Not including Camera Phones, 4.
2 were AGFA 10mp things I got as spares repairs to showcase models and sales stuff, one in silver and another in bright pink, silver had a busted screen and meant to swap the one from the pink over but sticker wrapped the pink one in Car stickers insted.
Nikon Coolpix L810, loved this thing even if it was still technically a basic Camera, still miss it but got a note from its new owner who loves it as well.
Nikon D3400, Bought it with a bit of my redundancey in Black friday sales to try and teach myself modern SLR usage, it lives in its bag mostly as I still prefer using a RF
Number 5 I hope will be a Leica but that will be a way off and if I want digital that DSLR will do for now.
Those aren't left over screws, that's weight reduction.
