I think we should be fair - the dead center IS sharp. THis is also supported by the MTFs.

However, the drop in performance is rather drastic from here on.

I cannot know whether I got a good or bad sample - the resolution seems symmetrical though.

 

I got the 'lens' for 49$ in the US so it's hard to complain somehow. That said there is not a hell of a difference in size compared to the pancakes (Oly 17/2.8, Pana 14/2.5 or 20/1.7).

    

Well, I think you've summed it up fairly, Klaus,no great lens but for the price of a couple of rounds of beers (with the whiskey chasers)  can't grumble!
