Today I decided to experiment with my Voigtländer 15mm lens and as a result I discovered a spot on my sensor and I have been unable to remove it … I can’t even physically see it. I have examined some of my earlier photographs and have discovered that the spot has been there for months.

To be honest I am finding it difficult to use this lens, especially wide-open, because it is a manual focus lens. Some photographs have a lot of distortion especially when the camera is angled. I should mention that I had gone to my local dealer to purchase a Zeiss Batis 18mm but after comparing both lenses I went with the Voigtländer 15mm instead and saved more than Euro 600.
