70mm Film FUN up ahead

Hasselblad 70mm loader! Have it beside Alden 70

Hasselblad 70mm loader! Have it beside Alden 70

Anyone knows the Hasselblad 70mm loader? I have one. Film must be on spool not core. there is ZERO axis like in Alden 70 where there is also an adapter for different cores.
Alden 70-counter is better (no cogwheel like in HBs-no unperforated film possible). But i remove the Alden counter since i dont like metallic arm sliding over film. Must organize manual- hope seller has it. Images of parts will follow.
Hope its really Hasselblad or is it Watson? more imges next

Never seen one of those before, it is not a Watson. I've got the Watson loader, here is what it looks like:

Before having time to upload more images here some weird news.

The box with the 70mm-handle is onlky sticken ontop no screws nothing. it can fall apert when no film(donor) and loaded cartridge is mounted.

inside at the main rim there are traces of glue seller telling its from a tape securing whatever, film? box? film is inside and box is combined with second insert by 3 screws. one with a bolt. see images.

clear could be that without spool(film only on core) film will wooble around touchig the walls. Very bad decision of the designers not adding an axis. the alden has two adapter-options for the axis.
for unperforated film counter cannot be removed easily, maybe a dummy made.

Images coming asap.
In my opinion this cannot be from Hasselblad. i will ask them.

Watson=Alden
To avoid the counter-lever touching the film i removed it and covered its hole with opaque tape. yes one has to find out how to rotate for certain lenghts. could be difficult if film is this or ultrathin PE0 e.g. 0.1mm like vericolor HC(100) can be loaded with 6.5m. technical pan may be same thickness.
Good are magazines which can be zeroed like Mamiya RB 67-70mm after 65 shots(if i dont err) to shoot more than the max.
When counter is dead(i have such an insert) zeroing counter after the max(in counter) was achieved is not needed. its by opening the door (in darkness). one could zero before reaching the end to avoid darkbag by shooting twoi empty shots and exposing that part to light when having to zero when counter is working. agfa has PEO thickness 0.06mm which would lead to real extralong film in 70mm cartridges. How thick is Technical Pan 70mm? same as 35 and 120 i guess.

How to get started in 2020?? help

Hey everyone, sorry to jump on this post, but Ive been looking everywhere online and cannot find anything, so i figure here is my best chance.
I have a 70mm film back for my hasselblad, and two cartridges. I don't really have anything else, such as reel, tank, loader or kind of importantly 70mm film.
the film i love is the rollei infrared 400 which was available on macodirect in 70mm which is why i saved up for the back and cartridges however now they have told me they have sold out which is sad. Other than buying multiple rolls from bh of just hp5 is there any alternatives? i do not want to invest with a reel or loader if i have nothing to load.
any help or point in the direction will be much appreciated thanks!
 
Hi guys!

I'm looking for pictures showing HR-50 modified to fit RB67 back.
I'm thinking of unperforated film, so i need a new back.
I think Mamiya 70mm back can be modify too...

A Lot of pics of the thread are out... 🙁🙁🙁

The Graflex 70mm and the Mamiya 70mm will run unperfed 70mm stock. So also will the Beatty Coleman Transet 70mm backs.

The Graflex and Beatty backs are Graflock types, so you would need the proper Mamiya RB67 adapter to take Graflock.
 
I had some good 70mm fun last Sunday. My wife and I have been cooped up like everybody else in the world, so we took a relaxing one hour drive and visited an impressive outdoor park not fall away. An old estate, with georgeous vintage gardens, lots in circular patterns. So I dusted off my 500C/M Hasselblad, and two lenses: The 30mm F3.5 Zeiss Distagon black T* fisheye, and the 100mm F3.5 black Zeiss T* Planar, one of my fave lenses.

I brought along two 70mm A70 Hasselblad film backs, both loaded with Kodak WL Surveillance Film, which is bank recording film, I believe. Mine is military surplus when even had the govt contract number pasted to the boxes. I had no idea how many exposures I had loaded into these two backs. One stopped running at 15, the other went to 31 exposures. So 46 6x6cm 70mm exposures in all.

70mm is so much fun. I think my fishy pix will be quite interesting; the gardens are truly impressive and fisheye is the perfect view for some.

Previously I have run those WL films in ADOX Borax MQ which is a D76 derivitive, than I learned about from TomA. WL Surveillance is a high speed recording film, alot like old Tri-X in that it is about 400/800 EI with great shadow detail, but can be pushed as high as 3200 according to some Kodak lit I recently data mined. Really beefey negs are the reult, which I happen to prefer.

I will reload the 70mm cartridges with about 24 exposures each, want to try more of my stock of films. Like my fresh 70mm HP5+ and my Kodak Plus-X 70mm Aerographic which is a lot like old Plus-X with slightly different spectral response.

I have to thank you, Dan, both for starting this thread and for your enthusiasm for 70mm. Sharing your knowledge and experience has been key to my own interest in it. Also to Cal for his very helpful development suggestions.

It hasn't all been plain sailing, with a few teething problems including some magazine issues. But I'm getting there and have learned a thing or two in the process that might possibly be helpful to other Hasselblad users. I mention these within the (rather long, sorry) article I did last week about 70mm.
Cheers,

Hey all. I'm another new entrant into the 70mm club with an RB67 70mm back on the way to pair with my Horseman 842 (standard Graflok 23 back).

Since fresh Rollei 400 DP seems to be delayed by the current state of the world I've been looking for alternatives, most of which seem to be non-perf. Mercury Camera has a Graflok 23 page which suggests modifying the RB67 back by grinding down the teeth of the film advance and wrap them with orthodontic rubber bands to convert the back to non-perf friction advance like the Graflex RH50. I'm actually also looking for an RH50, which I've seen others convert to Graflok 45 and even mention of conversion to RB67 (using that Mamiya's pin registration rather than the graflok 23 attachment used by the roll backs), to see if it's feasible to convert it to the Graflok 23 standard.
Has anyone got experience/thoughts/information about performing those types of conversion?
 
Graflex RH50 70mm Backs by Nokton48, on Flickr

These two RH50 Graflex 70mm backs are 4x5 Graflock type.

The one on the left was for the Graflex XL, has an XL mounting plate and four shiny steel pins. Unscrew the pins and remove the mounting plate, and it's the same as the the other one (on the right).

I bought the one on the left from an internet friend for $20 🙂
 
Very cool. I just picked one up off the bay for 30+shipping I'll at the least duplicate your modification for use on a normal Graflok 45 back. Is that remaining 4x5 plate removable from the rest of the back? Perhaps it would be possible to 3D print a graflok 23 compatible plate which screwed into the RH50 back replacing the 4x5 one. We'll see when I have mine in hand.


I'll have some unperf 70mm here by end of week so hopefully I can start testing out the feasibility of converting the RB67 70mm back to non-perf. If I make any progress I'll be sure to report back.
