This interesting item was included with a recent purchase.  I have not found any information on it so I'm asking the experts. 

Using it seems straight forward although I see no way to use a dark slide so you would be committed to using the whole pack or lose the remaining shots.

I think the OM means it uses an Olympus adapter. 

Any help welcome and thank you in advance. 

Russ

RARE & very cool -- Congrats!!

 

(I thought these had a pneumatic shutter, so you could take one photo at a time.)

Yes sir. You squeeze the bulb to open,remove your thumb from the top and shutter stays open. Do it with the hole covered and it closes.
Not sure how light tight the shutter is.
Also you need to use the ground glass to focus. So it seems.
It came from Steve with that awesome C-8.

It looks like it uses the kind of pack where each sheet has its own cover. You pull that out until it stops, to uncover the film, take the shot, then pull it the rest of the way out to break the chemistry pouch and squeeze it between the layers. After a given time, you peel the sandwich apart to get the print (and then there is a coating you spread over it with a sponge-like wiper).

I remember those. B&W. You could put the negative in your fixer tray to preserve it.
About 4x5. Still remember the smell of the wiper in the black tube.
Thanks Chip

Wow, that's very interesting! 

 

I haven't seen anything about these cameras until now. I'm assuming that these were made by Sky Scientific? From the pictures, it looks like the Ground-Glass is part of the cartridge that fits into the camera Russ? 

 

Since these have a bayonet (this particular one is OM) did they make these for use with camera lenses, or more for Prime-Focus via telescope?

 

Too many questions, I know.... I've got a few old Film-oriented Astro books here - but I'd figure one of you here would know about these, and I'm curious because I am still working my way to getting into 35mm in this age of the "the modern." But I've always been behind the times I 'spose. 

 

Man, that is super cool though. I have fond memories of the old Polaroid camera that many family members had back in the 1980's when I was a kid. Probably got a shoebox somewhere with the shots too.

 

Best,

Temp

The ground glass was glued to what looks like the skeleton of a film pack.
Instructions would be helpful.
I think you remove it after you have it focused and then put in the film.
Just a guess.

I've talked online to a few very helpful folks the last few days.

This is cool.

Sounds like you know about as much of it as I do.... lol.gif but that sounds like it, yeah.

 

I did do some sleuthing around, and ran into one that was similar to yours posted on the classifieds here. From what I can tell, these were custom built by Sky Scientific... using, you guessed it... Polaroid backs. From there, I ended up going down a rabbit hole.... apparently there are many different variations of these film backs. Yours might be what was called a "Land Camera Back" perhaps. If so, these use "pack film" and that might be what Chip is referring to in post #6. Perhaps he could elaborate, as I'm not familiar with that one at all.

 

Polaroid stopped producing "pack film" in 2009 and Fuji ran some until 2016 then ceased production according to wiki.

 

But, I did find some 4x5 ( I think) backs which look similar to these,  and it looks to me like the flange / shutter assembly is simply bolted to the film back..... so it could be easy to retrofit to 4x5 - maybe? That would be a cool one-off project... if such "instant" film is available in that format, that is.

Not sure you can get any film that will work with that back..

Most Polaroid "Astro" cameras were adaptations of the microscope camera.

Hi there, this is a Polaroid Packfilm back for, well, packfilms, which were designed to contain peel-apart instant films within a filmpack.

 

Unfortunately, both Polaroid and Fujifilm have stopped producing packfilms, which made them EXTREMELY EXPENSIVE.

 

FYI, the average price for Fujifilm FP-100C (ISO 100 Color film) each pack is about 60~100 USD for now in 2020.

Since that's just an ISO 100 film I don't think that you'd be shooting with that...

 

Fujifilm made some FP-3000B(ceased production too long ago) which is ISO 3000 B&W film, might be matching your needs, which is costing about 60-100USD too in 2020.

 

All those films are expired but still can provide very optimal results, if you fully understands them. But honestly I don't think that these films suit astro-photography anymore. However, if you want to, there're still some other options like using the integral film backs instead of the peel apart film backs.

 

FYI, there were many costumed integral film backs made from those Fujifilm Instax cameras, which are using very cheap ISO 800 Instax integral films. And if you wish to take one step further, there are some real polaroid integral film backs (really rare though) which can still be used with today's Polaroid Color 600 or 70 films. The 600 type is about ISO 640, while the 70 type is about ISO 160.

The specific "back" that you've owned is actually a complete packfilm camera body, just without the lens needed. You need to find some OM compatible manual lenses to make use of this camera. Of course, you'd be needing those expensive packfilms too.

 

It's not a 4x5 film back btw. And honestly Polaroid has never made a 4x5 film with packs. They made just 4x5 readyload films which were basically an envelope containing one shot of peel-apart instant films. However this technology was also authorized to Fuji so Fuji made their readyload system too which is renamed as quickload. Polaroid also made the readyload films for Kodak, containing 1 or 2 shots of 4x5 Kodak films, both negative or reversed. I owned a few loads of Kodak E100VS quickloads, really beautiful solution for 4x5 format, dust free and easy containing... good old products :(

 

Fuji made some 4x5 packfilms and suitable filmbacks, though it's even harder to find these days.

Would love to see any photos taken and would also like information on finding film.

Definitely digging yours.
