A 8192 by 4320 pixel (DCI 8k) 16-bits per channel image is 34.9 megapixels so if $5000+ is too much for you, then buy the Global Shutter APS-C version of the NEW Wave-8 Global Shutter camera which will get you that same 34.9 megapixels (DCI 8k/4k) at less than $2200 U.S! The Full Frame Version with DCI 8k/4k video/stills around $3500 U.S. AND the Large Sensor Medium Format Global Shutter version of the Wave-8 camera is actually 139.8 megapixel stills (shoots DCI 8K/4k video sampled from the full sensor and 16384 by 8640 pixel stills) and will be around $5700 U.S.
The sensors on the APS-C, Full Frame and MF cameras are video-centric DCI 8K and DCI 16k (MF) resolutions, so it's a NATIVE 1.89 Aspect Ratio at a 60 fps DCI 8k still photos burst rate for ALL THREE CAMERAS and you can record for as long as media is available. You can crop to any other aspect ratio on final export/save! Remember! it's YOUR CHOICE on what YOU WANT to save and export!
