I'm looking for a small sized, portable lens with 23mm or 35mm (if it's a 35mm lens, it needs to be compatible with a Metabone or Zhongyi adapter to get 'real' [full frame wise] 35mm). The Fujinon seems too bulky to me, despite the excellent quality! The Voigtländer lenses are very interesting, but there is no compatibility (Leica M) with the current Metabone/Zhongyi lineup. Although, the Voigtländer focal lengths are a bit odd for my wish list
