I still don't understand what you don't like about your 50L.. you failed to specifically tells us what you don't like about it. Are you talking about AF accuracy???
I think it's the focal length that doesn't work for him...
I myself used a 50 1.4 when I first started out. I used it for everything and I really liked it, however I found myself standing way back whenever I was shooting indoors such as houses, or parties. I bought the 35L and sold the 50, and don't regret it one bit. I feel like the 35 does everything my 50 did and more. I just have to get a little closer for portrait type stuff, which I do a lot of with kids. I found kids tend to look into the camera better when it's closer. As for the IQ between the 35L and 50 1.4, as assumed the 35L is better. As for the IQ between the 35L and 50L, I can't speak to. I have a really good friend who has the 50 1.2 glued to his camera, so it's truley different strokes for different folks. I myself believe that finding the right focal length/s that work for you should be the first step, then find that right lens that has the features you need ie. zoom/speed....Just my 2 cents....
