Would be great to add a new recording mode at 50fps, in theory this camera can do 50fps slightly cropped almost 1.1x, something like 5456x3069, because there's no high resolution 16:9 50fps mode, not even a DCI at that frame rate.
5820x3070 would be another great option to have.

I think this would be a wonderful addition. You should probably email customer service with this suggestion.

I think you’ll find that BMD may prefer to have the recording dimensions be divisible by 8. Your x-axis is, but the y-axis is not. Just find the nearest 16:9 or 17:9 aspect ratio that meets this criteria.

For example:
5504x3096 or 5376x3024 for 16:9 and
5848x3096 or 5712x3024 for 17:9 aspect ratio.

Of these options, given the goal would be a 4K/UHD delivery, the 5848x3096 17:9 and 5504x 3096 16:9 may be the best options to deliver the best colour.

3072 is the height of 4K super35 4:3, we don't know if it's the limit of 50fps, but 3096 of course would be slightly better.

For 17:9 then suggest 5824x3072 as recording format which in post would be extremely close to DCI aspect ratio of 1.8962962…

For 16:9, the 5456x3072 would be very close with aspect ratio 1.776.

The truth appears to be none of these combinations are standards as perfect ratios for DCI and 16:9.
