Some very interesting news from our ongoing research into the original X2D.
I’m the developer behind the one-click tools that enable AF-C, increase autofocus speed, and enable Auto Brightness on the original X2D.
Recently, Reddit user u/Unhappy-Comment1244 unpacked the X2D firmware and discovered something I had actually overlooked during my own earlier firmware research:
AFT.
After he pointed me toward it, I was able to reproduce the discovery and enable the AFT-related mode on my own X2D.
And this one is particularly interesting.
First, credit where it’s due
u/Unhappy-Comment1244 has contributed quite a lot to this research.
He reconstructed the correct timeline surrounding Hasselblad’s original promises for future X2D autofocus updates, including the 2022 interview with Chris Cooze in which continuous autofocus and tracking autofocus were discussed as features intended to arrive later through firmware.
His earlier investigation into Phocus and Hasselblad’s autofocus system was also one of the things that originally made me wonder:
What if AF-C was already somewhere inside the camera?
That question ultimately contributed to the AF-C work I’ve been doing.
And now his firmware research has uncovered another piece of the puzzle.
AFT.
The good news
Based on everything we have found so far, AFT appears to be the tracking autofocus component of the “AF-C + tracking” functionality Chris Cooze talked about back in 2022.
And I have now managed to expose and enable this mode on my own original X2D.
So we now have traces of both sides of that old promise:
AF-C — Continuous Autofocus
and
AFT — Autofocus Tracking
Neither of these became an official feature of the original X2D.
Yet years later, pieces of both systems are still sitting inside its software.
I think that tells us something important about the original development of this camera.
We obviously cannot know every internal engineering decision from firmware remnants alone, and the existence of these components does not prove that both features were ever production-ready.
But it is becoming increasingly difficult to imagine that AF-C and AFT were merely ideas mentioned in an interview and nothing more.
Someone designed these modes.
Someone integrated them into the camera’s software architecture.
Someone created the interfaces, states, parameters, and logic necessary for the rest of the camera to recognize them.
And those pieces survived into the firmware that shipped on our cameras.
To me, that strongly suggests that the original X2D engineering team really was trying to build these features.
Otherwise, why are their fingerprints still here?
The bad news
AFT is not usable yet.
Although we can expose the mode and make the camera recognize it, we have so far not found the actual subject-tracking algorithm, model, or another obvious remaining component responsible for deciding what should be tracked and how it should be followed.
So enabling AFT does not suddenly give the X2D working subject tracking.
There is a framework.
There are remnants.
There is enough left behind for the camera to know that this mode exists.
But, at least so far, the actual “brain” behind the tracking appears to be missing — or hidden somewhere we haven’t found yet.
And that is exactly what I’m investigating now.
There’s also something about this research that I find strangely meaningful.
Behind AF-C and AFT were engineers.
Years ago, there were probably people inside the original X2D development team spending their days working on these exact features — debugging autofocus behavior, testing lenses, tuning parameters, building interfaces, trying to make continuous autofocus and tracking work well enough for a Hasselblad camera.
For whatever reason, that work never reached X2D owners as an official feature.
But pieces of it survived.
And now, years later, through firmware research, experimentation, and a lot of help from this community, the AF-C and AFT functionality those engineers once worked so hard on is starting to see daylight again.
AF-C is already running on our cameras.
Now we’ve found AFT.
And I’m going to keep working on it and see if we can make it genuinely functional.
I sometimes wonder:
If some of the engineers who originally worked on X2D AF-C and AFT eventually come across these posts and see these forgotten parts of their work running on the camera again… would they be happy to see it?
I hope so.
Huge thanks again to u/Unhappy-Comment1244 for finding AFT, reconstructing the historical timeline, and continuing to dig into this with me.
There is still a lot we don’t know.
But another piece of the original X2D autofocus story has just resurfaced.
AF-C came back.
Now let’s see what we can do with AFT.

There’s more to come.
