I'm a wee bit older than most of you, I think. And started a wee bit younger too. I started High School in 1968; my mom gave me her Argus C3 and my grandfather loaned me the same 1949 Rolleiflex that my uncle had learned photography with.
But as 1969 and my sophomore year dawned, I knew that I needed a modern camera to do the Photo Staff work I wanted. Of course, I had no money ... I kept looking at the NY camera shop ads and hoping I could put the money together for what was then, new, a Minolta SRT-101 ... on sale with 50mm f/1.7 lens for $159.95! For me, at age 13, that was an amount of money beyond my wildest dreams. So I worked odd jobs all that Summer and managed to put together about $90. Sigh.
My uncle came by one day. "I hear you're looking for a camera."
"Yeah, but I haven't got the money and school is starting next week." I sighed.
"Hmm. How much did you make this Summer?"
"About $90. But the Minolta is $160."
"Eh. You don't want that junk. Give me your money and I'll get a camera for you."
He showed up the next Sunday with a box for me. In it was a Nikon F Photomic FTn with Nikkor 50mm f/1.4 lens.
"How much was that? I don't have any more money!"
"It's yours. You don't owe me nothin'."
I lived with that camera for the next five years and made thousands of photos with it. I sold it to a good friend at some point in the middle 1970s and moved on to other Nikons (F2, F3, FM, FM2, FE2 ...), and Leicas, and Mamiya medium format cameras, and another Rolleiflex. Forty years later, a friend sold me his black Nikon F Photomic FTn and I realized just how nice it was. But i had plenty of other cameras by then, and I gave it as a gift to a High School friend who had always wanted a Nikon like mine. Another decade past and a guy on another photo forum sends me a note.
"I found a Nikon F that my friend loaned me and I'd forgotten about. It's been sitting in a box in the basement for the past dozen years ... I can't find the lens ... and he passed away. His wife doesn't want it. Would you like it?"
"Sure. Better than throwing it away." It's a 1963-64 Nikon F plain prism. I have the selenium cell clip-on meter too, the selenium cell is dead and needs to be replaced. I had it cleaned, serviced, and dug up a Nikkor 28mm f/2 and a MIcro-Nikkor 55mm f/3.5 for it.

Approximately 1963-1964 vintage for the body, 1971 vintage for lens
That was a dozen or so years ago. Still have it, still occasionally take photos with it. Still feels like the perfect 35mm SLR. For me, for my old muscle memory.
😉 Funny how these things can get under your skin and bring back memories of a lifetime ago!
