    Occasionally used it but really prefer more traditional methods of getting sharp focus

    Focus stacking. is certainly something I have considered using. But I have always regarded it a more important to people specialising in macro photography, more than for almost any other field. Though it has specialist applications for most subjects that do not involve movement. It is certainly useful in Landscape work and for Architecture, but has its limitations, especially with included objects like leaves and plants that move in the wind. These would prove difficult for much of the year in the UK.

    Stacking is a facility I have in the software I use for stitching panoramas. I have use the stacking element of the software to exposure stack my panoramas. especially for interiors Had I also taken sets at different focus points, it would have stacked and fused them at the same time. This is one of the Features of PTAssembler that few people seem to know about or use.

    This is a stitched panorama with exposure fusion with no additional lighting. As you can see, adding Focus fusion would have added little real benefit.
    The recti-perspective projection that I used, renders all radial lines as straight, hence the side walls are straight rather than curved.

    I use it very regularly for landscapes, to the extent that I have hacked a piece of software for my Android 'phone to give me the optimum focus points with the minimum number of frames, depending on aperture. I have stuck a calibrated and accurately marked focus scale on 24mm, 28mm and 50mm fixies.

    I also use focus stacking for macro, using a focus rack, but have yet to write software to optimize the step size, which is a bit more complicated as you need to know the magnification factor and the pupil ratio, which can change with focussing unless you have a pure planar lens.

    I use it when I need to & circumstances allow.
    When shooting through my microscope it's pretty much essential. In practically all cases I've not used enough images to maximize the effect - 5 shots across a fly's ankle proved completely insufficient, but focusing subtlety enough at high magnification is just beyond me:(

    Most of the shots I take have no need for focus stacking, or are in circumstances where it's not practical, like hand held macros of moving objects...
