Hello
I have this problem I just realise it has been for long time anyone have this problem on the sensor?
 i will see what they will say
quiet expensive 500€ for service check + 900 € for replacement of the filter

How much have you adjusted exposure and contrast? A lot of sensors look like this because they are made in halves.

[thekeko]

have a look closer

[Bo_Dez]

I did. It has obvious flaws, but how much have you adjusted the exposure by and contrast? Most digital has these flaws when you push things extra hard - Which is why I ask?

it's a bit hard to diagnose and help you if you give no information other than a jpg.

we try with other digital back and it's not the same

i can't see that one through the dirt on the sensor and it is not pushed as much as your first image of the 250.

Here is a my old Phase One pushed to very extremes - every digital sensor exhibits this to some degree when pushed hard enough.

here an other screen shot  and it's not extreme at all

If it's showing at normal exposures then you will need to have it looked at.

[thekeko]

it's normal exposure but you can see what happened to the digital back

yeah it seems like either a sensor filter issue of it could be electrical too. I have heard of flash triggers effecting noise, have you tried a different trigger?

[thekeko]

not possible for trigger
