Efke IR820

Wirehead · Post by **Wirehead** » Mon Mar 12, 2007 2:47 pm

Apparently the Maco 820c has been resurected as Efke IR820.

Everybody's claiming that it's *exactly* the same as the old Maco stuff and that Efke was making the Maco film all along.

I've got a few rolls on the way. I'm going to try it out and see if it's true.

OK, keep us informed.
Efke (Fotokemika nova) has misused the Maco patents so far. One of the reasons Rollei/Maco have given the order for a new IR850nm film (iso 100) to Gevaert in Belgium. (Based on APX100 extended IR emulsion

)
Interesting to see in such a small market two new IR films soon .....

Oh, and you can't forget about the return of SFX, or the IR film that J&C has been threatening to make.

I guess next somebody will be talking about restarting production of Konica 750 or something.

I didn`t know Gevaert was still operating. Is it the same factory that was in Mortsel, Antwerp in Belgium?

Yep, I fact they were the R&D lab from Agfa who went bankrupted in 2005.

*does a dance* It's so good to see activity in the film market

A question for Robert, can you clarify the relationship with Rollei, Maco etc ? I'm a bit confused about who is making what and for whom.

I've used "Rollei IR" in the past, is the Efke version going to be different?

We will be adding the new Efke IR820 film to our store in the next few days, and full product details will be provided.

I never cared much for Agfa films in the ISO 100-400 speed groups, I did however prefer APX 25 over Pan F. Now, the speed to grain ratios of modern films have greatly improved with films like 100TMX, 100 Delta and 100 Acros which have only very slightly more evident grain with a one to two-stop speed advantage.
The I.R. film looks like an interesting alternative to Kodak HIE if it`s available in 120 size rolls as well as 35mm.

Maco (Stapelfeld-Hamburg) bought the brand name Rollei for their new production films.
They have two production locations:
1) Filmotec (former OrWo, Wolfen-Germany) for their R3 (in fact a TSF), PAN 25 (a modified NP15 OrWo) and the Ortho 25 film.
2) Gevaert, (Former Agfa R&D lab, Mortsel-Belgium) for the IR820/400, CN400 pro (C41) scanfilm and the RSD (slide direct), based on microfilm and Agfa direct dup film technology.

Their FORMER Maco IR820C was an extended Efke 100 film sensitized till 820nm. This patent is used (or misused

) by Efke Fotokemika nova to produce their own IR film now.
In the mean time Ilford has re-introduced their SFX (in fact also a TSF). But I thought available in 35mm only now. Same like the Kodak HIE: 35mm only.
Rollei/Maco will introduce their own new type iso 100 extended IR film based on the APX100 and then to approx. 850nm. This new IR Rollei film will be also produced by Gevaert. Available in 4x5", 120 roll film and 35mm in about 2 months.
The Rollei IR820/400 is still available in the same formats. But for this IR film you NEED a 695nm or 715nm IR (black) filter. A SFX (Ilford) filter or Hoya R72 or Cokin 007 (720nm) is also OK.
But with a HIE you will get wood effect with a dark RED filter. The same filter will be possible with the new Rollei IR (850nm) film. This film is MORE sensitive in the IR area.
This new iso 100 infra red film will be also available in our Fotohuis program soon.

Ilford announced that SFX would be in 120 as well as 35mm

So your options for 120 is SFX, Efke IR820, Rollei IR820/400, and Rollei IR850.

Your options for 35mm is SFX, Efke IR820, Rollei IR820/400, Rollei IR850, and Kodak IR.

Dono, SFX, Efke IR820, and Rollei IR850 all sound very interesting for when you want a finer-grained, halation-free IR image.

We now have EFKE IR820 Infrared film available in both 35mm and 120 formats. Other formats, including sheet film and 127 will be available in the near future.

You can purchase Efke IR820 here:
http://www.digitaltruth.com/store/cart/ ... c-223.html

This film was previously sold under the Maco brand as IR820c Precision Infrared and includes an anti-halation layer which was absent in the "Aura" version. The data in the Massive Dev Chart for Maco IR820c will be moved into the Efke section shortly, and we will post more technical data next week.

Well, I've got some new IR filters, so this weekend, I'm testing.

Wirehead · Post by **Wirehead** » Mon Mar 26, 2007 12:11 pm

I tried it out...

Not so different as the Rollei IR820/400 film:

Yah, but my filter set right now is a 25, a 29, and an 87 filter and it doesn't sound like the Rollei IR film works very well with any of them.... the 29 being not strong enough and the 87 being too strong.

From a user-friendlieness perspective, the Efke film inherits the quite excellent Maco datasheet and the SFX has the usual excellent Ilford datasheet.... whereas the Rollei IR datasheet just plain sucks.

I figure I'll wait till I can get SFX and get an 89 filter before I try doing a proper apples-to-apples comparison between the various films.
