In the opening to this thread exitnine asked how does the 1.8 compare to the 1.4. While everyone has stated the 1.8 is a terrific lens and especially for $100, no one but Nute (it's not the 1.4 but hey, it's only $100 and pro IQ) has suggested that the 1.4 might be better. If this is true, in the long run, if the 1.4 is better, the $180 difference in price (assuming the normal Nikkor 50mm f/1.4D offered by B&H for $289.95 is the lens to which Nute was referring) might be worth it.
TRUTHDepends what you want.
If you want better, in absolute term, buy the 1.4
If you want the best bang for the buck, the 1.8 is unbeatable.
the 1.8 is sharper as the 1.4 - that was on eof the reasons, a bought the 1.8 after selling the 1.4.
