So, with HDSLRs becoming so affordable, some interesting options come up, like sub $2K rig that can really shoot decent video. Two very popular options are the GH4 from Panasonic and the OM-D E-M5II from Olympus, each with its their pros and cons. One notable feature of the E-M5mkII is its 5 Axis stabilization. And if you are shooting lots of hand held-on the move footage, this may be a deciding factor for you. The team at panophoto put the two cameras on a place and gave them a run.
Results are pretty interesting, especially considering that the Panasonic is mounted with a stabilized 12-35mm f2.8 OIS lens. The stabilization comparison between the two camera heavily leans towards the M5. Almost to the point where it can compete with a 3 axis gimbal if you are on a very tight budget.
with the E-M5 Mark II costing around $1,000 it is definitely a cheaper (and smaller and lighter) than a 3 axis gimbal.
The team at panophoto does mention two significant drawbacks with the MD-5 compared to the GH4, the first one is that the image quality on the MD-5 was not as good and it was especially noticeable when you picked a still image out of the movie. The other drawback was the short battery life.
