In order to get everything sharply focused in the "you-are-there" near-far sense that I enjoy, I have persisted with trying to find a reliable way to use this focus-by-wire lens in combination with Sony's integer readout, and think I may have found something that helps.
It turns out that with this lens at least, but I suspect others also, that although the integer readout is very inaccurate, the distance at which the integer increments is highly repeatable according to the exif.
I did three repeats of finding the change-over point between 1m and 2m, both at 14mm and 24mm focal lengths, and the exif was very close to 1.4m in all cases. Similarly, the change-over point between 2m and 3m was always very close to 2.5m.In other words, I can know the lens is focused at 1.4m if I carefully find the point at which the display just toggles between 1m and 2m. Similarly I know I am at 2.5m when the display just changes between 2 and 3m.
You can find other toggle points according to your typical interests, but for me these two distances in particular will be very helpful in typical landscape scenes. Perhaps I should also post this as a separate topic for readers not interested in this particular lens.
** edit *** the toggle point between 0.9 and 1m consistently is at 0.9m according to the exif. So now I have three well reliable focus distances at 0.9m, 1.4m, and 2.5m that correspond to the readout change-over points between 0.9m-1m, 1m-2m, and 2m-3m respectively. I will look forward to using these in the field.
