I recently bought used 16-35 f/4 lens for my D600. I took it to shoot traffic trails, results are disappointing. Edges look soft to me even stopped down to f/16. May be I had high expectations on this lens reading all positive reviews. Please tell me if below samples look soft to you.
Both are original size and JPG SOOC. Forgive me for the huge files and sensor dust on my D600.
D600 - f/22 - 30sec - ISO 100 - Tripod (VR off) - Focused on top of the tallest building. Edges of the buildings (Even the one I focused) and freeway look soft to me.
D600 - f/6.3 - 1/125 - ISO 800 - Handheld - Focused on top of the building. This isn't too bad as the other sample.
