GH4 or EM5MK2, What accompany's the A7S best? In: Cameras Posted February 14, 2015 Low light sucks on GH4 - way too much moving noise with high ISOs, basically anything shot with out good light, pretty much sucks. Looking into getting a metabones speedbooster in hopes of it helping in this regard. But if you shoot in good light or outside it can be awesome. Also be careful taking advise on setting up the Profiles from Internet sources. Some are way off the mark. Cinelike D for post - Cinelike V for baked in look. Stay clear of bringing up shadows or master pedestal on camera - in most cases it just creates noise unless you have lots of light.Pans with 4k and punch ins - may not be the same as doing them physically but if you shoot with 4k sometimes things get in the shot you don't want - say if you were shooting a wedding and a wedding photographer walks into your shot. Saves the day when you can punch in - say to the bride in this case and then punch back out once the photographer is out of the shot. It is also the only way besides automation to get movement ( panning - zoom etc. ) in shots where the camera is unmanned or unwomanend. Focus is a consideration also - Can't fix Focus in post. So low light can be achieved on the GH4 but only when the Fstop is wide open which makes it even harder to keep things in focus. Dave Dougdale has a GH4 vs A7s video - the lack of Focus memory on the Sony is probably the only thing holding me back from purchasing a A7s. I have a focus puller on a GH4 that works really well - I can mark a focus then point somewhere else - focus - shoot pan back and pull the focus to my mark and it works perfectly. From what I can see on Dave Dougdales review the Sony is easy to focus with peaking but - maneuvers as I described above don't seem to work. Haven't tried this myself just going by his review. Would be interested to know if that is true or not.
