When looking through ebay you often see the Agfa Copex microfilms for sale, dirt cheap. I bought a roll, and didn't realize it was unperforated. Do'h. Oh well, bought 35mm-120 converter from ebay. The thing didn't fit my bulk loading cassettes. Do'h! So I just crammed the thing into my hasselblad back and put some bubble wrap top and bottom and said fuckit.
Shot a couple of quick test rolls yesterday and today. Yesterday I fucked up the metering, the sun had already set and I must've looked wrong at my meter because I was doing about 1-2s exposures at f8, which did feel odd but I didn't think about it. Today I went out daytime and it was 1-2s again, so a little bit better results.
I rate this film at ISO25, but I'd say it's a little bit low. Maybe due to reciprocity failure, since pretty much every shot is 1+ seconds. Maybe due to this roll being old, there is no date markings on it and who knows how it's been stored.
What I can already say about this roll is this, it scratches sooo soo easily. And fingerprints stick to it immediately. DO NOT HANDLE THIS FILM WITHOUT COTTON GLOVES. Seriously. And when loading from the bulk roll into the cassettes, you cannot "tighten it" by just dragging the film in the roll, you will make serious scratches. When wet, you can scratch off the emulsion with your finger, it's really delicate.
The film base is clear PET plastic, so base fog is not an issue. Contrast however is, as I said this is a microfilm, made for taking high contrast pictures off documents. Not for pictorial stuff. So contrast control is the tricky part. I did 1h stand development in rodinal, 1+100, and it turned out pretty alright in my opinion.
Is it worth it shooting this film? For experimental stuff, sure. But due to it being so scratch prone and difficult to handle, it's not worth it as a daily film. If you want that gritty high contrast look with maximum sharpness and resolving power, there is some interesting images that can be had with this film stock.
Here are some examples. Note the weird form factor due to shooting 35mm in the Hasselblad.
