I notice some weird softness issue on my new 16-35L II. Sometimes it is there, sometimes it isn't. Some kind of glow against high contrast areas. But it doesn't look like fringing. It happens mostly in the 20-28mm range.
See this example at 24mm, f/2.8, 1/1000th
Here the whole snapshot:
Here is a 100% crop of the area in focus:
Zoomed in to 200% to make it more visible (top side of cup and white chair):
While I really have to zoom in to see the phenomenon clearly, the whole picture itself lacks contrast and clarity, making it soft looking. Shall I return the lens to the seller? Sure would help if I have some idea of what is causing this. It doesn't seem to be focus related.
What do you make of it?
