[edit] Citations

Citations are mandated in certain cases according to http://en.wikipedia.org/wiki/WP:CITE#When_to_cite_sources . There are five cases listed there. Three of them—When you quote someone; When adding material to the biography of a living person; Material that is, or is likely to be, challenged—do not currently apply to this article.

Two others—Say where you got it, & When you verify content—are more debatable. The former addresses the need to cite sources properly, e.g., not to list a source in the citation when the source itself was acquired from an intermediate source. There's nothing here in that connection. The latter addresses the need to give citations when one verifies content, but does not mandate verification of any particular piece of information. If content is to be verified, it needs to be cited.

The last said might give rise to the question of whether any material here needs to be verified. I'm not opposed to it, but there seems to be a potential problem with doing it. It's not altogether clear what sort of citation scheme or model Wikipedia wants its editors to use. The project at http://en.wikipedia.org/wiki/Wikipedia:Forum_for_Encyclopedic_Standards broaches an issue: in many cases, information is more readily, or even exclusively, available in non-academic, non-peer-reviewed literature. It's often the case that the sources of information reside in trade journals or for-profit entities.

I think this is a good example of this. 35mm adapters were created as commercial products to serve a demand in the filmmaking industry, then branched out into the DIY guerrilla filmmaking world. Sources in the first domain are all commercial, in the second, mostly special-interest discussion forums. Since both are frowned upon by Wikipedia standards (though not necessarily prohibited), it's difficult therefore to provide citations. The same editor who put the "doesn't cite sources' banner on this page also removed all of the commercial & forum links.

Aside from that, other material such as the underlying principles (depth of field, 35mm, vignetting, barrel distortion, etc.) are properly sourced by referring to the Wikipedia pages dealing with those topics.

In light of this, I don't feel the banner was justified, & I have removed it. RubyQ 03:12, 4 December 2006 (UTC)

[edit] External Links is incomplete

I believe there is more to add to the external links / DOF Adapter list at the bottom of the article, like the Home Depot 35, or Go35. —The preceding unsigned comment was added by 24.23.51.27 (talk • contribs) 19 June 2006.

[edit] External links removed?

Too bad some people remove all those valuable external links. Instead of doing another add/remove fight, I'm instead copying the links here, so that it is not forgotten by people in the future:

[edit] Depth of field pictures in article

Hey guys, good to see the article I created so long ago has blossomed :) hopefully it's been of some use in clarifying the jungle of information surrounding 35mm adapters. Originally when I created the article I put the two pictures of depth of field at the top of the article, thinking that newbies to the world of depth of field adapters would need clarification of what DOF is in the first place. However upon reconsideration I have determined that the understanding of DOF is what brings people to this page in the first place, and if someone doesn't know what DOF is they can go to wikipedia's article entry to learn more about it there. Instead, I think pictures of DOF adapters such as the redrock unit, or the brevis, or letus, etc. attached to cameras or being used in the field would be more helpful in understanding these things. So, photo-savvy wikipedians, rig up your units and take pictures! I think this would be a valuable addition to the article. Funkbomb 23:43, 29 December 2006 (UTC)

[edit] History

I would remove the second paragraph completely from the history section. It is quite odd that there is less information on who originally developed the technology and more information on some people that have made the same thing at their home after the initial invention. When was it first developed and by who? Someone in Germany? I don't think that the second paragraph counts as history since at that point the technology had already been invented and used commercially.

Rather I would just say that since the principle is so simple, many people have developed and made DoF-adapters themselves. Now the second paragraph seems just original research.84.250.50.59 23:28, 28 August 2007 (UTC)
