I'm coming into the u43 system after using only P&S cameras for many years. I knew about the benefits, and cost of interchangeable lens systems, so I was prepared to pay $300 for a Lumix 20mm (which is, apparently, sofa seat change compared to some high end lenses). After doing some more comparison shopping, I'm finding that native u43 lenses seem to cost much more than similar lenses from the Nikon or Canon system. The new Oly 45mm 1.8 is $400+ if you can find one. A similar lens receiving accolade like the Nikon 35mm 1.8m, runs less than $200. I can understand there being a premium for the newness of u43 and perhaps increased unit costs of manufacturing these lenses. I had decided to invest in the u43 system over other larger frame systems like APS-C because of the smaller size, and what I perceived to be lesser cost. Is it in fact the case that the long-term cost of investing in u43 lenses at a consumer/amateur level will exceed that of investing in a Nikon or Canon system? Is the image quality of the higher priced (but half the size) u43 lens actually comparable to these Nikon/Canon lenses which cost half the price? I am wondering if I decided I could get by with a larger camera, could I move into a larger frame DSLR system for about the same cost as u43?
