Oh, I almost forgot. As all remaining stock of Orwopan 400 (HP 5 at a low-budget price) has sold out and the price of the UP 400 (another rebranded HP 5) has gone up, we are launching a more affordable version of the HP 5 for our customers: the ADOX CGM400PRO.
Until then, we’ll continue to sell the UP400 at the old price so there isn’t a ‘gap’.

Hello,
If it’s going to be called ADOX anyway, why not just call it ‘ADOX KB 27’ like it used to be? That was actually a real product back in the early sixties.
Otherwise, it’s good to be able to get hold of an affordable HP 5.
Best regards,
Walter

Hi Walther,
Thanks for the tip.
We’d already thought of that – there are old film boxes lying on the desk – but it isn’t the old KB 27, after all...
It’s a different story with the 25 and 100, but the branding ‘is now standardised to ASA 5’ :) so 25-100-200-400.
The DIN standard is no longer relevant internationally, and we’d only confuse customers in neighbouring European countries.
Best regards,
Mirko

It’s not just foreign customers; younger ones too – like me – I always have to unpack the Gossen Beli and check the sensitivity dial whenever someone’s only specified DIN again... It’s just a matter of what you’ve grown up with...
Gast
Hello,
Converting DIN(X) to ASA (y) is easy!
y=10^((x-1)/10)
That was just a little joke – but it’s actually mathematically correct.
But of course I understand that not everyone is familiar with the DIN standard, and you don’t want to alienate your customers.
Best regards,

Hello!
ASA may be more commonly used, but since ASA ratings have become fashionable, the speeds are no longer accurate.
In the past, when 16, 17, 18 etc. DIN were printed on the packaging, that’s what was actually inside; the best example is the EFKE KB 50, which used to be called EFKE KB 17 (40 ASA) – I’m talking about EFKE here, not ADOX KB 17.
This just goes to show what people will do just to come up with this utterly daft sequence of 25-50-100-200 etc.; at least the DIN values were honest.
So it should really be called KB 20 and KB 40, but that’s probably less marketable.
Best regards,
Georg

>> The sensitivity of Efke 25 is 14 DIN (20 ASA, ISO 20/14? GOST 18)
That’s what it says on the fotokemika website.
>> Unlike all the other so-called ‘25s’ on the market, the KB 25 has a genuine 25 ASA
That’s what it says on the FOTOIMPEX website.
>> At least the DIN values were honest.
One can only agree!

Ferdinand,
Fotokemika doesn’t have a website.
See also my comment in the article on EMAKS and VARYCON. It’s a scam designed to fleece the company out of money.
Furthermore, if you’d quoted the whole thing, it would say: “Sensitivity of Efke 25 is 14 DIN (20 ASA, ISO 20/14 GOST 18), but by developing in compatible developers, Efke’s sensitivity can be increased by up to twofold to 100 ISO.”
Why do you always leave out the bits that don’t fit your narrative just to stir things up??
The speed of 25 ASA was, of course, reprinted by Fotokemika in the mid-90s, not by us.
We also enquired, and we were told at the time that, due to slight modifications in the formula when production was transferred to the casting plant in Samobor, it had been established that the effective speed of Efke was actually higher than had previously been stated.
The statement in the product description refers to the fact that all other manufacturers I am aware of still recommend significantly higher settings than is actually the case. This means another company would sell the efke 25 as a 50 (as Jessops in England does with the 100 efke, for example).
As customers using efke for the first time tended to overexpose by +1 straight away, as they were used to doing with their other films, for example, we had to include this clear warning. A single-layer emulsion like efke is extremely sensitive to overexposure.
On the other hand, it has high sharpness.
If you’d quoted the whole thing, it would read: ‘The KB 25 – unlike all other so-called 25s on the market – has a genuine 25 ASA and can easily be pushed up to 100 ASA. Even in standard-strength developers such as ID11, it rises to 18 DIN/50 ASA.’
And the catalogue states:
Please note: all Efke films have ‘true’ speed. This corresponds roughly to double the speed compared to the ISO of Western films!
Please do not exceed the exposure or overdevelop the ASA films under any circumstances, otherwise the grey tones will not be correct.
Conclusion: like any other film, the 25 has varying effective speed in different developers, but compared to the ratings of other films, efke performs very well in terms of its effective speed versus the stated value.
If we take ID11/D76 as the standard (and the global sales figures for these two developers speak for themselves), we could offer it as a 40-50 ASA film.
So what to do?
We have actually considered re-releasing the ADOX as KB14 – but: there are no cassettes worldwide coded to 14 DIN/20 ASA because this does not comply with any DX standard. This would render the film unusable in many cameras.
In view of the facts described above, I consider it entirely justifiable to continue offering the film as a 25 ASA film.
A third of a stop more or less......Anyone who walks around with a calibrated Gossen meter has their own zone system rating to hand anyway.
Walter: DIN and ASA values are coming to the ADOX boxes! After all, we are here in.....

Mirko,
I didn’t leave out the postscripts because they ‘didn’t fit the concept’, but because they contain even more nonsense, meaning the discussion would have become even more confusing.
But please:
What are “developers that work at normal or forced speeds”? Either normal or forced, but not both?
Which are the “other so-called 25s” on the market? I don’t know of any – apart from the MACO, and as we know, that comes from the same source. If you mean the TP: it has no ISO rating. As we know, APX25 is no longer on the market.
As for the “effective speed” of films from other manufacturers, one could discuss this endlessly. Just this much: to my knowledge, it has never been seriously disputed that ISO speed ratings are determined under scientific conditions. The chronic overexposure practised by fine-art photographers (and the resulting downplaying of “effective speed”) usually relates to contrast-reducing development techniques (“pulling”) and the use of developers that do not fully exploit the film’s speed (e.g. Perceptol). Andre Hinse writes, for example, that the Efke 25 – when tested correctly – has only 12 DIN! -> www.artgrey.de
Conclusion: It is nonsense to base a sensitivity comparison, on the one hand, on the downplayed fine-art-printler EIs (where the HP5 drops to 160 ASA) and, on the other hand, on the pushy developers used with the Efke 25. That is no comparison!
You shouldn’t always see it as “nit-picking” just because someone reads your catalogue carefully. That’s pure idiosyncrasy!
Regards
Ferdinand
PS: What’s all this ADOX nonsense about, anyway? Are there many people who have ever seen an original ADOX print or printed one themselves? NO ONE disputes that films have improved over the last 50 years – everywhere. Only with ADOX are we told that 50 years ago they were already developing material that meets today’s standards. Or does it have something to do with the fact that “miracles” are “in” at the moment (Miracle of Bern, etc., etc.)?
MirkoBoeddecker
Oh, Ferdinand......
"What are 'developers who work in a normal or aggressive manner'? Either normal or aggressive, but not both?"
Examples
Normal-boosting: ID 11
Strong-boosting: Microphen
Non-boosting: Perceptol
"Which are the 'other so-called 25s' on the market? I don’t know of any – apart from the MACO, and as we know, that comes from the same quarter. If you mean the TP: it doesn’t have an ISO rating. As we know, APX25 is no longer on the market."
Referred to APX. Admittedly, it’s soon to be obsolete.
"As for the 'effective speed' of films from other manufacturers, one could discuss this endlessly. Just this much: to my knowledge, it has never been seriously disputed that ISO sensitivity ratings are determined under scientific conditions."
Under the same "scientific conditions", the efke 25 ASA
Conclusion: It is nonsense to base the sensitivity comparison, on the one hand, on the downplayed fine-art-printing EI values (where the HP5 drops to 160 ASA) and, in the case of the efke 25, on the push-processing developers. That’s no comparison!”
True. I didn’t do that either. I think it’s nonsense to argue about a third of a stop at all. But you started it.
"You shouldn’t always see it as ‘picking holes’ either, especially if you read your catalogue carefully. That’s just pure idiosyncrasy!"
Then just write something positive about efke and FOTOIMPEX for once. Then I’ll stop. I promise.
"PS: What’s all this ADOX nonsense about, anyway? Are there many people who’ve ever seen an original ADOX print or printed one themselves? NO ONE disputes that films have improved over the last 50 years – everywhere. Only with ADOX are we supposed to have developed material 50 years ago that still meets today’s standards. Or does that have something to do with the fact that ‘miracles’ are ‘in’ at the moment (Miracle of Bern, etc., etc.)?"
Where on earth did you get that from? I, for one, have never used the phrase ‘today’s standards’ in such a context. And everyone should decide for themselves what is better or worse. We offer
alternatives to modern films. With material that possesses the properties and characteristics of films from the 1950s.
That has always been the general thrust of our argument, and it should remain so. Yet you constantly compare the negative aspects of such an emulsion with the advantages of a modern one (…whilst remaining silent about the undisputed benefits at the same time…).
Things like ease of processing and emulsion consistency have improved significantly. Drying processes and other objective quality parameters have also been improved considerably. However, the emulsions had to be adapted to the modern machines each time. And that means they have been constantly modified, which is why an Efke film produces images with a different look to a modern film.
Furthermore, high process consistency always means fewer opportunities for creative influence, and thus less creative freedom (e.g. for the fine art printers mentioned who bathe the efke in PYRO or for transfer processes, etc.)
Incidentally, it is undisputed that a single-layer 25 ASA film is among the most sharp films that can be produced.
And the fact that such a film exhibits a fantastic Schwarzschild effect (namely almost none) also distinguishes it from a modern multi-layer film.
On the other hand, it reacts more sensitively to overexposure. So, to take a very concrete example:
Advantage: Schwarzschild effect
Disadvantage: sensitive to overexposure
CONCLUSION: I would be wary of making sweeping generalisations that old is bad and new is good, or vice versa. Both have their pros and cons.
If you like the Efke look, you go for it. And there are tens of thousands of photographers worldwide who do.
If it were up to you, they’d all be fools who can’t grasp the great achievements of technology. I tend to think they are individualists who judge the finished image rather than some production parameters. The Efke look is unique and distinctive. Just because you don’t recognise it (which you can’t, if you’ve never photographed with Efke) doesn’t mean you have to seize every opportunity to disparage the film, and do so with such aggression that, by implication, everyone who uses it is made to look almost like an idiot.
First and foremost, of course, me – the one who spends all day spreading lies to cheat poor photographers and palm off rubbish film on them.
Do you really think that with such a strategy, one could successfully stay in the market for 12 years with steadily rising sales?
Do you really think the success of efke can be explained by customers being dissatisfied and being ripped off?
Everyone just buys a single roll to test it out at the start, and then the ten-packs fly off the shelves here. Time and time again.....
You don’t use efke films and, for some reason, you’ve got it in for me, FOTOIMPEX and everything we do. I don’t know why, but why don’t you just leave us alone or speak your mind. Tell me where I’ve stepped on your toes or what’s bothering you, so we can sort this out. I’m getting tired of splitting hairs.

Mirko,
CATALOGUE:
>> Compared to an APX25 or Techpan, the Efke is the better choice for artistic photography.
>> Although the Efke doesn’t have quite as much fine grain [as the APX25], it has better grey tones and almost double the true speed!
FORUM:
>> I’d be wary of making a blanket statement that old is bad and new is good, or vice versa. Both have their pros and cons.
>> Ferdinand took this to mean: Mirko says efke is better than KODAK and starts ranting.
But what Mirko actually means is: efke or Classic or Foma or “whatever” is DIFFERENT from XY, and if you like that particular look, you get a great film at a superb price.
Now please don’t say that’s taken out of context or quoted incompletely. Anyone who doesn’t see the contradictions here is BLIND!
Ferdinand
MirkoBoeddecker
Ferdinand,
Quite apart from the fact that you’re simplifying the idea that it’s ‘better suited to pictorial photography’ (which, by the way, refers to Techpan plus Technidol) as being ‘generally better than’—my actual question was why you’re
always looking for contradictions everywhere
you go!
And right down to the seventh sub-level of the twelfth branch, if you have to.
That interests me. You’re not helping anyone, you don’t make any informed contributions, and you’re not even an efke user.
What drives you to want to uncover supposed contradictions everywhere?
Mirko
rherz
Hello Ferdinand,
This is a blind man writing to you!
The Efke (25) has better grey-scale reproduction and higher effective sensitivity – the APX25 has a fine grain.
Where’s the contradiction in: ‘They all have their pros and cons’?
Now do something good for your health, stop reading the Impex catalogue and avoid posts about East German films, wherever you come across them. Otherwise, you might just have a heart attack from all the excitement and die. And poor me (a teetotaller for health reasons) can’t even open a bottle of bubbly to celebrate. :) :P :lol:
You can just treat Efke and his cronies the same way I treat the T-Mäen: I’ve decided against it and am staying out of it (I don’t even read the posts about it anymore, because I can’t say anything about it anyway!)
Best regards
Robert
PS: Mirko – looks like you’ll have to move these posts away from the main thread again – sorry.
Gast
Mirko,
The presence or absence of contradictions in the product description is one (NOT the only) factor in reaching a RATIONAL purchasing decision.
In that respect, I would like to put your statement—that I am not helping anyone—into perspective.
Spreading rumours (keyword: ‘silver content’) is certainly not helpful in this context.
Ferdinand
Gast
@rherz:
If there’s a second reason for my posts, it’s to read your reaction. As we all know, laughter is the best medicine, so you don’t need to worry about my health.
MirkoBoeddecker
Ferdinand,
but you’re not actually buying anything, are you?
If you look hard enough and long enough, you can find a contradiction in almost any statement, especially when it comes to subjective perception. And ultimately, the result of a photographic process is the viewer’s subjective perception.
If it were up to you, we’d have to reduce all product descriptions to numbers – just to avoid the tiniest possible error or contradiction.
How boring the catalogue would be then!
Contradictions exist everywhere when you look at a situation from different angles.
The origin of your perspective remains a mystery to me.
No one is complaining about efke films. No customer feels cheated. At least, we haven’t received any such complaints.
Who do you think you’re trying to help?
On whose behalf are you running this campaign?
Does anyone other than Ferdinand still doubt that the silver content of modern emulsions has been reduced with every new development?
No one but you has ever questioned that.
You’re now demanding that I meticulously document which film contains how much silver and compare everything in detail.
But I won’t do that. It’s unnecessary, anyway.
Anyone who doesn’t like the grey tones of efke won’t buy it a second time. Just as I did with TMax.
The statement stands as it is. Efke films are still cast according to the original ADOX recipes and have only been adapted where necessary. At no point has there been any attempt to reduce the silver content for reasons of production costs. According to tests carried out by efke themselves, they have concluded that, compared to modern films, efke films have a significantly higher silver content – in a few cases even more than double. Whether apples have been compared with oranges, I do not know. The fact is, for me: the film has superb grey tones. And the first subjective conclusion is: “Of course, it has that old, high silver content, which is hardly to be found anywhere else these days”.
So that’s what I’ll continue to write about this film.
You’re acting as if people buy films just to extract the silver and sell it on the black market.
We’re not selling cars here, which you buy once every five years and where it’s naturally annoying if it ends up using more fuel than stated.
We’re selling films. You shoot them and develop them. If you don’t like the result, you don’t buy them again and you’ve wasted the incredible investment of €2.90. That’s just a lesson learned the hard way. I’ve had to pay that price with quite a few other films too :) despite the high ratings they always get in the big photography magazines (right next to the industry’s full-page adverts).
Please, who do you think you’re trying to protect from what here?
Mirko
Gast
Mirko,
I’m trying my best, but what you’re writing just doesn’t make sense. Knowing you as I do, I doubt you even care. Never mind.
I’ve just got one (1) request: as you’ve realised by now, I’m a tough nut to crack. But please stop this nonsense of accusing me of posting *on behalf of someone else*. That really is the biggest load of rubbish.
