Since I have the 14 2.8 which I love, and had the 35 1.4, a really terrific lens, when the 35 f2 came out, I sold the 35 1.4 and got the 35 f2. To me the IQ of both 35's were very similar but the big difference was the focus speed and almost silent 35 f2. It is also a little more compact than the 1.4. Would I like to shoot with the 23? Probably, but for now, the 14 and 35 are great, small, high quality lenses. I have one on my X-E1 and the other on my XP1.
