Yes for FF (full frame) sensors. With a APS-C 1.6X crop sensor f/11 has the equivalent DOF of f/17.6 with a FF sensor. Cans use sites like the one HERE to check equivalent DOF and diffraction aperture for different types of sensors.

I think its good idea that you returned the lens prior to the end of the return period.

However agree with others that the amount of haze could of affected AF accuracy. I downloaded your above image and viewed in DPP 4 and shows you were using multi-AF points.

For the bulk of my shooting with optical viewfinder I prefer single center AF point.

Also played around with your image in PSE 14 with its new Haze Removal tool and did some sharpening -- sill soft when 100% pixel peeping but a slight improvement viewing at smaller size.

Cheers,
Jon
