I have this odd relationship with the 23 1.4... I love the images from it (up close / portrait at 1.4, "everything in focus" at 2.8 or above, don't love wide shots at 1.4). But I often don't love using it as much as other lenses. It's big, heavy, my aperture ring sticks, the lens hood is a petal style, and that do-it-all focal length means that while it
A) Does fairly well at everything, it
B) Doesn't give you any focal-length-advantages. What do I mean by that?
By that I mean that with ultra-wides, you can stretch out the corners and let them run, clawing in all the periphery into the compostition, making the picture look "different," which is paramount in the age of "everyone has a camera in their pocket but they're all one wide focal length." And with longer focal lengths you have that compression, the shallow depth of field, and the lovely isolation of not having half the free world in your composition. The 23 "does it all," and there's no debating that. But for a prime, especially a prime **on an interchangeable lends body**, it doesn't give you any "focal length tricky" that I so often love.
I had the good fortune of being taken for lunch today at work, including two beers, so take this with a grain of barley.
