Super Macro with microscope objective.
Visible chromatic aberration.

Can only cross on 70mm floating tele sensor and not the HP9 due to slight vignetting.

Came across this. In case anyone looking for a 3rd party 15 ultra case that support the photography kit. Magsafe compatible too but is either the photography kit attached or Magsafe accessories attached. Looks like got skins to apply to the offical case and grip if that's your thing also.

Is this the 0yuan mysterious gift box with the ultra preorder gift last time, on top of the camera kit + redmi tablet + bundle (spotify/youtube subscription, extended warranty, grab and dragon pass voucher)?

I knew someone gonna attempt lol 3D prints a Vivo lens mount for Xiaomi 15U and the Oppo X8U....



Nice that he is sharing the models in public domain.

Nice. We should be able to see some manufacturers soon.

The Vivo Zeiss optical lens has a lens collar with a dovetail quick release plate that looks Arca Swiss compatible, and a metallic rear mount.

Whoever makes the adapter has to make sure it is really solid if someone were to mount it on a tripod.

Interesting sensor size comparison based on focal lengths.

An image sensor is like a bucket, the larger the sensor, the larger the bucket diameter.
Light photons are like rain drops, the larger the bucket diameter the more water can be collected.
Amount of water collected is akin to information collected by the scene you are capturing.
Compounded by noise in which smaller sensors will suffer poorer signal to noise ratio, larger sensors better SNR.

While there can be slight generational changes like improved microlens arrays, special high gain circuitries etc, end of the day if not a huge multi generational difference the image sensor size still has the biggest impact in a well exposed photo.

All else equal, the Vivo x200 ultra should be especially strong at the 13/14mm end, hopefully next XM iterations can have an 818 or similar sized sensor for ultrawide, keep the 1 inch preferrably at around 28-35mm with aperture control :s13:, and maybe a larger floating telephoto macro sensor.

there is a limit to optical physics yeah.. silicon can shrink but how much sand can u pound into glass?

The greatest leap in recent decades has been computational photography, stacking and processing tens if not ?hundreds of photos in one click back end to produce one photo. Pretty demanding on fast processors and fast sensor readout. But hitting a limit.

Recent yrs Ai thrown into the mix but very demanding on processor, and current mobile processor not powerful enough to create ultra realistic stable diffusion level enhancement.

Alot of tiny sensor phones are doing a heavy imbal reliance on Ai probably because it drives cost price per unit down.

I believe hardware and software should walk in tandem.

Good that there are phone manufacturers trying to go neck in neck on improving the physical camera module(s) instead of the Ai way for a smaller savvy crowd.
