Hi folks. I'm really enjoying using primes on the Fuji system and currently the widest i have is 23mm. I don't shoot wide that often but when i do... I really need it. I want wider than 18mm and can't afford the 16 f1.4. The Samyang 12mm F2 seems good value - but it's manual focus- not so bad on such a wide lens but still. Then there is the native 14mm f 2.8. Twice as much £ but it looks pretty good by all accounts... I shoot wide in landscape/forest/Urbex Any thoughts?
