My µ43 is not my primary system therefore my investment isn’t over the top. I have a GF1 with a 20 mm F/1.8 and a 14 - 45 mm f/3.5 - 5.6 lenses. Total cost was about $1400 Canadian. The funny thing about the cost is what I call the justifiable cost. With the GF1 with a 20 mm combination I have taken thousands of image driving the cost per frame to about 14¢. On the other hand I have take only 10 frames with the 14 - 45 mm so the cost per frame is about $40. It's not that it is a bad lens I just don't use it often. So in a sense the cheapest lens in my kit is the most expensive.
