After looking at lens reviews, can someone enlighten me why would 1 choose to pay a premium for a f1.4 to a f1.8? Does it gives better night photography choices? eg. faster shutter. Or simply the bokeh can blow one's sane mind?
The premim paid on lenses, is realy for the glass, better quality glass, advance coating, gives better resolution, color, contrast ... just to name a few of the attribute each and every one of us are looking for.
