It also needs a better quality AF-S 50/1.2.

Actually I do not think a f/1.2 50mm is needed, the G50/1.4 is pretty good and 1.2 is what half a stop, just not enough to made a difference. What Nikon need is an AF-G 50/2.0 ( or 1.8 ) since theirs won't work on the like of D3000/D5000 Actually it would be better that they made it a 58mm/2.0 ( which correspond exactly as 85 on FX )

I think Nikon just needed to develop a AF-S 50/1.2 which is slightly better than the Canon 50/1.2L to win momentum. :wink:

IMHO, half stop is no big difference in quality say but it is a difference between being able to make it or not. Sort of like showing "quali" law....

I think 1.2 vs 1.4 is one-stop, not half-a-stop?
1.0, 1.2, 1.44, 2.0, 4.0 .... these are 1 stop difference?

Or was I wrong?

The f-stops comes with the approximation of sqrt(2xn) sequence.
f/1 = sqrt (1 )
f/1.4 = sqrt (2 )
f/2 = sqrt (4 )
f/2.8 = sqrt (8 )

and so on....

At this market niche, the f/1.2 is not going to be the factor when compared to f/1.4 ... and its not really showing off. What Nikon do with this 35/1.4 is both showing off and plugging the gap.

If at all, its the Tilt and Shift lens that Nikon need to address. Right now the 24/3.5 is no match for Canon's 24/3.5L-II TS-E not to mention the pretty amazing 17/4.0L TS-E ... Fast Lens is not all the rage these days , Quality lens is - ( even Zeiss refuse to get over heated with the lens speed as the ZA 24/2.0 shown ) - Nikon shown they can address the now hyped Wide angle need with both 1.4 fast fix focals and the 14-24 / 16-35.

Nikon Lens is almost always about quality at a conservative but usable manner, the recent ones are all that the 16-35/4.0VR and then the 24-120/4.0 VR ... I wouldn't be surprised the next to show in around something like a 80-200/4.0 VR, but for real I think the one lens they would made is a DX 17-55/2.8 VR-II
