Potential amp glow on X-E3

Ok, so this is very very interesting- this issue appears to only occur when using the mechanical shutter. When using the ES the noise is totally clean and even, as it should be. See

Hmm, my example was likely with the ES. Will post an MS lens cap example later today.

Thank you, I appreciate that

These are both with the X-T20 at ISO 12800 pushed five stops AND with the Blacks at +100 in Lightroom. I also get a purple glow along the bottom only with the mechanical shutter (really not sure why). I can say though, having used this sensor for a number of years in many very low light situations, that it has never been a problem in any real world image making.

Mechanical Shutter, ISO 12,800 pushed +5 stops (ISO 409,600) AND with the Blacks at +100

Electronic Shutter, ISO 12,800 pushed +5 stops (ISO 409,600) AND with the Blacks at +100

...and with a couple of graduated filter tweaks your ISO 409,600 shots can still look awesome. Apparently the MS doesn't quite manage perfectly uniform exposure

The top MS shot with some added correction

Very interesting thank you, I am glad that my camera is seemingly not defective, but its a shame I can't return it and get one that doesnt do this

I appreciate you taking the time to do the test for me!

I wonder what it is about the mechanical shutter that makes this happen, and if it happens on newer cameras? I will ask my friend who shoots an XT4 if they can test this too.

These are from the X100V, same settings as before. Noisier, but definitely more uniform...

X100V, Mechanical Shutter

X100V, Electronic Shutter

I'd be curious to see the same test from the X-T3, Although it uses the same sensor, the X100V seems to me to be the slightly better high ISO performer (I owned an X-T3 briefly). Despite the more uniform noise here (at ISO 409,600 equiv. + the black slider at 100)), with less noise and fewer artifacts in real world images, I still give the older X-Trans III sensor the edge for "normal" high ISO shooting
