What do you mean? I do not see any single piece back of the fruit focused.

In which case. Whatt's the benefit of fast focusing... If it is not focused?

In the G2 image the foreground leave is in focus whereas the fruit is not. Which makes it completely useless to compare with the G1 image in this particular sample. Likewise, the first two image comparisons give no valuable image data whatsoever from which to do a comparison. To which I'd add, do nothing to help the issue along I'm afraid. ie. what arguments such as these need are resolution charts and large sample averages so as to help reduce such things as copy variance and the likes.

There's more though I think this is plenty to put a proper perspective on the limitations of these particular samples imo.
