Official: Voigtlander 15mm f/4.5 III E-mount
Well that was a worthwhile exercise. I'm actually very surprised at how good the FE 16-35 held its own compared to the CV 15 III and even the Loxia 2.8/21. The Loxia 2.8/21 still out shines both of these other lenses but given the 16mm focal length I'm thinking I have a decent version of the FE16-35 f/4. I have the Batis 18mm on order so I'll be interested in doing a similar comparison when that arrives. It is really hard to understand the sample variations that exits. Fred certainly had a couple of bad samples that he tested. I really hope that Sony comes out with a 14mm - 24mm f/2.8 GM or a 16mm - 35mm f/2.8 GM with similar IQ to the excellent 24-70 f/2.8 GM lens. If the Batis 18mm tests almost as good or better than the Loxia 21 we will have at least a fairly wide angle lens to work with in the mean time.
