Hi guys,

Just a warning if you want to use filters; watch out for the lens inside; I am not sure how I lost it but the lense is not attached firmly to the black screwed on frame..

Is it good enough to leave the ND4? Any disadvantages?

Thank you

There is no lens or glass by default, it is just a metal ring. Thus all is well with yours!

The original Bezel ring does not contain a lens, it is merely a thread protector, once removed it allows for threading filters onto the camera. I suggest not constantly removing the ND filter(s) after each flight. I leave the one I use the most on and only change it when conditions require.

The ring does not contain a lens, so you are fine, don't worry fly happy.

Put an ND8 on to cover most light conditions and the ND16 for the summer.

It really depends on lighting condition and what you are looking to do.  With that said here in Nevada when the sun it out is is bright so I find I mostly use my ND32.  Sometimes when cloudy I will swap out for the ND16 to allow for the shudder double what the fps is without being overexposed.

Yeah which is quite often here.  And the Nevada sun can be very bright.  Thing is I see that most only ever need a ND16 but with the ND16 I was still needing to use a shutter around 1/120 to 1/160 to get the EV to 0.  Now with the ND32 I can use shutter 1/60 and be at EV 0 to EV-.3 which is great.

Then I'd use the one with the highest number stops so the ND16 - if you experience the need to still increase your shutter more than double your frame rate with that on you may wish to look into getting an ND32.

If you go onto Youtube and type 'using ND filters with Mavic' you can take your pick of about 100 videos to watch on the topic. A good source on this one is Tom from Tom's Tech Time - he's very thorough.

No probs - it’s all about keeping your shutter speed double your frame rate to create motion blur and more cinematic footage without over exposing the image when flying in bright conditions. The brighter the light the stronger the density of the filter needs to be to stop that brightness from hitting the sensor in the camera.

thank you!! so in the MA the shutter should be around 200 double the frame rate if am shooting in 4K 100FPS correct?

The highest frame rate on the Mavic Air in 4K is 30fps if you've selected NTSC over PAL - if using the highest frame rate in 4K your shutter speed should be 1/60th.

Frames are per second - the video recording is the bitrate.
