Sony has just officially announced the new Sony a7 IV. It uses the full-frame 33MP Exmor R back-illuminated CMOS sensor delivering outstanding speed and superb image quality. The use of copper wiring contributes to higher transmission speeds and faster AD (analog to digital) conversion, while fast sensor readout enables 10-bit 4:2:2 4K recording up to 60p. The sensor also provides improved color reproducibility, low-noise performance at all sensitivities, 15+stop dynamic range and increased AF (autofocus) speed and precision performance. Experience improved levels of color gradation and detail rendering as well as soft, natural-looking human skin texture.
