan to edit in NLE, you can just adjust it in post.
