A recent OM-D E-M5 Mark II review by Andrew Reid from EOSHD.com (read here) has stated that "Then for a filmmaker it all comes collapsing down like a house of cards. Not only is video quality downright amateurish by 2015 standards, it’s worse than the E-M1. It’s softer and suffers from much more severe moire & aliasing."
I am no video expert, I am merely a photography enthusiast, so I am setting my boundaries here before commenting further in this topic. I will not make any conclusions on whether the E-M5 Mark II is on par with the so-called 2015 standards, that is something I am not qualified to do. However, I was shocked to hear that the video output of the E-M5 Mark II is softer, and suffers more severe moire and aliasing in comparison to the older E-M1.
There is one thing I can do, since I have access to BOTH E-M1 and E-M5 Mark II. I will make my comments on the "softer output". I fitted both cameras with M.Zuiko 25mm F1.8, recorded video at 1080 30p (since E-M1 is fixed to this), exposure was manual and standardized and focusing was painfully ensured to be dead on accurate. Both tests were done hand-held, with 5-Axis Image Stabilization on. I then cropped the video frame images and did side by side comparison.
Here are my findings:
On the left, E-M5 Mark II, on the right E-M1
1/60sec, F2.8, ISO400. Focus was set on the face.
1/100sec, F2.8, ISO400. Focus was set on the front dial
It does not take a video expert to see that E-M5 Mark II is producing noticeably sharper video output than the E-M1. And, not shockingly, better dynamic range, and highlight retention.
I am not here to discredit Andrew from EOSHD, he is obviously more knowledgeable and experienced when it comes to video stuff. I am merely just doing my own comparison, out of curiosity after reading the EOSHD review and perhaps some of you may find this quick comparison useful. After all, E-M5 Mark II is already out in the market. For those of you who own both E-M5 Mark II and E-M1, please do your own comparison and we shall see a collective conclusion!
