Olympus OM-D EM-1 Mark II - 4k Video and More Shooting

We've had some more shooting time with the EM1 Mark II stills and some 4k video.

Auto Focus Revisited

I tried testing out the different modes shooting model trains.  I'm still learning the way that the AF modes function.   The single point C-AF worked as one would expect and was the most successful tracking method for me.  I believe that C-AF + Tracking might be better than the previous EM1.1.

The Cross Type and 3x3 block of focus points locked quickly, but there was a problem.  Unlike the way that Nikon cameras work with these kinds of groups AF points, you cannot select the main focus point.  The camera decides which AF point is main within the group you selected.  I often had issues with a moving subject not in focus because the camera picked a focus point below or behind the main subject.

What I would have liked to have seen was, a la Nikon, that the points around the main are used to help the C-AF more accurately track your subject.  I'm going to continue to test the AF types, but my guess is  that the issues are partly mine (lack of knowledge and improper technique) and the camera trying to find the most contrasty part of the scene under the focusing grid.

An example can be found in the images above of the green train.  In Cross or 3x3 grid mode, the camera would select an AF point either below the train on the track or the green body, even though the center of the focus groups were on the front of the train at the face.

Video

Did a more serious set of video shoots in the Cinema 4k Mode.  This was for a news blog I do called Visual Ohio.

Settings were 1/30, f/4, ISO 800.  "Flat" profile with post processing done in Premiere Elements 14.
I would lock focus and then record my shots.



I found the camera a pleasure to work with in video mode.  The IBIS and the 12-40/2.8 PRO were a great combination for capturing the subject above.    Panning was smooth and effective.

Bottom Line:
The EM1 Mark II continues to be a pleasure to work with.  The stills and video performance are great.  I will continue to work with the
