I am stuck between two choices as I am new to photography and I am hobbyist and I wish to learn and then earn Part time income with Photography (which is not easy but...).
I am really like the compactness of m4 third cameras.
I will usually do small videos 40% and 60% Still.
I also have plan for stock footage.
Some portrait work.
Some kids videos for YouTube etc.
Please guide me and other thing is I want 4k as well.
IMHO, you want a zoom lens, or at least several other prime lenses as well as the 42.5mm f/1.2. The 42.5mm (or Olympus 45mm) is a killer portrait lens if you are doing formal portraits where you can control the distance between the photographer and the subject. It is also useful to record single artist performances from the audience if you can control where you sit in the audience.
However, you won't be able to shoot anything else because you want a smaller focal length for shooting in normal sized rooms.
A commercial photographer that I follow (Kirk Tuck) tends to favor the Olympus 12-100mm f/4 lens as it gives him most of the focal lengths that he needs (Kirk seems to have gone to 50% video, 50% stills). He did need to add the Olympus 40-150mm f/2.8 for his formal theater work, but the 12-100mm allowed him to not switch lenses for the majority of his work. Kirk seems to bounce from camera system to camera system. He bought a G85, and now has upgraded to the GH5:
I don't have the E-m1 mark II, just the E-m1 mark I and G85. I shoot video (1080p) 2 weekends a year, and the G85 is now my go-to camera for video. I had been using JVC camcorders before, but the G85 blows them away.
Now, I've been shooting Olympus for since 2001, and I'm more tuned towards Olympus for stills, but the G85 is a great camera for stills as well.
I will note that the reason I bought the G85 over the E-m1 mark II is I need to wear polarized sunglasses when I'm outside, and the E-m5/E-m1 bodies use a viewfinder using TFT lcd technology, while the Panasonic G85 uses an OLED technology. The TFT technology has polarization effects when you shoot in landscape (horizontal) orientation, and the OLED does not have any effects.
However, I have a few issues with the G85 that Olympus does better. If I was shooting Panasonic only, I would probably spend more time adjusting my shooting behavior to the camera.
