Mavic 4 Pro / D-Log ISO Limitation

[Greg Peter]

Dear amazing community ,
I don’t know if this has been discussed, please forgive me if it has. I am new to. D-log.

I just found out today that you can get lowest to 400 ISO when in D-log.

To be honest, I really don’t understand why.

But if I keep the 180 rule, and if I keep the advice from one of the persons that I learned from this forum, to keep the aperture between 2.5 and 3 max , I have only the ND filter to play with. So that means that in bright sun during the day for example in Greece I’ll be shooting in 32 or 60 4ND. ?

My exposure from what I understand needs to be at 0, or maybe slightly less -0.3 or so

Can you kind people provide me with some advice on what you think I should try?

But I must say, I’m very shocked and I don’t understand why you cannot go down to 100 iso

Best
Greg

I can't advise on D-log but I think the Mavic 3 had the same liimits:

The point of log is to capture more dynamic range, and to do that the sensor must be working in a certain optimal range. Bringing it down to 100 would wipe much of the benefit.
Some big cameras actually require 800 or even 3000 for max D/R in log...
