16-shot pixel shift shooting -- Unusable gimmic?

Re: Wrong example?

I see plenty of reviewers and example online showing that it does work as advertised.

There are two places to avoid using it:

a) when there is movement in the image, e.g. in landscape shots

b) when there is extreme shallow DOF, e.g. in your example

Additionally, your shutter time of 1.3 sec is quite lengthy, and prone to vibrations (softening).

For (extreme) macro, ie. very shallow DOF, I would suggest to use focus stacking, this is unrelated to pixel shift, but it gives you what I think that you are after.

For basic pixel shift at 4x versus 16x, 4x shifts by a whole pixel, and 16x shifts by half a pixel. For images which have clear sharpness defined at this level of pixel-detail, the image will up-sample quite nicely.

Try out some other scenes first, and then decide if your example is just a bad example. 
Particularly, start with an example which has a larger area of in-focus-plane details that show better when up-sampled (pixel-shifted).
