"DX format is very similar in size to sensors referred to by other camera manufacturers (Canon, Pentax, and Sony) as APS-C" - Very similar? It's identical, unless someone provides the proof that it's not. Same crop, same size, same sensor produced by Sony as in other APS-C cameras.... how it is this article imply that it's not identical?
Even sensors within the DX family do not have identical sizes. Canon specifically has 1.6x crop instead of 1.5. Until you can prove that they have identical sensor dimensions to DX format (but even DX format itself isn't consistent) it should stay "similar". --antilivedT | C | G 23:53, 25 December 2009 (UTC)
It's all APS-C - format which also has different dimensions ranging all the way from 20.7x13.8 mm to 28.7x19.1 mm - that's exactly where ALL of the DX sensors fit. Therefore it's identical to APS-C format, not just "similar" - word similar implicates that there are dimensional differences, while there are none. 188.8.131.52 (talk) 14:57, 19 January 2010 (UTC)
