Talk:Telephoto lens

message: I have placed a request on zoom lens to merge into this article.  There is duplication between this article and zoom lens.  I think the two articles should be combined.  I think a zoom lens should be a subcategory of telephoto lens, as the distinction is basically a zoom lens has a varying focal length.  The issues as to what a focal length is, what an angle of view is, and how these things are related are common to both.  Furthermore, the artistic aspects of using a telephoto and zoom to me seem to be the same.  Bottom line, there is information in the zoom article that relates to telephoto and vice versa.  --Lenehey 22:32, August 22, 2005 (UTC)
NO ! It's a common confusion. A telephoto is not a zoom. And the artistic aspects of using a telephoto and zoom aren't the same especialy if we extend the topic to the use of zoom in movies and video. There's a (very incomplete BTW) article about photographic lenses another, another about wide-angle lenses, another about normal lenses, another about zoom lenses and I think it should stay like this.

thread_title:  Telephoto / Zoom 

message: There seems to be a little bit of confusion in this article. It starts by saying that a telephoto lens is any lens with a focal length significantly longer than the focal length of a normal lens but then saying that a telephoto lens must include a telephoto group.
I think the article needs clarifying. Specifically, I think these points need to be made:
1. A lens with a focal length significantly longer than the focal length of a normal lens is a long lens.
2. A telephoto lens is an optical design that has the property of allowing the lens to be physically shorter than the focal length would suggest. A telephoto lens need not be a long lens but generally is.
3. The term telephoto is commonly misused to describe any long lens.

thread_title:  Correction 

message: This article could use a sentence or two before where it currently starts or a bit of rewording. It would be more helpful to include a short (if somewhat imprecise) definition of what a telephoto lens is. To someone just coming in, the first paragraph's focus on what isn't telephoto will probably not be entirely helpful.

:AMEN BROTHER!  All I wanted to know was what it did, not how it did it in excruciating technical detail.  One simple sentence, then you can get to the technobabble. Scottanon (talk) 21:50, 1 April 2009 (UTC)
replies: text: I agree, the lede lacks a basic defintion.  Just one sentence that states, "Telephoto lenses are typically used for..." or "Photographers prefer telephoto lenses when..." would be very helpful.  Bms4880 (talk) 22:20, 9 March 2011 (UTC)
thread_title:  Clear definition 

message: Why do some of the thumbnail images appear to be out-of-focus?  Does that happen during the reduction?  I don't know too much about digital manipulation. 66.57.225.77 04:00, 29 October 2006 (UTC)

message: The opening paragraph of this article specifficaly excludes "Long Lenses". Why does Long lens redirect here? If something is not included in a definition should not be redirected and maybe even have its own article?69.72.7.39 16:23, 9 January 2007 (UTC)
replies: text: The term "long lens" is almost always used to mean "long-focal-length lens".  Most long lenses are telephoto lenses.  Furthermore, while the formal definition of telephoto excludes lenses that aren't shortened by a telephoto optical design, the informal use covers ALL long lenses.

message: This is one of the most uninformed articles written on Wikipedia, through and through. Factual inconsistencies, falsehoods and random made-up BS. This article doesn't even deserve to be panned for its grammatical butchering because the content is so awful.  Evil Prince 01:14, 15 October 2007 (UTC)
thread_title:  Without a Doubt... 

message: The photo shows a Beroflex 500/8 lens and the captions state it is not a telephoto lens. I own this lens and it is definitely constructed as a telephoto lens according to the description in the article. It is also less than 500mm long. It is rather long compared to modern lenses, but still a telephoto construction.  —Preceding unsigned comment added by 89.56.141.46 (talk) 22:09, 14 June 2008 (UTC)

thread_title:  Picture caption not correct? 

message: Cleaned up article for style, WP:MOSBEGIN,  WP:JARGON, and general referencing. Some images did not seem to fit WP:IMAGE per: not being informative, or even readable at thumbnail. Also moved some material off to Long focus lens since reference, article content, and most editors on this page point to the telephoto being a specific construction/sub-type of a long focus lens. The prose style is still a little teach-ie. The added paragraphs on Alexander McKay look to be trivia since they have no reference as to if what he did was notable in any way, i.e a historic first? a well published pathfinder?, etc. Fountains of Bryn Mawr (talk) 20:50, 9 December 2010 (UTC)
