Photographyblog posted their full Olympus E-PL9 Review:
Bottom line, the Olympus PEN E-PL9 is not the most exciting update we’ve seen. Those into video making are best served by the improvements in this latest model. AF speed impresses, it’s good to see the built-in flash return (though sadly see the accessory port removed), wireless connections work a treat and the new graphical interface is fun.
In it’s own right, the Olympus PEN E-PL9 is an excellent entry-level compact-system-camera with more features than most.
The camera has yet still to be announced in the USA.
