I bought this DA15 a year ago via eBay from SRS Microsystems in the UK.
I posted a few nice pics here and was happy. But now I am a little afraid of the results I see sometimes from the lens. I sent the lens two times to Pentax Germany and they quoted me both times "Lens adjusted".
Lets see:
f8; 1/1000
crop
f6.7; 1/350
Crop
I think the foreground is nearly perfect, but the out of focus areas in the corner are sometimes very blurry. For example crop 1. The ships in the middle who are mutch wider away are clear, the nearer ships in the corner are ..... .
Am I to critical in the view of the lens?
Please tell me your view.
Best,
Rainer
