Having a camera helps :-)
Life in 35mm land started with an Olympus XA - a truly wonderful bit of engineering. Other Oly gear followed in due course, culminating in some OM-4 bodies and a modest set of lenses. Several Oly digital cameras followed, notably a 2100UZ. Eventually, micro-4/3 appeared, with adapters to give those old lenses a new lease on life.
Current kit includes a Olympus OM-D, Pentax K-5, and a Ricoh CX-4 point-and-shoot. The 2100UZ still gets an outing, too - it turns out be fairly sensitive to IR light.
