Summary: I'm a professional photographer, I do commercial work and fine art, so I have used many types of cameras. I was hoping this would be a good alternative to a tilt shift lens. The problem I found is that it really only does tunnel focus. I'm not saying it's useless, but it only does one specific thing and I don't think it's worth the money for something I can do very easily in photoshop. It doesn't come close to a tilt/shift lens.
Summary: Diese Linse ist ein witziges Baby. Mir sind die Abstriche gegenüber einem vollen Till/Shift-Objektiv gegenüber aber zu gravierend. Sicher kann mensch diese beiden auch nicht vergleichen... Deshalb zurück zum Superservice von Amazon.
