I agree with you,
It looks like many people doesn't know the meaning of f1.7 in aperture:
For a given exposure, where Air2s with f2.8 needs ISO 1600, a Mini3 needs about ISO600, or in time, where Air2s needs 1/60s exposure time to get the right exposure, with Mini3 needs about 1/200 to get same exposure, which means it is out of right exposure time to do a ritght 180º video rule if recording at 30fps.
I don't understand the movement of PolarPro or Freewell, but at least freewell have wider range of ND filters. PolarPro looks out of the right range.
I writed them asking about it but the answer was an escalation.
In other hand, ND256 looks a bit too high, but you can use a higher ISO and get the right exposure time, and as you can see, in the last review of Philip Bloom, ND256 does not seem too high at all. |
