How many of you do gear accounting? In anticipation of the imminent arrival of my first child and the lifestyle changes that will entail, I just picked up a used O12-40 after hum and hawing about it ever since it was released. I got it for 650 NZD (trading my O12-50 which was missing the original lens cap). Being such a high value item, I set about updating Lens Tag and insurance records... discovering that I hadn't done so in a long while. I got a shock when I looked at the total estimated value based on current new prices - about 9k NZD! How much had I spent over these 2 years since getting into m4/3? Just under 6k apparently, after trawling through my records. A slightly more comfortable figure... boy, this hobby can get expensive.
