I have this somewhat obscene doubt that I think a lot of people here must have analyzed. I switched to m43 from Pentax for both size and what I thought was an exaggerated increase in premium lens prices. Now, I am on a budget but this was the first time that I wanted to consider paying more for lenses than camera body. I bought a GX1 and a PL25 and O45. On Pentax I used a K-7 and FA50 1.4. We all know that premium lenses hold their value better over time. My question is, are the m43 primes stellar lenses? In the sense that some full frame oldies are? The question stems from recently noticing that good full frame glass is perhaps only a few hundred dollars more in instances. Or maybe I'm really trying to compare a $500 lens to Leica glass and that's not going to ever be fair. Just in case, I'm not thinking of the value of these items for more than 5 to 10 years. Just wanted a good quality/price comparison.
