    Have been looking for a long time to update the photo camera from my Nikon D810 that has been with me for some years since they were launched. Now I want something a little smoother in size that also has good battery life, full format and with good movie features. When I also drive an a7iii I longed for this and when the price was lowered to 37 990: - I struck with short reflection time.

    Most of my lenses are Nikon and all the flash equipment from Profoto and Nikon have transmitters that fit Nikon. All transmitters and flashes work very well with the Sony cameras, although I am limited to manual mode. This doesn't matter to me as I almost exclusively shoot in manual mode.

    Unfortunately I have no adapter and few lenses that support autofocus when I mainly shoot or shoot products so have no experience of autofocus performance.

    Focus peaking works very well together with zooming into the image to focus. The image files are a clear lift from the Nikon D810, this is mainly due to the large jump in megapixels but the performance at higher ISO is significantly better. Earlier you felt bad when you had to shoot over ISO 640 now I comfortably go up to ISO 1600 or shortly thereafter.

    Top quality and easy to understand menu system after a run-in. It's pretty big.

    Smooth with SD card and great battery life! Highly recommend this one!

    The negative is precisely the filming in my eyes as you are limited to 4K30 and 8 bit. Have previously used RED, Blackmagic etc where you get much nicer movie files. However, the picture is razor-sharp from Sony when sampling from 6K.

    Very nice camera that should be purchased by anyone who wants higher quality and bigger pictures. It remains for me to shoot in 240mpx mode. Many customers love this because they never get enough of high resolution product images.

    Wanted for APS-C mode on the Sony 26 megapixel camera to reduce the number of lenses. The great advantage of Sonyn for my part is that you can program a button for APS-C mode and quickly zoom in 1.5 x. This works surprisingly well in practice. Love this change.
    Uses full format for large contrasts, low light or wide angle. The rest can be run in APS-C format.
    In practical terms, I usually use full format when the wide-angle lens is on and APS-C when the telephoto lens is on.
    The film features I am not at all interested in. If I was interested in filming, this camera would not have been a first choice.

    High resolution requires very sharp lenses. Now there are three very sharp and lightweight lenses at affordable prices (35 / 1.8: 55 / 1.8: 85 / 1.8).

    The menu system has received some criticism, but I think it is unjustified.

    iOS app: Well functioning automatic GPS tagging via bluetooth is the most important thing to me and it works lightning fast.
    The other functions I don't care about, but they don't seem quite as promising. The app has a bad rating on the App store.
    One must "reset network settings" on the iPhone to make it work after upgrading to iOS 13.

    I have been using my copy for a few weeks now, primarily for photographing images and objects. The 240 mpix mode works very well, remotely controlled from the Sony Remote application on Mac (or PC). Fascinating to watch in Remote when the shutter speed is set so far that I can keep up with the imaging - a half pixel offset 16 times actually gives a sharper image and richer colors! The next bottleneck is, of course, the optics - expect you to correct for lens errors in Photoshop Raw and Photoshop, almost no matter how good the lens initially is. If you do the job well, you will be rewarded with pictures that make it possible to create large-scale productions and reproductions with good sharpness. The camera is fast, has good controls, and overall a good look-and-feel. UHS-II is a big step forward for Sony, and the IBIS seems to be doing a good job, alone, and with the lens's built-in stabilizers. The color rendering is good, and together with good contrast range and use of a suitable Panton palette gives it good control over the color flow throughout the production flow. If it were to be slightly deducted from the overall rating, there is some noise in the image when looking down at the pixel level, and that 4K video is "only" in 8 bits (even on the HDMI port) and up to 30 fps. For such an expensive camera, it seems almost incomprehensible by Sony to jolt down such a performance, if that's what they've done, because, in terms of processing, everything should make for a good experience. For recording nature and culture with slow panning and relatively slow motion, it is still a very capable camcorder also with good sharpness, contrast range and color rendering. With suitable adapters it can of course be used with good lenses from manufacturers other than Sony.
