I don't know if I posted here, but I got the E-520 back from Olympus, with the final firmware. I've been using it a lot! I also got the Zuiko Digital 18-180mm lens from them. Below is a photo I took yesterday with the E-520 and the 12-60mm SWD lens at ISO 200. It was shot RAW and converted with Olympus Studio 2 software then I applied a very minimal levels adjustment in Photoshop to punch up the contrast.
I've been posting photos from the updated E-520 for a week or so now. You can browse all E-520 photos here:
