My E-M1 has replaced the original E-M5 since acquisition over a year ago. The E-M5 has become a backup with only occasional use. Ten reasons why it is not used as much and why I believe the new MKII, ordered today with the 25 f1.8, will change this are: 1. Improved camera ergonomics. The E-M5, used as a 2nd camera alongside the E-M1, was somewhat cumbersome to use due to the different control layout, as the E-M1 is a better layout. The improved layout of the E-M5 MKII is a lot closer to the E-MI and resolves a lot of the confusion. 2. I want to learn to shoot video. The E-M5 Mk II is vastly superior in video to either of my OMD’s and I might as well start with the best. Besides all the added frame rates, OMD Movie will allow for instant video clips when shooting stills without having to stop and use a tripod. 3. Fast 81 point AF. This is a biggie… I shoot about 60% portrait mode and having the AF points at the upper and lower end of the viewfinder is a big timesaver for me. (As will the ability to angle the rear screen in the portrait mode vertically.) The AF on the E-M1 was much improved over the 35 point AF in the E-M5, and continues to refine with firmware updates - Thanks Olympus! 4. 1/8000 shutter speed. Needed for my outdoor work with models. The 1/16,000 electronic shutter could help too, but not with flash it seems, due to the dismal 1/20 sync speed limit. (Hope the sync speed limit is addressed in the first firmware update). 5. The Hi-Res 64MP raw mode. Really looking forward to this for my landscape photography. The hi-res files might be able to answer that pressing question about which is better at 12mm…the 12mm f2 or the 12-40mm f2.8. We already know which is better at f2… 6. Better EVF with improved stabilized view and image stabilization. Half press of shutter gives stabilized view and shifting compensation, neither OMD I have does this. Looking to use for shooting handheld macro with the 60mm f2.8 and (hopefully) in conjunction with #7. 7. Focus peaking on my OMD’s is not so good with my MF Nikkor lenses. This feature appears workable now with the E-M5 Mk II. 8. PC port. E-M1 works with my manual flash systems and ring flash, which the E-M5 could only partially do (no ring flash) because it lacked a PC port. Oly was really aiming at the studio photogs here and did the right thing by adding this small, but useful item (for me anyways). 9. Built in Wi-Fi with the E-M1 is now on the E-M5 MKII. Most shoots I upload to my iPad and find this very useful when shooting. The talent loves it. 10. Silent mode. 11-Bonus. The battery part of my existing E-M5 grip works with the new version horizontal part. Ordered the HLD-8G grip with the camera and saved $150. Again, thanks Olympus! The E-M5 II will no longer just be a backup, but an active 2nd body for my shoots. Most likely the 12-40 Pro f2.8 or 17/25mm f1.8 will be mounted on the E-M5 MKII and the E-M1 will switch between the P/Leica 42.5 f1.2 and M.Zuiko 75mm f1.8. PS, Not knocking the original E-M5, it was a breakthrough. Just that for what I shoot, the E-M1 was a much better camera for me. Here’s hoping the E-M5 MKII is the same.
