My father-in-law introduced me to photography (because I was interested), soon after I married his daughter. He first lent me a fully-manual folding-lens camera with a separate light meter, on the basis that that was the way to understand exposure and so on.
But his camera was a Pentax ME Super, so I aspired to one of those, eventually getting one second hand, and after that a Super A that was quite battered and therefore inexpensive. K mount was good on a budget anyway - lots of brands use it. So I started with a Petri (Cosina look-alike) from Dixons.
Anyway, I've stayed with Pentax throughout, now with a K70 and a K30 (it's a long story why I have two, and more complex than the usual n+1 stuff).
I do have a fair amount of the old film gear - mine and my FiL's, after he sadly passed away. I don't like to let it go, but I always use the digital now.
