I have both 25/2.8 ZF and 25/2.8 C/Y.IQ wise they are very similar i.e. very good on FF and APS-C.ZF is best at infinity and close ups,but does very well in medium distances stopped down to f8.C/Y does not have close up facility but renders images of comparable quality.ZF looks slightly crisper and is a tad sharper in corners,but there is enough 3D look in 25/2.8 C/Y when used rightly.If I had to chose I would get the ZF first.
