These two are like night and day, foresight and hindsight. Hindsight looks to the past and shoots 20/20; foresight not so much. The Lytro is my daughter's camera and we'll be putting mileage on it soon.
On to the subject of the 21mm Biogon ZM. Here's a pair of samples for the Biogon, and this time the links point to full-res files ( warning: 20MB jpegs) because they're intended for maximum pixel-peeping:
They're really very good. They're also shot at f/8. My first surprise was that the lens isn't anything special when shot at f/2.8, or even f/4 sometimes, the Distagon does better.
My second surprise is that, due to an accident of the shipper, I got to see a silver version of this lens in addition to the black one I have above. The aperture ring on the silver lens was terrible - it was stiff and I could barely feel the detents. I was really afraid my black copy would be the same, but thankfully it feels like a real Zeiss ZM.
More to come later.
