Yeah, the increasing problem with film cameras from sock drawers and cupboards is that they're liable to be not in the best condition, have gummed up parts, worn out gears, corrosion, lens fungus, failing old electronics and so on, and the chance of buying a wrong 'un increase.
The part supply is diminishing and the people who used to fix them for a living are retired and not getting any younger.
An affordable, new, reasonable quality name brand film camera with warranty, freshly made parts and trained up engineers who can fix them would be a big step forwards and remove that kind of uncertainty connected with buying old cameras. I've got a few old cameras myself which went wrong and aren't worth fixing even if I could find someone who could fix them and I had the disposable income to pay for it.
But its early days and we need to be careful of counting our chickens before they hatch.
After all, whatever happened to that new super 8 camera Kodak were supposed to be bringing out some years ago?
