Complete list of sensor sizes & Circle of Confusion...

Post by ofarcis »

Hi to all,

I made a list of sensor size and the circle of confusion of some reflex cameras but I don't find some:


- Circle of Confusion (CoC) of: Canon EOS 6D, Canon EOS M, Nikon D600 and Nikon D5200.

- Size in milimeters of the sensor: Olympus E-1, Olympus E-300 and Olympus E-500.

Thanks for your help, Oscar.


You can see the complete list then:

Oscar,

Thank you for assembling this information.

In general, sensor sizes can be obtained by looking for a review article. The web site http://dpreview.com provides reliable reviews.

For example, the Olympus E-1 sensor size can be found by Googling on
Olympus E-1 sensor size dpreview
to find a link to http://www.dpreview.com/reviews/olympuse1 . The sensor size is shown on page 2 of the review as
17.4 x 13.1 mm active sensor area
I have a couple of concerns about what you have assembled so far.

1. For Olympus, the numbers that you show are not consistent.

For example you show:
Olympus E-3 18 × 13,5 0.015
Olympus E-30 17,3 x 13 0.015
But dpreview shows that the E-3 and E-30 have the same sensor size: 17.3 x 13.0 mm active area. (References are http://www.dpreview.com/reviews/olympuse3/3 and http://www.dpreview.com/reviews/olympuse30/3.)

The issue is that there are two different sizes: 17.3 x 13.0 for the active area, but 18 x 13.5 for the full sensor. The full sensor is bigger than the active area because it includes pixels used for other purposes. You have quoted the active area for some cameras, but the full sensor for others.

2. Please be aware that the "circle of confusion" is not a fixed number. Instead, it depends on the viewer's tolerance for blur, which in turn may depend on pixel size.

For pixel-peepers, the CoC definitely depends on the pixel size. For a pixel-peeper, the acceptable CoC for a Nikon D800 (36 megapixels in full frame) is only about 0.58 times the CoC for a Nikon D3 (12 megapixels in full frame).

You can automatically take pixel size into account by calculating the CoC as follows

CoC_pixels = 3 (or some other number, to satisfy more picky or more tolerant users)
PixelSize_mm = SQRT(SensorWidth * SensorHeight / PixelCount)
CoC_mm = CoC_pixels * PixelSize_mm

For example:

Canon T1i, sensor size = 22.3 mm x 14.9 mm, pixel count = 4752 x 3168.
PixelSize_mm = SQRT( (22.3*14.9) / (4752*3168) ) = 0.004698
CoC_mm = 3*0.0047 = 0.014

The numbers that you have used are roughly equal to 4 pixels per CoC, for modern DSLRs. These are a little too big to satisfy pixel-peepers. For the D800, your number is 6 pixels -- quite a lot too big.

It would be better, I think, if your table focused on sensor size and pixel count. From those, CoC can be computed as described above.

Thanks Rik and Chris S. (in private messages).

My final goal is to apply the Lefkowitz formula to calculate the Deep of Field (DOF). (http://www.photomacrography.net/forum/v ... hp?t=19755).

I like to apply this formula to calculate approximately the number of steps (stepper motors) to focus the object from initial point to end point.

I know from my app the resolution of the camera configured for the user and I can calculate the CoC from your formulas (http://en.wikipedia.org/wiki/Depth_of_field#Close-up_2).

Yes, i think finally that the table have only the sensor size and calculate the CoC dinamically because the user can change the resolution if any moment.

The camera not returned me the size of the sensor :-(

dpreview.com is a good page to get the specifications of cameras.

Thanks, Oscar.
