Canon just announced EOS-1D X Mark III with the ability to capture stills in HEIF format:
“The development of EOS-1D X Mark III is a clear example of Canon’s commitment to pushing the boundaries of innovative imaging products featuring optically excellent technology. The camera will support an all new, Canon-developed, CMOS sensor and DIGIC processor, that will deliver greater image quality, at even higher ISOs, with the ability to capture stills in 10-bit using the HEIF (High Efficiency Image File) file format. HEIF produces wider dynamic range and greater color representation compared to JPEG. The power of 4K resolution brings stories to life – shoot 4K videos including 4K60p with 10-bit 4:2:2 Canon Log internal recording.”
How is the HEIF support in opensource software atm?
This move by canon could potentially be followed by others and render jpg obsolete in a few years.
