As I have had an interest in photography for a good few years now (late 60s) I have accumulated a fair amount of equipment. Luckily for me Pentax retain backwards compatibility with almost all of their equipment so therefore there is not much need for kit to become redundant! Just means the collection becomes larger over time!
