[QUOTE="AperturePriority, post: 52769, member: 9275"] I am not wrong here, westwing! I easily agree with you in general, sweet spot of a lens is about 1-2 fstops closed down. That happens because of technical limitations of the those lens designs. For good designed (nocturnal, for example) lenses, the more you open the lens, the sharper you get in your images. And for the 300mm AF-S with wide open f/4 the sharpness you can see from edge to edge. The best sharpness of a 58mm 1.2 Noct is at f/1.2, not at f/4, 5.6, or 8... [/QUOTE]
