To those with both EM5-II and EM1

I no longer have my EM-1 but my thoughts may be of interest, for my use (primarily macro + studio with a bit of walkabout / landscape ) I prefer the EM-5 mk2

One big downside for me to get out of the way is the grip, if I were judging purely on the ergonomics of that, I would keep the EM-1, which suited my hands much better and just seemed a better bit of design and construction

- battery life is not so good either but not sufficiently degraded as to be a problem for me

So, why the EM-5 mk2?

- the IBIS does seem to work better, particularly when shooting close macro work hand-held (my usual mode of working)

- although it is supposed to be "the same" sensor as that in the EM-5, I believe that something has been improved (maybe in the in-camera processing?) as I get less noise as the ISO increases to 1600 and the images have a cleaner more open look (subjective assessment + comments from club member who have seen images from all three of my EM's 5, 1 and now 5 mk2) Its certainly less noisy than my copy of the EM-1

- I think that focus is faster than the 5 and on a par / maybe a tad faster than the 1

- for my studio / still life work the Hi Res 40mp mode is a real benefit

- although I make only limited use of it the on-board flash is a real improvement with swivel and bounce potential and, I get the impression, a wider focal width (not made enough use for objective comment here)

That's it really, two superb tools and I regret selling all my original kit (a poor call brought on by muscle and joint weakness problems resulting from side-effects from a prescription drug I was taking, now resolved as I have stopped the drug and strength is returning - a magic feeling! ) but it did result in me getting the mk2 which I am finding does everything I need so far
