Ive always wondered why nikon have never ventured anything faster than 1.2
I guess it is just R&D vs potential sales... not that there really is a need for one in terms of light gathering power now nikon have slrs capable of 102,400 iso
The thing that people often miss though, its not just the light gathering power, but the aesthetic that is attractive
People often criticise the nikon 1.2ais of being soft... If i want a sharp photo I wont use, a 1.2 lens!
I use it when i want something "arty" (i feel like i have said this so many times)
Larry refers to them as jewelry, and i take his point when they are hanging around the neck of a "gear head" but i bought mine for the effect it would have on the image
Basically un-processed, straight from camera
all kit should be used for its strengths ... try and use it for its weaknesses and you will dislike it!
Same goes for the nikon 50mm 1.4d ... shooting into the light reaps masses of flare ... but in the right circumstances, thats a aesthetic benefit, not the opposite ...
anyway, im ranting a bit here ... you get my point!
