I would say a Pentax MX SLR. I miss the days of film. Adjusting the f-stop, shutter and focus with the touch of three fingers in just moments while you looked through the viewfinder and quickly snapped a high quality pic. But sadly those days are gone for us simple folk.
The digital cameras today take forever to go into the menus and adjust these things if you want to change the pic from what it wants you to get.
But they do an excellent job for the most part. So what more do you need in a camera while cycling that your smartphone doesn't give you?
