Hi everyone,
I've just bought a brand new 5D3, and the first thing I did was a sensor check (to verify dead pixels). I used Film Nurture method (https://www.youtube.com/watch?v=TxH35RH2ZlQ).
In my 4-shots test (HERE (https://www.dropbox.com/s/iwmy23nx7h2a5gx/deadpixels.zip?dl=0)) I can see 20 or 30 dead pixels yet at ISO 100, and many more at ISO 800. Anyway, I can see all these dead pixels ONLY in Bridge, while they disappear in ACR. I tried to explain this difference remembering that ACR should have a sort of dead pixels fixer (even if I didn't suppose it was automatic).
So probably Bridge shows the "truth".
At this point I can choose: "mapping" the sensor's dead pixels with the in-camera manual sensor cleaning method (so keeping the camera with its patchy sensor), or returning the camera to Amazon asking for a replacement.
Before taking a decision, I'd like to know your opinions. Is it normal that a brand new camera has that amount of dead pixels? (Moreover, ACR is not in my workflow, so I can't eventually take advantage of its "corrections".)
Thanks in advance for your help.
I think it sounds like an awful amount of dead pixels for a brand new 5d3.
Sadly my almost new 5d3 also showed up with 5-10 hot pixels visible at like 1600. Yours is more extreme so maybe ask for a replacement but I'm not sure you will ever get a perfect one.
