I'm a relative novice landscape shooter and don't own any primes. I keep wondering what noticable image quality advantage primes may offer landscape shooters in good light at base ISO? I shoot with an E-PL1 with its 14-42mm kit lens. See example below shot at 14mm. Would I really notice any more detail in that already sharp and detailed image if I used a Pany 14mm 2.5 prime on the E-PL1?
