Now, the question is, is it really going to make a difference for you? It may not. I used to swear by my 50 mm/1.4 and now it doesn't like my D2X. Nikon themselves say that the D2X is too advanced for the 50 mm/1.4, go figure! lol! The 1.4 worked great on my D70 though.
If you are a hobbiest, go for the 1.8, and put the rest of your money toward another lens
well the 2 lenses are the ones that are in my budget at the moment
so im thinking ether i spend all my money and get a good lens being the 1.4
or do i save that little bit of money and get the 1.8 ...
I want to get the best results i can .. and there is no one i know that has ether of the lenses so i could try them out and see for my self .. so I'm relying on what people tell me ..
In theory, the F1.4 is a tiny bit better - it's one more stop for letting in light faster and may be a touch sharper, but not much. The 50mm f/1.8 is one of the best bargains in the entire lineup - it's sharper than basically any other sub-$1300 lens.
I could find any direct comparisons except for hearsay. Seems like a common opinion is that the 1.8 might be a little sharper, but that the 1.4 has better bokeh.
I would (and did) get the 1.8, unless you're shooting in conditions where you really need every single last bit of speed, the difference is only half a stop and so you'll probably never notice it.
And for the difference in price I dont think there's enough difference in lens.
if money isnt that important and you can easily save up again..... i would go with the 1.4..... but if like me, you dont have alot to keep spending on your camera equipment, get the 1.8......
Personally i think unless your a professional or VERY fussy about your images, you wont notice the difference...... but like Markc says..... the 1.4 has better bokeh...... thats about it.
