So I've been pondering what to do with my EP1 system. I like it a lot, for the classic 12MP Olympus look to the jpegs and the great ISO 100 performance. The major downside is the quality of the LCD, which makes it nearly useless in my experience for manually focusing. No biggie, I stick with the GX1+LVF2 for my legacy lenses. I would however like to maximize the quality of this particular package, keeping around the same focal length so I can continue to use the VF1 optical viewfinder. I definitely still enjoy the little 17mm pancake, but is there really any reason not to sell it and upgrade to a 20mm f1.7? I also considered the Sigma 19mm, which I assume would still be close enough for the VF1 to work nicely, but it would kill the compactness of the package and wouldn't provide me any larger aperture. Thoughts?
