Because after seeing swevivers video, I’m really disappointed with fresnel. I know their are some big picture reasons Htc valve and oculus had to make this choice because new users could get turned off I guess by the Tech if they got sick. So in that case blurring the periphrial helps reduce motion sickness. But pimax is dedicated to us who want something more. So I’m really hoping that they don’t use fresnel.
Pimax for 5k & 8k are using some kind of fresnel lenses. But looked great in v2 & v3.
@SweViver will likely agree pimax is doing a great job on lenses.
These are alot more advanced then the Vive lenses & is a complaint that htc didn’t work on improving the lenses in the pro.
I myself didn’t observe lens flaring.
Pimax is using a special fused Fresnel lens in the 8k if I remember correctly. Although it’s not like the lens used in the Htc and Oculus apparently. It seems to have little to no god-rays and the circular artifact you see in on the Htc Vive doesn’t seem to be there. But I might be wrong about some of this information.

After seeing swe’s video, I don’t just dislike fresnel, i downright hate it.

I can see your point, because the down-side is so obvious. But don’t you think that that will have been the same for the Valve and Oculus developers ? And still they chose to go down that path.
But as Alan Yates said, this may very well come down to individual tolerance: if you do not suffer from the immediately less obvious, but apparently more serious downsides, then swapping the lenses may offer a great benefit. However, if you swap the lenses and at some stage notice a growing discomfort, pupil swim, etc., going back to the original lenses is of course possible, but you will risk a slightly less optimized performance if you cannot recalibrate the HMD afterwards.
It would be interesting to see if there is any kind of test available, which shows you if you are likely to suffer from such discomfort or rather not. Is it just the general kind of tolerance a.k.a. VR legs, or is it something more specific one could perhaps test prior to modding a HMD?
Although gear vr lenses is clearer than freshnel lenses, but it fov is 101 and I am not sure how much fov after changing the gear vr lenses to the vive pro.
Wearality is 150 fov and it is freshnel lenses too.
Wearability is a hybrid lens. Will see if i cam find the article/review.
I remeber that baofeng mojing s1 is hybrid, wearality is curve freshnel lenses.

Truth we had a good discussion awhile back. The 4k i beleive used aspherical lenses. Which are marketed for low distortion. The thing to remember is the Vive is still using a first gen fresnel; this is where it was or rather is odd they didn’t invest in refining & improving the lens.
This is where pimax is demonstrating a high level of dilligence in refining the lenses. In the same way your concerned about being potenially part of the 2% that might suffer effects from 10fps less than 90.
While they describe consumer will not likely notice differences in lenses. There will be a small number that may.
Its something that you need the hands on to really know. Like SweViver i saw how beautiful it was at that point of development. & as you know god rays & sde were the first things ppl were looking for. & reports were good.
With the Vive pro & users exoerimenting with gearvr lenses also gives htc or 3rd party to explore offering after market lenses.
No thanks. Pimax will fail 100% if they dont use fresnel lenses. No one is going to buy a headset that has only a chance of not making you sick due to swimming in the vision. Thats why all the high end headsets all use more expensive fresnel lenses. They sacrifice a little bit of visual quality to reliablely be comfortable for everyone to use.
Perhaps we just have to wait a bit - as it was mentioned somewhere, it seems that the Oculus Go will boast next gen lenses which perhaps solve some of the issues the current state of art is being plagued with. It’s a pity that this will not help us/Pimax with the 8K but it gives us hope for the issue as such, in future iterations. Due to the size of the lenses on the 8K a replacement with Go lenses will not make sense either…

Lenses i find the 4k is fine. I have spent hours in quite a few titles. This is where more research needs to be continued.
Fresnel is also very old(of course often old tech can be better thsn new ideas)
Point being while they are using fresnel lenses its premature to make such a presumption. Something new may supplant it or something old.
Ie lcd will never be able to replace the quality plasma offers.
Oddisay is using fresnel lenses as well and this GearVR mod is compared to a sweet spot with oddisays fresnel lenses so this not necessary is bad if is fresnel lenses. The second problem could be is it possible do convex lenses for 200FOV? Pimax 8K have a combination of Fresnel and convex lenses.

Pimax 8k is clearly using fresnel lenses.
You can see the lens flare in their latest video showing “Elite: Dangerous” @ 1:13:

From my experience, wearality has less godray, I understand that the purpose of aspherical lenses of gear vr which replace to vive pro is trying to look the edge clearer.
But dont’ forget that the fov of pimax is 200 and you don’t need to look clear for all of display. You only want wide sweet spot.
Lenses is not used on the same display.

I would settle for 87fps 
no lower though
Plus 90 doesn’t just happen once which everyone knows but doesn’t really think about. Every second is 10 less frames at 80. … a lot. Denser frames adds so soo sooo much prescience for me. And I think many people, they just aren’t aware of it.

Fresnell lenses means less godrays not more, it’s the superior lens if you want clarity and Pimax pretty much has to go with it.
