Thanks for the link, useful one.
IMHO:
Looks good at f/0.95, good balance of softness (expected) and resolution, even if just on the E-P2 rather than E-PL1. No obvious border distortions, so this 25mm is good for m4/3. No strong chromatic aberration too at wide open unlike the 50mm f/1.1 (at least in these pics). All dim light shots look fine.
However, daytime (f/2.8 example) and it still has that hazy look, just like the 50mm f/1.1 in daytime.
Resolution-wise overall, can't tell much. I find it average, but most of the time people take better pictures than reviewers, so judgement reserved and best to try oneself when it launches.
Interesting lens for sure in very low light, and 50mm equivalent focal length. I really like that min. focusing distance of 0.170m (6.7 inches)
