70mm perforated films... what is still available?

Dan Smith , Feb 21, 2001; 09:50 a.m.

I am looking at a couple of older medium format aerial cameras that take 70mm perforated film. Anyone out there have a good handle on what films are available in this size? It seems not too many are still made.

B&H lists High Speed IR and Plus-X (under aerial films) and VPS in 100 foot rolls. They have discontinued Tri-X (or so their customer service people tell me -- 70mm "is no longer factory stocked and requires a minimum order of 36 rolls. Any amount over 36 rolls needs to be ordered in multiples of 18"). Ilford's customer service emailed me last fall that they no longer offer HP5+ in 70mm. Agfa offers three speeds of black and white 70mm aerial film (max speed ISO 200) in 30 meter rolls, but it is a special order item (I had a friend check in vain with several major German photo dealers last summer).

So basically it is HIE, Plus-X, or VPS

See: Old 70mm film list

I've copied the list below. The list is a little old, but most of them are still available. N. Perf stands for No perforations. There is not a ton available, but enough variety for 99.9% of photographic purposes. You have black & white, color negative, color reversal and of course Infrared. What more could you ask for? Perhaps a color negative infrared film?

Dan I knew the films were around but the processing is another matter. I don't know who it was, maybe Roland, who was manufacturing developing tanks. Somewhere in a hidden thread there is a response concerning the tanks. I have a couple of older Kodak folders (616, 617) that could use 70mm film but I didn't want to get into the developing end ot it at this time. Pro Labs doing 70mm are few and far between as far as I know. I would be interested in a lead concerning this.

Hello Dan

As noted by the other posters, not to many emulsions is readily available on the shelf. My experience (from here in Europe) is that "todays" users of 70mm film is high-volume users buying rather large quantity of film directly from Kodak or other producer. 70mm film have been used quite a lot for small format aerial photography as well as for metric purposes, where the customer is likely to buy a large quantity of film. One solution is thus to buy surplus films from aerial-photography companies using 70mm, and/or to contact them before they submit their film-ordering and see if You can fit inn a part-order for 70mm. Color-labs doing medium-format duplicates uses 70mm film (which is ordinary E6 or C41 films), and is thus able to prosess your 70mm stock as well. If You want to process the films yourself, Jobo makes all the needed equipment for prosessing up to 15' length (they also have reels for 70mm - 5' length for use in the standard-tanks in the 2500/2800 family). Kindermann have for decades made stainless steel reels & plastic tanks for 15' 70mm. Earlier, Nikor prodused identical reels but vith SS tanks. Inexpensive plastic reels for about 14' - 70mm film can be bought from companies distributing X-ray systems: seems that 70mm film have been used extensively in this field. I have one of these, an it works fine. Last but not to forget: The film-section on Ebay allways show 70mm film of some kind for sale, including often the mentioned 70mm color-neg version by Konica at low price.

Good luck to You.

(PS: Let me hear from You, Dan, if there is any 70mm aerial cameras left after You've been shopping!)

It's good to hear that someone else is using the plastic X-ray film reels for 70 mm., Tor. I have a couple myself and have been very pleased with them. But I have a problem that I'd guess many others in my situation have.....how to get a reasonably priced tank to use with the reel. The reels I use are about 16 cm diam (6 1/4") and stand about 8 cm. high (3"). I currently use a variety of pots and pans, pressure cookers, black plastic garbage bags, etc. You don't want to know - it's not a pretty sight. What do you use for a processing tank?

Answer to Peter about tanks for 70mm: To get a high-quality tank, I asked a local metal-shop (who is specializing in making stainless-steel products of sheat metals (kitchen-sinks and stuff) to make me a stainless-steel tank that fitted the 70mm reel exactly. To keep cost/work-time down, I told them to build the tank as a bucket with a push down/inside-type lid, and with an 8 cm. diameter round hole sentral in the lid. The tank is lengthened to approx 15 cm to fit on a motorized roller/agitator-unit, and thus the "bottom" of the tank is soldered in place halfway up the tank-body. In the hole in the lid, I glued in place the top part (i.e. the light-trap and the neck/filler plug assy.) of a cannibalized 35/120 plastic developing tank (the light trap/filler-cap part would othervice be the most expensive thing to make from stainless steel). This gave me an about $ 100 very high quality stainless-steel tank suitable for roller-processing. Any black plastic or stainless metal-tank with the proper diameter and a fitting lid can of course be converted to "daylight developing tank" with a top part of a plastic developing tank - it comes to my mind that cupboard where you store your cooking-pans might be a place to start searching....

Good luch

Jobo does nont produce devl. tank for 15 feet length any more. They deliver reels for 70mm films but only for 4 feet lengths, for tank system 2500. Kindermann retired from such productions completely. I am also looking for the sutable dev. tank for 15 feet rolls. Are there any other manufactures available? The reels used in X ray technology could help me, but who is producing them? thanks.

Don Roberts , Feb 23, 2001; 11:40 a.m.

Coincidentally, I have just listed two 70mm processing tanks and reels on ebay. One is for the 15' length and the other will do up to 7'. Both are Nikor stainless steel. Jobo no longer makes the 15' reels, loaders and tank. They do have the 5' length available yet. Kindermann also makes tanks and reels.

Pete Schermerhorn , Feb 24, 2001; 09:17 a.m.

Zigric,

I purchased my 70mm reels from Henken Industries in Texas about 2 years ago. The website is currently undergoing "reconstruction", but >>> http://www.henkenind.com/developingnf.htm <<< will show you what they look like, and in case you have trouble getting back to the info on addresses, etc., it's at >>> http://www.henkenind.com/index.html <<<.

The reels won't quite hold the 15 feet but I bulk-load, so it's not a major problem for me. I can get about 12 feet on a reel. Two years ago, the reels were $7.50 each, plus shipping, etc.
