Cool, thanks for your assesment! There's not a chance in hell that Panasonic will update the 20mm anytime in the near future. As you admit, the 25mm exists. Yes, the FOV is a little different, but they are close enough that the two lenses perform essentially the same function. Both are exactly 2.5mm away from the diagonal length of the micro 4/3 sensor; both can be considered a normal lens. The angle of view going from a 25mm to 20mm is less than 9 degrees difference; that's smaller than the angle of view going from a 20mm to 17mm lens. Plus, the 20mm is sold out pretty much everywhere; they can't make enough of them. What's their incentive to update it then, if people seem to be speaking pretty positively about it with their bank accounts? Also, did you just look at center sharpness, or did you check the borders as well? I'm curious how the 19mm fares there, because while the 20mm is astounding in the center, it quickly falls off to sub-kit level performance as you move outwards.
