I stepped into the realm of Micro 4/3 from Dslr's solely to take advantage of the portability, sacrificing the highest possible image quality for the ability & ease of having my camera with me ALL the time. My thought was that many great pictures far outweighed a few awesome pictures(which I could still get with my Dslr.) The progression from OMD-EM5 might naturally have been to OMD-EM1 eventually leading to this mark ll. But, I have come to the conclusion that this camera is not the portable M4/3 camera that the first EM5 was. While Full Frame and APS-C sensor cameras have been getting smaller and lighter, the Olympus M4/3's have been getting larger especially if you couple them with any of the new pro series lenses. I returned this camera because when it was sitting on my desk next to my Pentax K3 it was about the same size. Yes its a great camera, the most capable M4/3 yet. Its very versatile and fast focusing with somewhat better resolution than the previous 16mp version. But, it is no longer extremely portable, definitely not light and pocket-able like my original EM5. I don't really shoot video(the files are just too big to store) and I am not one to lug around a lot of heavy pro lenses - mostly just fast primes. On some occasions I do take landscape photos but a full frame camera is better at capturing the detail, depth of field and subtle qualities of light and color. So the EM1 ll has now developed into a camera that doesn't fit my needs anymore. In turn, I purchased a Pen F for half the amount. it doesn't have a weather sealed body and the new TruePic™ VIII Dual Quad Core Processor, and obviously doesn't shoot as fast - BUT it has the same 20mp sensor AND it's light and portable like my original EM5. I believe that the M4/3 sensor has reached its image quality limit, and my partner camera to my Pen-F will be have a full frame sensor because there are many quality small versions to choose from. If Olympus weather seals the Pen F ll along with adding the Dual Quad Core Processor and resolving a few manual dial design issues(I know if, if, if) But, my point is that I am sure I won't be the only one to head back to the smaller camera for the sake of portability. For now, I am happy that there was another option since I am invested in the M 4/3 lenses.
