A quick comparison of two raw, limited-post-processed images that I made this afternoon. These were both taken with my Sony a7R, the Voigt with an inexpensive adapter, and the Zeiss-Sonnar as a native E-mount. The were both taken at f/2.0. The Voigt was manually focused using the peaking function, and the Zeiss-Sonnar employed its auto-focus capability. Voigtlander 58mm f/1.4 Zeiss-Sonnar 55mm f/1.8 Feel free to offer comment. I feel that the Voigtlander is the superior lens, especially considering that it was manually focused. --- edit --- I just tried to delete this post because I found a flaw, but I don't seem to see a way of deleting it. The flaw is a significant difference in exposure details. It essentially invalidates the comparison. So I am going to redo the comparison and will post a better set of comparison images from these two lenses.
