The Viltrox AF 13mm f/1.4 XF is now marked as in stock at AmazonUS (via Viltrox) and is also available for pre-order at AmazonUS, AmazonDE and AmazonUK via Pergear. You can also get it directly at PergearUS and PergearDE.
Some FR-readers wrote me that they have already received their lens. Looking forward to their images and to hear their experience with this lens. It’s definitely a nice addition to the X mount lens lineup.
