I'm using S3 Pro and intends to get a prime len but can't decide whether to get AF-S DX NIKKOR 35mm f/1.8G or AF 50mm f/1.8G. Mainly i'll be using it for portrait shot and occasional landscape. Mostly for landscape i'll be using AF 14mm f/2.8. Need advice from experienced photographer on what should be considered when buying prime lens and how to decide which focal length to get. TIA.
