True that.
I'd still take the 1.4 over the 1.8 though. The 1.4 is still very affordable, faster, better built, has nicer bokeh (see the comparison of bokeh in the review that Brian did over in the reviews section) and is a very fast and good performer in low light situations. Image quality is also noticably better than the 1.8.
