Why no ULTRA wide primes??

As usual, Mr. Rockwell's review is full with approximations and inaccuracies. In fact, this 13mm Nikkor is far from being Nikon's greatest lens. It has indeed a very low distortion on the edges of the frame, but it does distort in the center. It also exhibits plenty of chromatic aberrations and is not particularly sharp compared to modern superwides...


There are bigger, rarer, more expensive, more unique and "greater" Nikon lenses. For example, the Nikkor 6/2.8 (5.2kg on the scale, 220° FOV), or the 1200-1700/5.6-8 (only 15 ever made,16kg and a length of over 800mm)...

Here's the 13/5.6 with a D300:

And the 1200-1700/5.6-8 with a D3:

And what about the Sigma 12-24/4.5-5.6 and the Voigtländer 12/5.6 -- this lens was initially designed for rangefinder cameras, but there is also a version in Nikon mount for Nikon SLRs? Not pro enough?


I don't really get the point: 51.6mm instead of 50mm is a 3.2% increase, while 13.3mm instead of 13mm is a 2.3% increase, not much of a difference!


No thanks! ;)

Cheers!
