Tests on Agfa Aviphot Pan 80 and 200 films

[georgegrosu]

Tests on Agfa Aviphot Pan 200 and 80 films.
In test 405 Agfa Aviphot Pan 200 I exposed in wedge (250, 160, 400 and 640 ISO) and scanned as a single photogram.

The resolution on the Aviphot Pan 80 image is impressive, but the contrast is rather high.

Thanks for these pictures. It suggests to me that each film has about the stated box speed. I get confused about the connection if any with Rollei films but there appears to be a suggestion that both Rollei 80 and 400 are in effect the same film and both are Aviphot 200 or maybe the suggestion is that Rollei 80 is Aviphot Pan 80 and Rollei 400 is Aviphot 200.

The latter explanation may be possible as if they are based on Aviphot Pan films then Rollei 80 and 400 are not the same film based on your tests. If Aviphot 200 is Rollei 400 then it certainly looks as if you could claim a 400 speed and I for one would probably not challenge you.

Yes you are right : Resolution of Aviphot Pan 80 has to be impressive.
Because it is designed for.
And from massive orders of great volume in the past Agfa Leverkusen make some veritable profits.
Notice : In military air reconnaissance there is no way to ask for the costs of a emulsion.You have the costs in flight hours.
So there is only a way to ask about :
RESOLUTION !
It is a quite good film if it is fresh.
By the time what is the production date -
do you find any markings with numbers?
And what is your result in concern of grain with Pan 80 / also known as Retro80s ?

Rollei Retropan200 should be the candidate if you compare with Aviphot 200.Just have a look to the IR characteristic courves on both films.

The films used are Agfa Aviphot Pan 200 and Agfa Aviphot Pan 80.

These films are received from an Agfa representative, in 2010.
I want to thank Agfa for these films boxes.
These black and white negatives do not have key code (perforation markings).
Films have only the label on each box.

Well George - as we know some totaly new produced films in bw has expired dates of Full 3 years just from now.
(have a look to brand new Ilford films).
And we also know this : Some tolerances to bw films may concern some bw films in a way we can use them much later than an expired date showes.
A min. of 1 year should be absolute realistic. (with very strong pretentiously
intentions ).
Mostly it is a longer period bw is rated as
"good" after expiring date.
So you are quite glad to own "nearly fresh aviphot" if it was stored the best way.
Thanks for this Info again
with regards

In cine films you will never find an expiry date on the film box.
Write the film data (emulsion number / roll number) to the filmmaker, and he answers if it expires or the date until he has the warranty term.

Yes I know George - with Kodak you just have your Key Code.
So Agfa managed AVIPHOT so as other
manufactuer with Cinefilm do - well I just would like to own a big cadrigde of
AViphot Pan80.
Like this here from Kodak :

Key code is required only if you mount a negative recorded.
If you use the film for photo to load cassettes, the key code would help you see if you developed well (orientation).

Hi Nokton48 ...
Yes that is the right stuff at all. But it is sade to notice air reconnaisance ended last decade on film.
At the end a lot of this stuff wich have no need to use were produced.
I speculated the main bw films Rollei intruduced from aviphot resouces came from such sources.
For example from inventories of Tactical Air Force Wing 51 "Immelmann" :

They served air reconnaissance with this
special stuff :

"GAF (German Air Force) Telelens Pod"
with a special ZEISS Oberochen Film Camera look at this pretty baby here :

Data:
610mm/f4 - f16
240mm x 152m (film type)
115mm x 230mm (frame format)
1200 frames per film
4 frames /sec. max speed
1/2000 - 1/150sec. exposure speed.

And just from this little info one can imagine that ALL aviphot films from AGFA
Leverkusen has to have the posible highest standard in characteristics you would have an urgend need from air reconnaissance :
1) Resolution
2) Resolution
3) Resolution. ...

AND IR Abilitis.
