I must confess I am not that interested in expanding my lenses with auto-focus versions. Auto-focus is beneficial for zooms but less so for primes from my standpoint. I am just as happy with manual focusing in most cases. I have several adapted lenses I love but I would like smaller native versions. And as a casual photographer I further confess I want inexpensive (read: cheap) lenses with good but not necessarily professional build quality (e.g. Nikon E series). Voightlander lenses are too large and too expensive for me. The Samyang 7.5 strikes the perfect balance and would love to see them make even more. Native manual focus prime lenses I would like to see? 1. 10/2.8 2. 25/1.8 3. 50/1.8 (replace my Pentax 50/1.4) 4. 85/2 or 100/2 (replace my Minolta 85/2) 5. 100/2.8 Macro (replace my Micro-Nikkor) 6. 200/2.8 (replace my Pentax 200/4) I have the 14/2.5 and 20/1.7 Pannys and like them fine as they are but if/when I replace then I would probably get fast wide primes in the same or similar lengths.
