Vision Pro beats Quest 3 on many specs
BUT one thing the Quest is SOTA in are its lenses: Massive, beautiful, crisp, sharp edge to edge, high FOV (vertical and horizontal), minimal lens glare, with a massive sweet spot

Vision Pro vs Quest 3 Passthrough
IMO, the biggest reason people are underwhelmed with Vision Pro’s Passthrough is likely due to the muted/neutral tone mapping and contrast
I think the Vision Pro’s cameras have higher dynamic range but their tone mapping is really muted.

@DennysKuhnert
I’m guessing this is due to
- hand tracking frame rate being LOWER on AVP (30hz) than Quest
- Passthrough frame rate being higher on AVP (90hz), so it has much lower latency than the AVP hand tracking at 30hz

I realized I never shared any photos/videos of my scanning project of the Khztkonk Monastery, 25km outside of Ani.
So here is a walkthrough! Enjoy
1) The Armenian monastery of Khtzkonk in Digor, formerly Tekor in the Kars district. Locals say the monastery was blown up by Turkish military sometime between 1920-1950. All that’s left is the Saint Sargis church. There are visible ruins of the other churches dotted around.

Here’s what I mean
The vision pro’s facial interface is made out of a mesh material and when you have bright light sources (like the sun), it’s quite noticeable
I noticed it instantly when I first tried it on at the Apple Store (which is typically lit quite bright).

btw, has no one mentioned the light bleeding through Vision Pro's meshy facial interface?
