I'm surprised at the Depth of Field in the sample shots.
At F1.4, I would expect there to be *zero* DOF... but the DOF was surprisingly...deep.
Is that a function of the lens? the full frame camera? distance to subject? Or is it my lack of understanding how DOF works? :\
The further the subject from the camera, the greater the DOF will become - but it's all relative when compared to other apertures.
Is there something that says all sample images were shot at 1.4?
I Was referring to the images in the review video. Most of them are labeled.
The landscape image at f/1.4 was shot at a distance of 75-80 feet away. The depth of field of an 85mm lens at f/1.4 at that distance is slightly more than 20 feet. If you reduce that distance to the subject to 7 feet the depth of field becomes only 2 inches. With most lenses this doesn't really matter - shooting infinity subjects at wide apertures is a joke, but the microcontrast, resolution, and lack of CA on the Otus line makes shooting wide open infinity subjects a reality. That was part of what made the lens so unique.
Here's an image I haven't shared before. Wide Open, medium distance (about 50 feet). Dead branches against a blown out sky. This is wide open (f/1.4). Check out #1) the great detail in the tree (and contrast in this high contrast setting and B) the utter lack of chromatic aberrations/fringing in a scene that would be full of them with many lenses. I have not applied any profile to correct anything. It is a conversion from RAW only (I did remove a distracting power line from the sky)
