I like all types of photography and have carried both a Nikon D800 FF system and 2 OMD bodies for the last 4 years. My current OMD’s are the EM1 and Em5 MK II (backup), and are used mostly for my travel, portrait, non-action events, street and general shooting. I have the 3 Oly f2.8 Pro zooms lenses and 4 Oly Premium f1.8 primes in 12, 17, 25, 75mm plus the 60 macro. A few months ago I made the decision to buy the Nikon D500 as my action, air show, sports and BIF camera over the upcoming EMI MK II, (see this post if interested- New EM1 V2 or Nikon D500? ) Very, very happy with this choice. I mostly use the Nikon D800 for landscape shooting, though I do use the EM1 and the 7-14 f2.8 or 12-40 f2.8 Pro lenses too. The main use for the EM1 is for my portrait work. Having used the 42.5 f1.2 Nocticron lens for over 2 years now, it is just amazing and accounts for about ½ of all my M4/3 photos. Also use the Oly 75mm f1.8 quite a bit too when I have the room. I feel the Nocticron is best lens I have every owned, including over 30 past Nikkors and 4 portrait specific Nikon lenses in 85, 105 and 135mm sizes. I want to upgrade my EM1 body to a 20MP M4/3 camera with dual card slots. While the EMI MKII seems the obvious choice, my interest has been peaked with the new GH5. Yes it is a video-centric camera, and frankly I have almost no interest in video. Despite having a lot of gear, I am a simple shooter, I use the manual mode for almost all portrait work, the S mode for sports action and the A mode for everything else. I use the front/rear dials for aperture and ss changes. This simple style of shooting helps to equalizes out the layout and control differences of the different bodies. What I find is that dedicated buttons for ISO, WB and EC +/- , like both my Nikon bodies have, make shooting so much easier. The EMI, as does the new updated Mk II, has these buried in menus or Fnc buttons and means you have to stop shooting to find the way to make changes. So when I looked at the GH5 for the first time and saw all 3 of these buttons right by the shutter release I was flabbergasted! And the On/Off switch is also right there, meaning a one-hand operation, something else I do not like about the Oly layout and two hands needed to turn it On/Off. But the really important feature I have just learned about is that the GH5 will work with my Nocticron and give me Dual IS! The Noct is already a low light wonder and the added Dual IS could be a big benefit for me. Not having owned a Panasonic M4/3 camera before, I am not at all familiar with the Panasonic system, and would like to hear from others on what might be the plus/minuses of using the GH5 for a stills shooter like myself. I have the original version of the 100-300mm f4-5.6 Pany zoom and I believe that will not work in dual IS, but it still will work with the 5 axis body IS? With regards to future lenses, I am looking at the P/L 12mm f1.4 and the upcoming P/L 8-14mm f2.8-4 zoom, to replace my 7-14mm f2.8 Pro Oly. Don’t think either of these have OIS, but at least the aperture rings will work.
