Okay I think I have a problem with my lens. HD2000 here.
Recently, I got a step-up converter + 52mm variable ND filter + 55mm lens hood.
Now here's the deal: With the lens hood attached, I am seeing severe vignetting on the left part of the screen
. On the camera's LCD, I can actually see the inner part of lens hood in the upper and lower left corner.
The right corners feature a clear view with minor vignetting.
This appears in photo view mode, e.g. when the LCD shows what a still picture would look like (instead of video). This is the mode that uses the entire sensor.
The converter ring and ND filter seem to be installed correctly.
For reference, here is a photo I took:
And this is the lens hood:
The vignetting was to be expected. I am, however, shocked that it is not symmetric. In fact, the left part of the image shows much more of the lens hood. Could it be that some part of the lens got tilted towards the left?
Maybe someone can check their photos to see if they have the same problem. Maybe this is by design.
I did notice that especially at wide aperture / low f number I was getting terrible results when the focus was set beyond macro distance. The picture was blurred. To get sharp pictures with acceptable results, I had to use narrow apertures pretty much all the time. Even on tripods. Obviously, a wide aperture has a shallow DOF but if the focus is set to an object that is 3 meters away that object should be sharp. I did drop the camera before noticing any problems...
