    Using DX setting on D810

    Is there any advantage in using the DX setting in camera vs post process cropping to turn a 200mm lens into 300mm? I would think the resulting IQ would be exactly the same but just want to be sure I am not missing something. I shoot rodeo and crop a lot so just wanted to be sure I am getting the best results.
    Thanks

    I like shooting with the DX setting, for me it helps focusing on the action.
    The DX box lines in the viewfinder helps me concentrate on the subject. Old eyes here need the help. I have not done a comparison between dx and cropped image.

    Would you be using a DX lens? If not, then there really isn't any advantage or difference.

    In DX mode you can get more fps, I believe.

    It is the same as cropping an FX shot, but the file sizes will be much smaller if you shoot in DX mode, which means you can take more photographs and, as Blacktop noted, you can take more shots per second (or at least more shots in a row continuously) because the buffer doesn't fill up as quickly.

    Some cameras actually interpolate in crop modes, creating a larger file than just cutting out pixels. Some digital zoom functions do it very well. I experimented with a moon shot and the Jpeg crop (or 2x digital zoom) gave me a larger file size than the equally cropped RAW file. Not sure if the D810 does that.
