I just ordered the 23/2 today, expected delivery is on friday
There are many reasons why I choosed it over the 23/1.4
First of all it was the size, the 1.4 is too big for my taste - expecially as a "always on" lens.
Price/value also matters - I don't think that the 1.4 gives so much better results in comparison - and in combination with the size/weight it is just not worth to me.
AF Speed: I heard that the new 23/2 is blazing fast in af, and since the 23 will probably be my "always on" lens, I appreciate the speed for my playing daughter.
I had a X100s a few years ago, so I know that f2 will give me enough room for low light and subject separation. And I also have a 35/1.4 for certain situations where the aperture is needed.
And last but not least - 23mm is not always 23mm! According to different previews, the new 23/2 seems to be a little bit wider than 23mm.
This is something I really appreciate, because it gives a little more room in certain situations and the step to my 35mm is not so close.
