In Topic: Red filters for GH4

Ah, missed the limit on the wide angle on the adapter

Again, personal choice, but I wouldn't be too bothered by trying to retro fit a back filter if it means using tape etc... Too much potential for gunk near the sensor and owns workings for my liking.

Another option would be to fit a filter step up ring to the outside of the lens hood, then fit a filter to that. Provided that the adapter ring ding sit proud of the lens hood, you wouldn't get any vignette etc, although you would need to ensure the step up ring fitted inside the done port aperture.

I wrote to Alex and he replied that he is not sure none of his rear lens filters would fit in the  Pana 7-14mm. Let's see if someone comes up with a solution...

 

 

How about this?

I don't really care so much about the technical reasons of how and why, just want to know if my goal is to have the best possible edited footage in HD,  is it better to record in camera 4k or HD ?  Not sure if it matters, but I am talking about a Sony A7s ii, which excels in low light and low noise.

As per my suggestion to Etc, I'd personally say record in HD. Everything you may gain from super sampling down from 4K will be more than lost by the relatively higher compression (compared to HD) that onboard on the A7s uses.

If however you were pushing out uncompressed to an external recorder, 4K to HD wins by a mile
