    Hi Guys,

    I did a similar exercise for the Terra a year ago so I decided to see how Mavo LF compared and it seems it follows similar pattern (Dual ISO) except one extra row. The blue shows where the ISO would have the lowest noise level at that HL setting. I’m assuming that comes with a price for example diminished DR? Yellow shows what I would guess to be the ISO setting with highest DR at that particular HL setting, interestingly enough at 4.3HL the yellow shade falls on ISOs 800 and 5120 respectively. Red is for where the noise is the highest, etcetera. Anyways, I am a Mechanical Engineer not an Electrical Engineer so if one of you guys with the right set of skills and the right equipment care to confirm or correct my findings that would be cool. Cheers!

    Here is the one I did for Terra 4K over a year ago…

    My guess is that Mavo LF dual 800/5120 ISO switches at 1600 (not at 2000). Whilst for the Terra 4K it switches at 1280 as advertised but then my guess it is dual 640/3200 ISO (not 800/3200 ISO). Cheers!

    interesting!
    Do you have any visual test footage about this? I’m trying to understand better this function but I cannot find many information around!

    Hello Gualbert.

    Very interesting, thanks for the chart. So with intention to get the most dynamic range from my terra 4k, one should use the 3.6 HS@ISO 400, 4.3@ISO640 and 4.6@ISO800.

    Did you get to measure which ISO  setting gets the most DR out of the Terra? I guess 800, but what were your findings?

     

    Thanks, P

    Sorry for the late reply. Corona has Asia in a rush! Yes, according to my “crude” tests you may get optimum “mid-point” DR with ISO 640 @4.3 HLS which is kind of weird as supposedly the Native ISO for the T4K is 800/3200. Again, I do not own the proper equipment for this and all I can say is that I “eyeballed” the results based on performance and perceived noise. I do not own the T4K anymore so I cannot perform follow up tests as I traded it in for the MLF. Cheers!
