I dont doubt you, personally it doesnt bother me but I understand how it can drive some people crazy. At the end of the day we all will have to make our own decisions on how well the new headsets/comfort kits can mitigate the issue.

Of course, Iâve never denied that. In fact Iâve not even talked about blur. I was just referring to the distortion.
THIS is exactly the reason why I usually NEVER use any other lens than Macro, when it comes to TTL. Taking poor shots with a smartphone or a wide angle lens is just totally confusing and misleading. We have too much of that crap on YouTube already.
All I wanted to show you was the amount of information you get on 4K screens at 20 meter distance.
The first full-frame image was just to show you that I was standing at the same spot taking these 2 images. Although its low quality hand-held shots, it clearly shows something. And in reality that difference is night and day.

@SweViver hello, Poem guy here, my DM ?

Sweet spot is about the area without blur. The sharp area.
Distortion has nothing to do with sweet spot, especially since none of the headset has distortion within 120 FOV.
I will get back to you shortly!

I always understand a âsweet spotâ as a place to be, rather than a place to look at. If an audiophile vocabulary could be used as an analogy, it is a place where you place the eye in order to have a best view (of the image).
Consequently, âhaving a large sweetspotâ means having a lot of leeway in where to place the eye and still get the best image. Small sweetspot means one has to be in the exact place, otherwise it will degrade the experience.
Pimax headsets have very small sweet spot, some none at all.
To what you refer as âan area without blurâ, is basically just that - the area in focus. Please, do not confuse the two.

No. Like Risa just explained, itâs the area where your pupils be to have the best image. And on the pimax the distortion changes when you change your pupil position. Thatâs why people are heavily tweaking their headsets, with foam, with moving it up/down/tilting it even. Itâs actually very hard to find the sweetspot, the spot with the least distortion, on the pimax.

Are you now implying that the curvation (distortion) does NOT happen on the 8k-X as itâs shown in your photos? And that itâs just a byproduct of your phoneâs camera? Thatâs odd cause it exactly happens like that on my 5k+.

But the bending on the picture with out movement is minimal, but if you move your head you see it like when you are drunkâŚ

@SweViver now that the new cable is ready and youâve been testing the 8K X, when do you think it will be ready to ship? Is it still late March/early April 2020? And any updates on the 8K Plus?
The p4k has very little distortion due to the Aspherical lenses. Truthfully you need specialized gear to take proper TTL shots with consistency. But the Distortion mentioned is present due to the curvature & transition from the âyokeâ of the lens to the âwhiteâ(flat). This is where if the Yoke was more square the geowarping would be even less present due the transition being a rise sloping to flat. This I believe was the direction @Neoskynet was talking about. More of a pyramid lens vs a part sphere.
Eyetracking will likely help immensely as StarVR One also has yoke lenses.

It also often results in crack if you drop the phone. 
Now the new p30 pro might do well. Very nice cameras on that phone.

Yes it has OIS too.

Part of the difficulty is the sweet spot can vary from one person to another.
Me for example the sweet spot on Pimax P2 series is quite large. So a combination of face shape & ipd sensitivity. For example only xp eye strain using ipd soft offsets.

I know. Originally thats the correct explanation of sweetspot, as you said.
I have personally always referred sweetspot to the sharp area across your view. I know it might be wrong, but its the way I describe it. Simply the âfully sharp areaâ in front of you before the blur or any distortion appears further outâŚ
And again, within 120 degrees or so, Pimax has no distortion. The objects you see in the first image above is probably 35-40 degrees to the left, which is within 90 FOV of the Pimax. I took the photos with a vertically aligned smartphone. The distortion you see is caused by the distance from the camera to the lens. This optically distorts the image the further away you hold the camera.
And again⌠The curvation starts above 120-130 FOV. What you see on that image is all within or less than 100 FOV.

Way sooner than March. More info coming soon. Cant tell you more at this pointâŚ

In my definition it does not. It is a direct consequence of the optical design. Individual features may make it easier or harder to get into, but the âsweet spotâ alone remains the same, regardless which person becomes its subject.

Then the sweet spot is both large & small then(by what you said how easy one can get into it). For me I can dial the mechanical ipd in & out & maintain good picture. So individual sensitivity or acuteness to stereo3d must be a factor.
The p4k only had soft ipd & largely had no noticeable effect on me.
