When I was 16 I started shooting on my mom's old Nikon F(something), unfortunately the shutter had a tendency to jam and quickly became almost unusable. She got my a Nikon FM3a for my 17th birthday, I had no idea just how awesome of a present that was until much later.
Fast forward five years and I still love the crap out of that camera, it's by far the perfect 35mm camera for me, but it's been sorely neglected as of late. I'm to distracted by my 4x5 and my holga among others.
