I am looking for some advise on edge softness with my 47 sa xl.
I have noticed that there is noticable edge softness in some of my pictures. It seems to be more noticable in the upper corners than the lower corners. For example the foreground looks fine but tree branches in the upper corners look fuzzy.
I am using an Ebony 45su and I am trying to keep the front and rear standards parallel and level. I think the majority of these shots were at f-22. Some with center filter some without.
Is there a sweet spot aperature setting I should be using? Is it a characteristic of this lens, or is it just my lens?
Thanks in advance for your advice.
