I did try it about 20 years ago. Personally, can't call this optical formula successful. There is one major plus - almost full absence of geometrical distortions. But, in opposite to removed distortions, as usual, the lens is mushy, especially to the corners, even center was so-so. One more negative side - flares easily, from any source of light. Last 14mm Nikkor is way better of every respect, some distortions correcting fast in PP, without any significant sacrificing of field. 15/3.5 is between them. 14-24 zoom is sharper, too, but flares. The best very affordable wide lens today is, in my understanding, the last Tamron 15-30. The Sigma 12-24/4 is very good, wider then anything else, but heavy and without IS. My own choice you already know, Tokina 17mm, sharp and contrast one, with efficient flare suppression, cheap, but is not that wide. Please note, it is my own personal opinion, nothing more! THX! LZ
