I don't recall a folding camera with a long ass shutter though interestingly, Isonami has the biggest(?) camera out of the girls
It's pretty common for large format cameras to be used with a cable release, many don't even have a shutter release button but require a cable. Back in the old days when large format folders were popular, film emulsions were typically very slow (ISO 5 to 16) and required long exposure times. Modern large format cameras are mainly used by landscape photographers who are only going to shoot on tripod and therefore a cable release is way handier anyway. Large format press cameras are an exception, as they were often shot hand-held with flash, until smaller film formats eventually replaced them.
My one gripe about DSLR from the early 2000s is that they were made in those intermediate years where large digital cameras were starting to catch on, but the technology was too new to be used with a shutter release cable of any type.
You can't use the old (literal) cables without an adapter, nor the newer electric/digital cables because they don't have a micro usb port of any kind.
