Wow!! Nice progress, funnel. Although I was quite satisfied with the beta 1.1, as I was mainly interested in Raw and little else (well, that effective focal length
).
I'd give a try to that beta 3, but these days I've used the camera a little and from Raw files this sensor it's quite good. Just to give you an idea, noise at ISO 800 and dynamic range at base ISO it's about the same than Canon S95 and better than Olympus XZ-1. Obviously these are different cameras (those fast lenses...), but I was very impressed.
I have nothing else significant to tell though...
But what a heck of sensor...
Saludos!
