It’s summer time and I guess some 43rumors readers are divers. So you may look at the new double underwater test at Thedigitalshootout. They reviewed both the GX1 (here is the review) and the E-M5 (here is the review).
I live in the middle of the mountains so I am the wrong person when it comes to talk about what’s good or not about the underwater performance. Anyway, I trust the reviewer when he writes that the “E-M5 in the Nauticam housing is hands down the most sophisticated and highest performing mirrorless camera you can take underwater today.” and the “GX1 in the NA-GX1 is so brilliant… shooting performance is great, and the image quality rivals SLRs at 3 times its price.“.
For US readers: The Silver E-M5 kit is finally in Stock at Amazon (Click here).
