DPReview released the photography review below on launch day followed by a Q&A and most recently their video review. It sounds like the Olympus OM-D E-M1X is an all-around improvement over the Olympus OM-D EM1 Mark II, but it is disappointing that Olympus didn’t enable 4k 60p since the chip inside is capable. It also should have come with the new EVF that is being used in the Panasonic S1/S1R. It’s possible that Olympus might choose to fix the first issue via firmware update since the camera has two processors, but we will have to wait and see.
