I think the phase detection elements should show up. That is, I suppose they are being used for imaging. If they are not used for imaging, they might be missing, or they might still be there, in the raw channels I'm examining. That would be visible. But if they are shown one way or the other, holding a card in front of half the lens should make the phase detection pixels aimed at that half darker. That's the principle I'm trying to exploit. Like it says in the article jerryy cited, "Fujifilm's system provides a seemingly simple solution - masking-off half of a sensel means it only receives light from one side of the lens. By creating strips of these sensels, half 'looking' one way, half 'looking' the other, the camera gets the two distinct images necessary for phase detection AF." Though, "strips" doesn't sound right, I think they'd just be pairs, one pair at each focus point. Then again, they're talking about tens of thousands of these, not a few hundred (two for each focus point). Still trying to figure out what's up here....

Even with Rawdigger you are not seeing the output from the sensel. You are looking at the data after it has been converted into pixels. Each sensel has a photodiode which converts the amount of light it is exposed to to a voltage. It is an analogue device. This voltage is amplified and applied to an analogue to digital converter in order to get a digital value for that pixel. Two things come from this. Digital cameras are actually analogue at the start of the imaging chain and it is not possible to see the actual photodiode output. Rawdigger is looking at the output data - the only thing it can look at. It is showing you the digital output from the converter. If there is a loss of value associated with a phase detect sensel, this will most likely have been dealt with in the amplifier or during conversion. If that sensel is not being used for imaging at all, then yes, Rawdigger should see it as missing.Strangely, film is digital. Each grain of silver is either there or it is not. It is the number of grains that have been exposed that makes up the tonal value. Digital is analogue and film is digital!

Hello there!!! My name is Mathios Koukakis I am from Greece Crete. I am a semi pro photographer and my favourite gear is Xpro2 and FujifilmXH1 with various lenses I finaly found a place where I can see and discuss also take some inspiration about photography through the eyes of Fuji photographers!!!
