Talk:APS-C

Slight rewrite
I rewrote some parts of the article. The previous version seemed to confuse APS-C bodies that have a full-size mirror, and APS-C bodies that have a smaller mirror. Certain statements (such as the 1.6 focal-length multiplier) applies to all APS-C bodies, regardless of the size of the mirror, while other statements apply only to bodies that accept the APS-C-specific lenses. --Interiot 00:53, 13 March 2006 (UTC)

I just updated with reference to 30D when I found this comment. The 1.6 crop factor certainly *deos not* apply to all APS-C cameras but only to a rather small subset - the entire Nikon family is 1.5 and even Canon has 1.3 ones.szlevi

Upon further inspection I realized that the original article was full of misinformation, so I decided to rewrite and expand it. szlevi

AFAIK all Nikon's and Minolta-Sony DSLR have same sensor, like Pentax; FOV-crop is actually 1.53 194.88.211.202 17:05, 28 September 2007 (UTC)

--- I think in most cases the crop factor is actually something other than exactly 1.x where x is a single precise digit. Wouldn't it make more sense to move Pentax back to the 1.5 line, and then note that all values are really approximate?

Since the nominal focal length values given by manufacturers for their lenses often vary from the actual focal length by a lot more than 1%, the extra precision isn't really very meaningful anyway.

 * Good idea, in my opinion. Also reduce the long list of Pentax cameras, many of which are red-linked.
 * Unless someone objects I think I'll add my Image:SensorSizes.jpg graphic to the article, after converting it to PNG. --RenniePet 16:20, 13 November 2007 (UTC)


 * OK, I've added my diagram. Next question: would it be a good idea to swap the diagram and the picture of the camera? --RenniePet 22:37, 13 November 2007 (UTC)

Many of the Pentax and Nikon cameras listed in this crop-factor list use the same Sony manufactured sensors, which are the same size, and same crop factor......  Someone want to fix that maybe? —Preceding unsigned comment added by 71.210.155.10 (talk) 23:03, 7 July 2008 (UTC)

I found this article very insightful, especially the Brand Designations and the Multipliers.--Zer0Nin3r (talk) 20:28, 26 October 2008 (UTC)

Multiplier factors are overly precise
The Nikon and Sony cameras don't actually have exactly a 1.50× crop factor. It's just that Nikon/Sony don't specify it more precisely in their literature. For example, it's known that the Nikon D40 and Pentax K100D use the exact same sensor... so they obviously have the same crop factor. Likewise, the Pentax K10D and Sony &alpha; 100 use the same sensor, made by Sony. What should we do to remove this deceptive impression of a significant difference in crop factor?

In addition, Pentax *ist D used the same sensor as Nikon D100. Moreover, Canon's CMOS sensors have different size: Canon EOS 50D uses 22,3 × 14,9 mm sensor (1,61×), Canon EOS 30D had 22,5 × 15,0 mm sensor (1,60×) and Canon EOS 10D was supplied by 22,7 × 15,1 mm sensor (1,59×). maksa 11:52, 5 September 2009 (UTC)

Yes, I noticed that the Pentax cameras listed with a 1.54 crop factor (K-5, K-30, K-01) have a 1.52 crop factor. Also, while the first few Samsung NX models (NX5, NX10, NX11, NX100) did have a 1.54 crop factor, most of the new ones (NX20, NX200, NX300, NX1000) have a slightly larger sensor (23.5 x 15.7) and thus slightly lower crop factor (1.53). Add that some of the newer Nikons (D5100, D5200, D3200) have smaller sensors and thus bigger crop factors (1.53, 1.54 and 1.56, respectively), so that "all Nikons" is not quite true. (I did not look at all the Nikon models, either.) Not sure if the list should be rewritten with more models numbers and corrections, or simplified with a lower precision in crop factor and less models? uRubelScum (talk) 00:32, 8 January 2013 (UTC)

The Future of Digital — Full Frame or APS-C?
This link should be removed as is it is questionable. The predictions did not turn out to be true. —Preceding unsigned comment added by 87.123.158.31 (talk) 15:58, 9 June 2009 (UTC)

APS-C and APS-H
The picture provided in the brand designation shows an incorrect ratio between APS-C and APS-H which are the two important sizes in digital photography. As illustrated in the image, the two (APS-C orange and APS-H turquoise) have the same height. Brown is for the APS-P and black is the full frame. The drawing should be corrected to reflect this.

 * I have relayed your concern to commons:File_talk:Sensor_sizes_overlaid_inside.svg. Sorry it took so long for somebody to reply to you. Jason Quinn (talk) 15:33, 12 March 2012 (UTC)
 * We may have to email the tech dept. at Nikon and Canon. They should be able to clear it up.--Canoe1967 (talk) 18:57, 12 March 2012 (UTC)
 * 30.2 x 16.7 are the dimensions for APS-H film, not digital sensors. I don't know why, but ASP-H for digital sensors is completely different. For the Canon 1D Mark III and Mark IV, it's 27.9 x 18.6. See DPReview review of Canon 1D Mark IV. For the earlier Canon 1D Mark I and Mark II, it was 28.7 x 19.1. The illustration in the article is correct for APS-H digital sensors, at least for the last APS-H Canon model. The Leica M8 and Kodak DCS 460 are 27.0 x 18.0 and 27.6 x 18.4 respectively; slightly different than the final APS-H Canon 1D series model but maybe not different enough to warrant trying to show them separately in the illustration. I've never heard of a digital camera with a sensor size similar to film APS-H (30.2 x 16.7). Greg (talk) 20:34, 10 March 2016 (UTC)

Canon Aspect Ratio Info
Not sure where the aspect ratio data came from, but the t6i is 3:2. It's sensor specs are very close to 3:2, and the manual says RAW mode is 3:2. It's resolution is exactly 3:2, 6000x4000.

So where the 1.62 comes from is a mystery to me :) 2601:281:C102:3F40:4103:686B:230B:6783 (talk) 04:55, 1 October 2016 (UTC)
