Digitalcamerainfo tested the new Olympus E-PL2. It’s a very long review so be sure to have enough time to read it all! They also compared the E-PL2 with the older E-PL1 and yes there seems to be a difference between the two cameras: “Our tests so far show that the color performance of the E-PL2 is relatively unchanged, but the noise performance seems to have been improved slightly.”
A first short user report has been written inside the “Just bought Olympus E-PL2!!! WOW! oh WOW!” forum post at Serious compacts. The title says it all
And to conclude, dcresource posted a bunch of new test shots taken with the E-PL2.
