The Narrowband Channel | Noise Battle of the EM1X vs Em1 Mk3 @TheNarrowbandChannel | Uploaded July 2021 | Updated October 2024, 22 hours ago.
This video is a battle between the Em1x and Em1 Mk3. These two cameras are at the top of the Olympus product portfolio. Many often call the Em1 Mk3 a miniaturized version of the Em1x, however my own experience with the camera has demonstrated that it is something more.
Now with one has more noise? Let's see the tests.
Bellow are results pulled from ASTAP. If you want to try this software for yourself it is free. Here is a link to get you started. hnsky.org/astap.htm
EM1X 240s
x̄ : 238.13 (sigma-clip iterations=5)
x̃ : 239
Mo : 236
σ : 12.66 (sigma-clip iterations=5)
σ_2: 10.97
mad: 9
m : 132
M : 4095 (169 x)
≥64E3 : 0
Vignetting [Mo corners/Mo]: -6%
Bit depth data: 12
EM1 Mk3 240s
x̄ : 220.34 (sigma-clip iterations=5)
x̃ : 222
Mo : 220
σ : 12.96 (sigma-clip iterations=5)
σ_2: 11.91
mad: 10
m : 125
M : 4095 (210 x)
≥64E3 : 0
Vignetting [Mo corners/Mo]: -4%
Bit depth data: 12
Legend:
x̄ = mean background | x̃ = median background | Mo = mode or most common pixel value or peak histogram, so the best estimate for the background mean value | σ = standard deviation background using mean and sigma clipping| σ_2 = standard deviation background using values below Mo only | mad = median absolute deviation | m = minimum value image | M = maximum value image | ≥64E3 = number of values equal or above 64000
