Well there's a few things I haven't heard in years, Zenith, 110 I had both of those. I took a half-frame camera to the Falklands, a Minolta I think, it enabled you to take 72 shots on a 36 frame 35mm film.
I also had an Olympus XA1? 35mm camera which was cracking, I bought a side mounted flash for it, it was very wee, but took great shots. Left it in the glove box of a hire car on Guernsey
Now got a couple of digital cameras and an iPhone that does everything!!! How far we've come from the box brownie
