50.000 ISO problem with CL

Odd! I get it, too. I shot two frames, the first using the regular shutter at 1/8000s and ISO 50,000 and the other using the electronic shutter at 1/25,000 and ISO 50,000. I imported them into Lightroom and upped the contrast to +100 and the exposure to +2.00. The regular shutter showed the same artifact. The electronic shutter didn't show it. Moreover, I also have experienced this effect with my Oly OMD EM-1's at high ISO. I recall researching it, and folks called it "amp glow.," caused by heat from nearby electronic elements. I don't understand, however, why it would only affect the mechanical shutter.....

I had it on my Sony a7S at very high ISO's.

If I ever need ISO 50,000 then I will deal with the issue, should it arise, at that time.

I have lived 55 years on this earth and thus far have never needed to shoot at 50,000 ISO.

I do understand everyone's needs are different.

Crack on.

I get similar results at 50000iso or sometimes 25000iso. This is at f8 in dark lighting.

Yea. I checked this result with another CL in Leica Gallery. I think this is genetic problem of CL. 

 

And btw, of course I never use 50.000 ISO but I just suspected about light leak of lens mount. So no problem

Just had time to go back into my LR catalog. This is handheld in moonlight ISO 80,000/RAW LR +2EV when I had an a7S. Was able to clean up the purple pretty good in LR, but not ideal.
