i was using both 1.8 and 1.4 on nikon
but actually preferred the 1.8 sharpness in the wide aperture
dont know about canon tho
My 1.8 is sharp wide open, but some copies aren't. Canon's 1.4 is a better lens of course, but you can't beat the value of the 1.8.
Some things you may not like about the 1.8 are build quality, AF noise/speed, AF/MF switch, MF ring. Personally I really like my 1.8, but if you don't mind spending extra get the 1.4. I may get a 1.4 down the road a bit but the 1.8 fits my needs right now.
