SIMPLE STANDARD/REGULAR 8 QUESTION

[Lunar07]

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.

As I mentioned this is not the issue, I leave that to the user to decide. But a photographer should at least quote the designations correctly and be aware of the difference. In general, it pays to be able to know the CORRECT designations of at least the 85, 80, 81, 82, G, R, X, O, and ND series of filters and what they stand for.

...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.

Can you proof this?
All I can find on the web are lists like this one (http://www.adorama.com):

• "85" series are color conversion filters for the use of tungsten type color films in daylight.
• 85(85A) decreases the color temperature from 5500°K to 3400°K for the use of Type A tungsten film.
• 85B decreases the color temperature from 5500°K to 3200°K for the use of Type B tungsten film.
• 85C decreases the color temperature from 5500°K to 3800°K. It adds daylight warm to indoor shots using window or natural light.

Quotes like this one (super8-meta-directory):
"Most Super 8mm cameras have a builtin Type A filter or Wratten 85(also known as Wratten 85A)"
And several companies that either only produce a "Wratten 85"-filter (without any letter) or all kind of 85er filters with letters (85a, 85b, 85c, 85ef, ...) but none without a letter!

The only source that indeed lists a difference between a "85" and a "85A" is http://www.bhphotovideo.com:
85 SERIES COLOR CONVERSION CHART
An 85 decreases the color temperature from 5500-3400 degrees Kelvin
An 85A decreases the color temperature from 5500-3100 degrees Kelvin
An 85B decreases the color temperature from 5500-3200 degrees Kelvin
An 85C decreases the color temperature from 5500-3800 degrees Kelvin

In other words: If you compare two different webpages, you'll find at least three different interpretations whether a 85 is the same as a 85a or not...

All this tells you the amount of confusion out there - many have confused the desgination 85 Type A or 85 A (as appears on many Hoya old filters) with 85A. Many have got it down right wrong! Bhphotovideo got it right. Rest of them got it wrong. Because they can not read the designation correctly. Also, find two filters - one 85 and one 85A and see for yourself the difference. 85A is DEEPER amber than 85. How do I know? Because I have both B+W filters. By the way, the 85A filter is a VERY HARD filter to find. It is an old variation that dropped out of use. So many confuse 85 with 85A because the 85A is nowhere to be seen. The 85 filter is a standard easy to find filter.
For Cokin series, check:

Anyway, your ultimate source for the proof you want is "Using Filters" which is part of Kodak Workshop Series. By the way, I highly recommend this series. There you'll find all the information you need. In particular, 85 (the built-in filter in Super8 cameras for Type A films) is NOT 85A filter.

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... ;-)

Yes I have been so unlucky with those anamorphic setups :twisted: I was even so unlucky to have found the THIRD and LAST C mount to D mount adapter. It took me more than a year to get the three.

Do you see it? :-D bwahahahahahahahahaha
At last, THREE C mount prime lenses on a D8 or H8 along with THREE small ISCO 1.5X anamorphots. How unlucky

[clivetobin]

These filters are the same color as the No. 85 filter, but also contain ND (neutral density) of .3, .6 and .9 (1, 2 and 3 stops) respectively.

So an ASA 64 tungsten film of 3400K color balance exposed in daylight through a No. 85 filter will be 40 ASA. Through the above three types however the ASA will be reduced to 20, 10 and 5 in order.

This might be useful if wanting to film at a wide aperture for selective focus, that is for throwing the background out of focus to concentrate the viewer's interest on the main subject, which ideally is in focus.

The added ND used to, at least, be also available in the 85B line of filters, as 85BN3, 85BN6 and 85BN9. I don't think I have a current catalog.

If only that miraculous claim could be true. There is barely enough room for three prime lenses on a D8. I cannot imagine there could possibly be enough room to mount three anamorphics in position simultaneously. Show me a picture and I will eat my words.

I am still waiting to receive the third C mount to D mount adapter in the mail. When I do, I'll post some pictures.
The H8 will easily take 3 C mount prime lenses along with the small ISCO 1.5X anamorphots. On the D8 it maybe another issue. The B8 would work out fine.
