PLEASE could somebody from Sony or who can get in touch with anyone there find out if they plan to include this feature at any point. They will soon be the ONLY company that doesn't offer the feature and I simply don't understand it? (It must surely be the most requested feature I've seen...)

If it's a yes, a timeline would be appreciated so people don't go blowing money on 3rd party equipment to do focus stacking.

If no, an explanation as to why not would be much appreciated (is there a technical reason that it can't be done?)
