you say that cause you have not tried it
once you do you will change your mind
my advice dont try it
you can get damn fine images with the kit lens if you work around the limitations, I personally hate the 50 1.8 it misfocused far to many times for my liking, the 50 1.4 on the other hand I really like.... but when the 50 1.8 focuses its definetly capable of very good images, its really near as good image quality wise as the 1.4
