[Brightcolours]

Not sure why you always have to bring equivalency into everything.

You're missing the point.

The point is that my Fuji 18mm's corners are not that bad compared to the samples shown here.

Nothing more, nothing else.

You don't take into account correcting the CA. With your not very wide angle lens, I am sure you do have CA correction. And you compare corners from 11mm (which always will look pulled apart in some way or another) to a mere 28mm equivalent. Which is the odd thing.

 

Also... To what are you comparing 45.7 megapixel images, exactly?
