Wikidata:Property proposal/Objective

Description	Indicates the camera lens item used by the photo or video camera (subject). It can also be used in a photo item to indicate the lens used to take it. In the case of telescopes, they do not incorporate "a lens", but are themselves a lens understood as "the optical element that collects the light from the object being observed and focuses the light rays to produce an image real".

We are missing several properties on the subject of cameras; this, along with frame rate, Wikidata:Property_proposal/Image processor, Minimum_focusing_distance, Image stabilitzer ...., is a typical photo and video feature.

Currently the lenses have their own item. But there is no property to bind the camera to its lens.Amadalvarez (talk) 22:42, 20 December 2022 (UTC)[reply]

Wait Wikitext is not available in descriptions. Please change the description to remove the template formatting. The name of the property should likely more specific so that a user doesn't mistake it for being about objective in the sense of a goal. It's unclear why the property isn't named lens. Lens sounds to me like it's easier to confuse. Are there reasons against calling it lens? ChristianKl ❪✉❫ 09:27, 23 December 2022 (UTC)[reply]
Comment ^ Perhaps a more specific name would avoid confusion with has goal (P3712). -wd-Ryan (Talk/Edits) 20:04, 23 December 2022 (UTC)[reply]

@ ChristianKl, Wd-Ryan: Done, a) changed wikitext; b) changed name to camera lens (proposal page name is not changed until you agree with this new name). BTW:objective (Q3880557) was the "subject item"; I changed it to camera lens (Q192234) to avoid meaning misunderstanding. If you're OK, I'll rename the page. Thanks, Amadalvarez (talk) 14:03, 26 December 2022 (UTC)[reply]
Thanks, this is a lot more concise, and no need to change to move the proposal page. Support -wd-Ryan (Talk/Edits) 17:11, 26 December 2022 (UTC)[reply]
