Hasselblad 70mm is it still possible?

[mshchem]

So I see Ilford still offers 70mm HP5 film stocks. Perforated and not perforated. Will either of these film stocks work with a 1968 vintage Hasselblad 70mm back? I bought a mint back, mostly because it was cheap and looks cool. I have a darkroom and big enormous Nikor reels and a non-daylight tank.
I have no reason to do this, but like Mt. Everest...............
Are the metal cassettes reloadable? Which film? Perf or non perf, or is it even possible?

The "Are you crazy" option made me laugh, but I am too respectful to answer that option. 70mm has its use and provided you find the film in the right format and you are equipped to process it, why not?
Important is to get "Double perforated Type II" film.

It is might understanding that the cassettes are not only reloadable, you also need to reload them yourself.

There are 2 kind of 70mm backs, the 100-200
http://www.hasselbladhistorical.eu/PDF/HasManuals/70mm.pdf
and the 500:
http://www.hasselbladhistorical.eu/PDF/HasManuals/70-500.pdf
I assume you have the 100-200. The 500 ("intended for large scale film consumers") is probably a pain to use (needs a battery) and carry around. The applications it was targeting are probably better served by digital nowadays.

There is also some interesting info on that threat - look in particular at the posts by KParatt:
https://www.photo.net/discuss/threads/hasselblad-70mm-magazine-film-questions.437553/

In my case, no 70mm - I want the convenience of 120. I am also not equipped to load and process 70mm, nor do I "need" 70mm for cost reasons with the low amount of film I expose.

I did not know that Ilford still offered 70mm perforated film. Even so I do not shoot a lot of film at a time, so I still will pass on it for my Hasselblads.

 

[mshchem]

Okay, I voted for are you crazy, well because I have several friends who would testify to the fact.
The back I ordered is the 50 shot back. Kodak, in the good old days sold a couple of films in loaded cassettes. But as near as I can see both Kodak and the Hasselblad branded cassettes are reloadable. It might be fun to try, would need to see what minimum order is from Ilford. They do offer both double perforated and no perforation in 70mm in annual sale. I don't even have much of a fondness for 220, so 10 or 11 feet of 70mm would be something.

But I want to play Neil Armstrong and take waist level pictures with a wide angle. On Apollo 11, Armstrong had the only Hasselblad that was used while they were out walking around. There was a black EL inside the LM for interior and mapping work. I think they only had, on the surface a couple backs worth of film, crazy. God I miss the 20th century!

fwiw; I shoot 70mm with RZ67 (no Hasslebald for me, I'm not crazy)

I've got two RZ 67 II cameras as well. I got the Hasselblads because at my age I am getting things that I've always wanted. Both systems are pretty darn cool!

The last Ilford ULF run I checked (it was 2-3 years ago) price per 6x6 frame of 70mm film and 120 were the same or very, very close. So it does not make any sense for me to use fresh 70mm film, especially when you have something like 1 foot+ of film used as leader in 70mm magazine per load. It's easier to just use 120, smaller magazine on the camera, decent number of shots. I have nice stash of expired 70mm film and I will use it. When all of that is I don't think I will buy fresh 70mm film. If you use you Hasselblad like machine gun, then 70mm totally make sense.

This arrived last week from B&H, they discounted a slug of 70mm HP5+ so I bought a roll of 50 feet about 25% off the regular preset Ilford price. I think I will load these into 12 and 24 exposure rolls.

My current 70mm favorites are Kodak WL Surveillance film (a lot like old original Tri-X IMO) and a stash of original Plus-X from around 1981. It has gotten better with age

And of course for years you could get the Rollei 400s very cheaply from Germany.

Just to show you that you're not the only nut here.

 

[mshchem]

I just checked no more discount, they do offer 50 foot roll special order for $218. That's more than double what I paid for the back. Looks like I will just be pretending to be Neil Armstrong. The back I have coming is beautiful!

 

[Nokton48]

There is normally no discount 70mm vs 120 in terms of cost. What it gives you is massive 70mm firepower.

70mm 2502 Jobo Reel by Nokton48, on Flickr

This is a JOBO 2502 reel I made wider, by hacking in a plastic 35mm cannister cut down, from a roll of Efke 25. The other cannisters won't fit! So I can run up to 220 lengths of 70mm in my JOBO Multitank 2500 units.

That's genius. You need to post the length (height) of the canister sometime. I've got a massive Nikor tank and reel it's definitely for 70mm. It's part of my permanent collection of stuff I will never use. Along with my 33 foot Hewes 35mm reels. I always wondered when I had a 250 exp bulk film back for my F2 how many loops around my darkroom I would need to make while the film was drying.

 

[Nokton48]

I use wooden clothespins on a wire and cut the 70 exposure rolls into strips of twelve for hanging. I use a 70mm Kindermann tank and Kindermann reel for full 70mm loads. It requires a gallon of developer to fill properly. Not appropriate for quick acting developers.

Ilford still does the annual ULF orders, which is most likely what B&H is doing since Ilford doesn't produce 70mm outside that once a year window in so far as I know.
There's also Rollei Ortho 25 for significantly less (<$100 USD) from Europe.
Rollei 400 was available up until recently, one user from RF forum reported Macodirect is no longer stocking it.
Beyond that, you can go for some Kodak movie film, surveillance film, or expired stock obviously.

All 70mm cassettes I've seen are reloadable (Kodak, Hasselblad, Linhof, etc).

Perf or non-perf depends on the back. Linhof, Pentax and Hassy backs all have sprockets and cannot shoot non-perf without modification.
There's an official gasket replacement wheel for the Hassy backs to convert for non-perf, which is difficult to source, or you can make your own.
Most other backs I've seen are non-perf, which use a friction based advance so you can use perf or non-perf in those (e.g. Graflex, Mamiya, etc)

Then there's all the oddball stuff like Keith backs, and military (e.g. Fairchild, Graflex, etc) cameras that were designed for 70 mm. Most of these require loading the film on the original 100ft spool though, save the KS-6.

There are 2 kind of 70mm backs, the 100-200

and the 500:

Not trying to split hairs, though there were a lot more than two types of 70 mm backs from Hasselblad:
A70
70/100-200
70/200
70 DM-100/200
70/456 (this one was special order only)
70/500*

* I've seen a couple variants of the 70/500, though nothing from Hasselblad giving them officially separate designations.

70mm Infared 2424 by Nokton48, on Flickr

This is the same emulsion Kodak released as 35mm High Speed Infared. I found a 150 foot 70mm roll on Ebay hopefully it has aged OK. Also David Romano used to slit this stuff down and reroll it in 120 paper. I still have six rolls, plus one that needs to be developed. I always liked 35mm High Speed Infared in D-19 back in the day..

This is the 70mm Rollei 400s in Rollei Supergrain developer from Freestyle. As you can see it has a unique look somewhat infared. It is exactly the same emulsion as the 70mm Agfa Aviphot which I picked up from an aerial mapping company that was hooked up direct with Agfa. Later the 70mm Rollei 400s came along. Perhaps they will make some more. I remember contacting Macophot and at the time they had hundreds and hundreds of rolls in stock.

On the right is Kodak WL Surveillance Film in a hot rodded Hartblei 1006 body 120mm Vega lens 283 direct flash. On the left is Plus-X Aerographic clip test. This is high speed film with low grain

Both films produce "beefy" high speed negatives with lots of detail.

Developed in replenished Freestyle Legacy Mic-X stock solution in Kindermann 70 plastic tank and metal reel.

No starwars please! I choose the best i.e. Rolleiflex sl66se Still working on 2x 35mm film together tru the 70mm back.

Where can I find the reloadable metal 70 mm for the Hasselblad 70 back?

 

[Nokton48]

Ebay. You will need two as a minimum. Search "70mm film"

 

[mshchem]

I think I will hold off for a few days. These kinda things tend to snowball, I don't need to spend a bunch of money. The back I bought is beautiful. When I told my wife that the Apollo guys saved the magazine and threw the cameras out the door she didn't believe me.

By the way I suspect you and I have enough stuff we could each fill a moving van.

 

[Alex Varas]

I have a Inos II with 116 film, now waiting one non-perforated roll from Ilford and a Yanke tank with a reel for that film.
Hopefully in a couple of week I will be using the camera again, 6.5x11 is a big negative!

 

[gorbas]

Alexvaras, you could also use Paterson reels for developing 70mm film, just arranged in slightly different configuration than for 35mm-120.
