Reference for 24mm on 35mm-format being "ultra-wide": http://books.google.com/books?ei=IxyITYW0BIagtwfQ--H8DQ&ct=result&id=0H1qAAAAMAAJ&dq=28mm+%2Bultra-wide&q=below+25mm#search_anchor

Yes, but that reference dates back to 1970 and also states that >200mm lenses are extra-long. In this case a forty year old citation perhaps doesn’t quite seem to cut the mustard. (I think of my 21 mm lens as being usefully wide angle, and of my 14 mm lens as being one to use with an extra degree of care.) Ian Spackman (talk) 16:02, 22 March 2011 (UTC)Reply

Cameras on Mobile Phones edit

How do Ultra Wide Angle Mobile Phone Cameras, with an angle of view of 130° or even more, work? That's like 1 or 2mm focal length--95.90.20.115 (talk) 20:10, 8 July 2019 (UTC)Reply
