  • Photography consultation for Sony A7R4

    I recently sold my Canon camera to a Sony series A7R4A with a Sigma 100-400 lens. In the process of using, I feel that there are some gaps between the pictures taken by Canon before. After ensuring that RAW is turned on, the noise of the image is more obvious at low ISO. The dark area of the picture is also too dark, and the overall picture feels like a layer of mist. Could this be because of the 61 million pixels? Have you communicated with friends who use the same camera? Or Sony camera users, there is still a lot to learn.

    The smaller the pixels, the highest the noise,
    The smaller the pixels, the highest the diffraction (at least at large apertures),
    The smaller the pixels, the highest the requirements of lens quality (even some Sony lenses encounter some troubles on 61Mp sensor)
    The smaller the pixels, the highest issues in cursors positions during RAW edition...

    In summary : High definition is much more giving, but much more demanding...

      The high megapixels give me APSC simulation, which is good enough for longer focal lengths, but the detail per pixel is really a tricky issue.

        Do you have some sort of picture styles applied to it? The colors look unnatural to me, so it might be boosting saturation or the shadow detail and that is causing color noise.

          Thank you for your answer, I checked my strategy, and photo creative style is standard, photo style display is turned off, the color space is taken with AdobeRGB, export converted to sRGB after Lightroom.
