I am looking for a good, clean, and razor sharp lens with an angle of view greater than 90(degrees) for some landscape work. It is very important that the distortions be minimal since there are a lot of angles and lines in the scene that will quickly reveal imperfections.
Jason, Some wide angles are free of distortion, others are razor sharp. Since you insist on both, you help narrow the field: 20/4 Carl Zeiss Jena (77mm filter). Not as sharp as the later 20/2.8 (which shares the basic optical formula with the Pentax 20/2.8), but the 20/4 is probably more rectilinear than any othe 20. All but the last batch were single coated. And I'm araid none were K mount, just some M42s (and Practica bayonet). SMC Pentax 24/3.5K. As good as it gets in sharpness and rectilinearity, with SMC coating, too. SMC Pentax 24/2 FA. Perhaps not quite as distortion-free as the 24/3.5K, but it just may be sharper. And it's certainly faster! Even die-hard fans of manual focus succumb to its awesome optical quality. Finally, check out the new Sigma 20/1.8 and 24/1.8; I believe each takes a 77mm filter. They've been gaving great reviews, though don't expect the build quality and coating to be up to Pentax standards.
