Agreed, pdh. ~tc~, initially I removed your provocative remark to OzRay, but then thought better about it and apologize for it appearing that I changed anything. I see that you and OzRay have both been going back and forth for a while in this thread, so I don't mean to single you alone out, tc. We all need to leave personal remarks out of the discussions on this forum. It's fine to disagree and even prove our points to make it clear that someone else's remarks may not be accurate but we do not need or want personal attacks.this doesn't seem to me like a comment that helps the discussion along ...
And for the 17mm:Falloff
We consider falloff to start becoming a potential problem when the corner illumination falls to more than 1 stop below the center. We measure 1.7 stops falloff wide open, which disappears on stopping down to around F2.8 - this is unlikely to be noticeable in normal use.
So, it would appear that you have to go to f2.8, before the 20mm loses that fair loss, though the way they use the words little etc, the measurments don't appear very empirical. :smile:Falloff We consider falloff to become perceptible when the corner illumination falls to more than 1 stop less than the centre. There's just a little falloff wide open (1 stop), that disappears by F4 - nothing to worry about.
Horses for courses. 1 1/3 stops vs. 3mm.That said, I still maintain that to have made the 17mm even an f2 lens, would have made it bigger and more expensive, it's simply the math of lens design, especially with wide angle lenses. Also, I have a lens that's 3mm wider and, to me, much more versatile than a 20mm.
The Noct-Nikkor never sold for $800 AFIK unless possibly around the time of its introduction in 1977, but I doubt it. When it was last on sale in the US, it was around $2200 and that was in 1997. There were about 11,500 of these made in 21 years. It was always a very expensive lens as it was hand ground.He, like Moose Peterson, seems to favor fast lenses. His Nikkor Normal is the 58/1.2 Noct-Nikkor. These used to go for $800, now seem to be in the $3,000 range. The lens is designed to give peak contrast performance at 10LP/mm. Ten-Line-Pairs Per Millimeter. It was announced in Photokina '76. But it is the most expensive Nikkor Normal you can buy, and can be found in Thom's Bag. I've used a 55/1.2 Nikkor-SC on my F2SB for a long time. Over the center 2/3rds of the image, it beat out the 50/1.4 Nikkor. Cost $125. Is the Noct-Nikkor 20x better?
Well, Ken Rockwell writes himself:I can't be the only one that finds Thom Hogan nearly as tiresome as Ken Rockwell ... can I ?

I've been shopping KEH for over 20 years. I've seen it that low. I know the lens, I worked in a camera shop during college. I have the Nikon Dealer's Catalog with the lens listed in it. The 50/1.2 Noctilux was aspheric, interesting about it's performance. The 50/1.0 dropped the "wiggle". The Canon 55/1.2 SSC Aspherical is comparable to the Nikkor and Leica lens. Cost- under $800 these days. If Canon had kept the FD mount, I guess it would be closer to $3,000.The Noct-Nikkor never sold for $800 AFIK unless possibly around the time of its introduction in 1977, but I doubt it.
The $500 lens you are thinking of is the 55mm f/1.2 which is still in production but not in the same league performance wise (it is still a very good lens).
It's available for $650.00 if you search.
That's a great price.
That's what I thought and why I jumped on a very lightly used one for $600That's a good price for it and getting to about what it should be. It certainly ins't available in Australia for that sort of price.
