Excessive default/auto cropping vs Lens Correction

    Hi,
    unfortunately I don't own or know your camera so I'm not able to reproduce or identify clearly your issue. But it sounds similar to what has been noticed also for example on the Sony RX100 when the corresponding lens correction steps in. Looking an image in the crop tool at the short FL settings it seems that the correction chops off just too much of the image. But on closer inspection one will find that the pixel count of the corrected image is exactly the pixel count informed by Sony in the camera's documentation.

    In other words, optically and from the original RAW data, the camera (lens) actually takes a larger image than the "paper" 28mm eq. wide (about 26-26,5mm) and this data is then corrected for the 28mm eq. output. This is the same or a similar process which happens in the in-camera processing / correction when an OOC JPG is generated.

    Now in C1 the user simply can use (accept) the correction. Or he/she can make use of the outer parts (which by the "suggested" correction would be chopped off) by changing the crop or the ratio or both. This way it's possible to create an image with a larger pixel count than in the papers and/or with an adjusted crop which makes use of the wider view (possibly at a small toll though which may be some optical imperfections towards the borders / corners which are the original reason for the correction).

    So what seems to be rigid in your description might be also in your case user adjustable to your needs and liking, being the "correction" or "crop" more a suggestion than an imposition. Hope this helps.

    I also use an RX100 and find the pre-cropping to be useless and annoying. I have to manually change every image I process to remove the crop. I crop at the time of printing where there will be different ratios depending on the print size. I also use the extra often for where the canvas wraps around the frame. I have never had a use for the suggested crop, even if it is the same as the Sony jpeg in camera processing. If I wanted in camera processing I wouldn't use RAW.

    I could see that even Lightroom crops the image a little bit, but it consistently leaves less cropping than C1 (but I found after this that I cannot disable Lens Correction in Lightroom).

    If I compared the RAW to OOC JPEG in C1, the cropping is different to OOC JPEG.
    If I compared the RAW to OOC JPEG in Lightroom, the cropping is the same for both the RAW and OOC JPEG (which I assumed would be captured on the viewfinder during capture).

    I hope you could download the RAW and OOC JPEG from Dropbox from this links:

    Have the very same problem even for manual lens distortion correction.
