Sort of Macro but a little different: This was taken with a lens I bought in Canon mount and have posted results from before but not usually thought of as a macro lens. There are clues to the ID of the lens in the image (taken at f/8). I'll point out that this was taken with the lens not properly attached to the camera.
No extension tubes were used. Care to guess what is going on here?
Answer below:
The Zenitar 16mm fisheye was handheld in place but not attached to the camera. It was tilted forward slightly to cause the Depth of field to angle slightly almost (not perfectly) matching the desired plane of focus. The lens focuses normally to .3 meters but this was taken at about half that. This is a very low end tilt 16mm macro. Stopping down to f/16 might have done the depth of field but nobody makes an extension tube less than 12mm and that tube with this lens focuses at about a centimeter which is way too close for practical use.
