Images

What happened to all the images in this article? Ehn 19:35, 12 November 2006 (UTC)

Long story -- I used other people's images to create the montages, and I dutifully got permission to use the images, but I didn't get explicit confirmation that the owners actually owned the images. The light-meter has cleared, and the Nikonos II will probably clear. The light meter is rare, and in this case well photographed, so that was the more important of the two.--John Bessa (talk) 15:07, 30 July 2010 (UTC)

Mounting

Could the Nikonos mount standard Nikon lenses of the period, for use above water? -Ashley Pomeroy 18:12, 26 February 2007 (UTC)

I believe the answer is yes, but I can't recall the citation.

Impossible w/o an adapter; two totally different types of lenses. You might want to look at material I removed: Digital Nikonos Industry Design Challenge. I removed it because it never came to fruition, though it looked like a nice attempt! (Also a little off-topic.)--John Bessa (talk) 00:48, 26 June 2010 (UTC)

Extension tubes

Does anyone know of an online resource which describes focus and aperture settings recommended with the Nikonos (I through V) extension tubes? Would a sentence and citation about this improve the utility of this article? Also, relative to the framer, which part of the subject will be in sharpest focus...its proximal (defined) end, its distal (defined) end, or into the subject, at a depth about equal to the framer's width? Does aperture profoundly affect this? I can imagine it may be hard to answer these questions within the guidelines. Newportm (talk) 04:09, 17 July 2009 (UTC)

Actually I think that it would violate the "how-to" rule; this is an encyclopedia and not a how-to site. This isn't a show-stopper however because you can create a similar page on the |Wikiversity and direct people there. Wikiversity is conceived of as a school version of the WP.--John Bessa (talk) 15:50, 30 July 2010 (UTC)

Underwater Lenses: Difference between amphibious and UW

It would be really interesting to understand and relate why UW is better than amphibious underwater. Increased diffraction of light plays a role and that the lenses are "anigstigmat" in relation to this, but I have no other knowledge. One of the sources says "saturation," and early underwater photos lacked exactly that, so I wonder if the glass content and coating are working her in some complex way.[1]--John Bessa (talk) 15:44, 30 July 2010 (UTC)

Material on the I, II & III

[2]

Note: it may make sense to put of the Calypso innovations that defined the Nikonos here, and even merge the pages

Calypso (1961/1962)

• The shutter is cocked when the advance lever is pushed back to the "ready position"
• Original lens for the Calypso was a 35mm f3.5 Som-Berthiot with a "filter" protecting it from water.
• Sealskin trim
• Mfg by the French bottled gas company that absorbed Cousteau's aqua lung invention to ultimately become Aqua Lung America, and possibly US Divers

Nikonos I (1963)

• 35mm f2.5
• Plastic coating

Nikonos II (1968)

• Rewind crank replaced knob
• Flash capability
• Improved distance and depth of field frames on lenses

Nikonos III (1975)

• Enlarged controls
• Bright frames for 35mm and 80mm
• Parallax marks for distances below 80cm
• Film exposure counter on top
• Three-pin flash terminal
• Lever can be used with short strokes
• Internal improvements
• Lens mount no longer part of chassis

Ektacolor

There were Ektacolor Type S and Type L, the C-22 predecessors to Vericolor Type S and Type L. There is no article page for either Ektacolor or Vericolor, but there should be (at least) one. If one meant Ektacolor-S instead of Ektacolor-X, change the link as appropriate. Ektacolora and Vericolor are negative films similar to Kodacolor. Gah4 (talk) 23:31, 12 November 2018 (UTC)
