35mm film camera. My first true camera. I learned how to take photographs on this camera which I see as a good thing. I only had 20 pictures per film roll. If I was going to press the shutter button I had to be sure I would not be wasting film. I need to know what to expect the final picture to look like. I needed to understand ISO, shutter speed, aperture, and exposure. And since I didn't have the capability to just shoot off a hundred pictures in one go, I spent time choosing my settings and the results stuck in my mind.
A more modern 35mm film camera.
My first digital camera which wrote the photos to a 3.5 inch floppy disk.
My first (and recently acquired) DSLR.
