The Redmi K90 Max runs a dual rear camera setup built around a 50MP OmniVision 800 LightHunter sensor that resolves images at 8160 x 6144 pixels  the LightHunter branding refers to OmniVision’s larger pixel architecture designed specifically for better light gathering,

which in practical terms means the main camera should hold up reasonably well in mixed and lower light conditions rather than falling apart the moment you step indoors.

The secondary 8MP lens handles the telephoto side with 5x optical zoom, giving you genuine reach for distant subjects without the quality collapse that pure digital zoom delivers, and the 20x digital zoom extends that range further for reference shots though detail naturally softens at that extreme end.

Video recording is a genuine strength here  8K at 30fps sits at the top of the capability list for those who need maximum resolution footage, while 4K at up to 60fps covers most practical content creation needs,

and the slow motion options stretch all the way to 960fps at 1080p which is genuinely useful for sports, action, and creative video work.

Xiaomi Redmi K90 Max with 20MP front camera uses an OmniVision OV32D sensor and resolves selfies at 5184 x 3888 pixels, which gives you enough detail and cropping flexibility that selfies look sharp and natural in good lighting rather than the soft, over-processed look that cheaper front sensors produce.

The dual camera system is honest and focused two properly specced cameras doing their jobs well rather than a third or fourth lens added purely to inflate the spec sheet, and for most daily photography and video needs that focused approach tends to produce more consistent results.
