See my Sony mirrorless wish list at B&H Photo.
This near-to-far landscape from f/2 through f/13 shows off the full behavior with stopping down: foreground and background bokeh, total image quality at each aperture when in focus and not in focus, etc.
Examples at sizes up to 28 megapixels from f/2 through f/13, with large crops also.
The about $1299 Zeiss Loxia 35mm f/2 Biogon is a winner for landscape shooting. An unheralded attribute is its zero distortion (< 0.2%), always rendering the scene more naturally than any other 35mm lens.
