The picture above is a 1:1 crop from the _central_ area of a photo taken with the A6000+SEL70200G (the shoot details are in the image). The lens is a very sharp one and all the branches in the photo, both at the left and the right of this section, are quite sharp (up to the borders of the photo). It's even not a DoF thing, since _all_ the branches in a larger tree at the left are sharp.

 

It's not a problem that ruins the photo, but I just don't understand which effect can cause blurriness in a limited, central section of a photo. 

 

PS It might be motion blur, in the sense that perhaps the branches were moving. But, apart the fact that I don't recall there was a wind strong enough to move naked branches, what's about all the other branches that are perfectly still?

 

Thanks.
