Alin Popescu tested both new wide angle lenses and posted many image samples and comparisons on his website:
The lens is straightforward to use, with excellent handling and smooth zoom and focus ring movement. They’ve said the drive by wire was improved and I must agree.
The lens is an amazing performer starting wide open. And very resistant to flare and resolves all scenes with minimum Chromatic Aberration.
Serious resistance to flare and minimum aberrations with superb contrast. I have found it even better compared to the G Master when it come to Chromatic Aberration handling.
Sharpness wise, this lens is a performer. It’s very sharp corner to corner, ignoring the normal distortions for a 12mm.
