Thanks for trying to create a comparison article, however it seems incomplete given that the old Panasonic Lumix G 20mm F1.7 ASPH was never tested by you. Also the more recent Panasonic Lumix G 14mm F2.5 ASPH has not been tested by you.
These lenses have been widely available for quite some time...
Indeed it has been so long since that 20mm was released, there is actually a new version soon - the Panasonic Lumix G 20mm F1.7 II ASPH (which you should test) but people will still be curious as to how it compares to the MkI version (which you have not tested).
I hope you can catch-up on your Panasonic Lens testing backlog for the sake of data completeness.
