[Brightcolours]

Strong "cat eye" on the upper right.

 



 

 

The Sony/Minolta 135 STF had perfectly round blur on the entire frame (and zero vignetting).

See some comparison vs many 135:

The narrow mounts it has to support of course makes for some cats eye. You can't avoid that, nor is it something bad. The 135mm, being 135mm, has a bit easier job there, and having to allow less mounts.

So what is your point then? That it is not an exact copy of the Minolta 135mm f2.8 STF? Yes, that is correct. And I am sure it will be less expensive too.
