Kurt Munger's test is very detailed, it concerns both full frame and APS-C and every aspect of optics that one could imagine.
The Sony Carl Zeiss 24mm F/2 lens is expensive, but is it worth the price? As I explained above, it has some really good qualities, and a few flaws for a very expensive lens, it all depends on what's important to you. Based on some preliminary tests, I'd say if you own the CZ 16-35mm and/or CZ 24-70mm, and won't need F/2, then you probably won't benefit from the CZ 24mm. However, F/2 is a whole stop faster than F/2.8, that's a big part of the additional expense, and very important when doing hand-held shooting in low light. Also, if you're a person that likes 24mm, and aren't interested, or not in need of a zoom, then by all means, go ahead and try it out, it's a lot lighter and smaller than the CZ zooms mentioned.
Kurt Munger's review method is close to real life test, even if you have already read the Photozone and dpreview reviews, it is still worthwhile to look at Kurt Munger's review.
