The Nikkor 180/2.8 ED, the AIS but especially the AF version, are sharper, have far less CA (the AF version is superior) and isn't that much more money.


Agreed on all points, assuming by CA you mean lateral CA.


Yes.

The AF version focuses VERY slowly and is in desperate need of an update by Nikon, assuming they believe that there is demand.


Nikon have released some updated fast primes recently (24/1.4, 35/1.4, 85/1.4, 200/2). In each case, the relevant zoom lens with which the prime would compete was slower (24-70/2.8, 70-200/2.Cool. It seems that Nikon believe zooms are for everyone, consumer to pro, and that the only marked for primes is pro-level, price-not-a-major-consideration fast glass.

I doubt, therefore, whether there will be an AF-S 180/2.8 despite the fact that it would have quite a different application to the expensive and heavy 200/2. And of course if they do make one, it won't have an aperture ring and won't work on extension tubes or bellows.


The questions is, how long can they still seriously peddle as "new", the 18 year-old 180 AFD? They can't be selling that many these days and if you're right (your reasoning is sound), they will likely discontinue it soon altogether.
