Sensor Sizes and Pixel Dimensions Compared

[gonzalu]

I was bored and also spending too much time thinking about the relationship between the different files and pixel dimensions offered by the current Nikon cameras and some competing products from Canon and Sony. So I put together a quick file using the pixel dimensions of each camera and overlaid them on top of each other for comparison.

Feel free to comment or make suggestions for improvement. I will consider them and revise accordingly. Hopefully someone finds it useful.

The file comes as a PSD with text labels and images on different layers. Each camera is represented by a colored rectangle in the native resolution with an actual sample image from the manufacturer when available.

Here is a look at just the blank rectangles



Here is what the sample images look like when all layers are activated.

So, this would be like printing an image from each at a specific dpi and comparing print sizes, right?

Thank you gonzalu! Appreciated..

Hmmmm... It was possible to assume that the linear difference of 1.4X between the M9 sensor (or the D3x) and the 36MP one could not be that significant however after seeing the total area one can figure out that the new sensor is more into the MF category.. Nothing in the 35mm format can come close to it.

Regards,

Bob

looking at it to figure out what the pixel dimensions are in relationship to each other. It ignores actual sensor size and pixel pitch at capture. All rectangles are normalized to 72dpi.

My use is for my type of need. I guess you could enable the layers on or off and then change the overall DPI of the file and print or test... Whatever suits the needs of someone downloading it. Do you have any ideas how you could use it otherwise? I was thinking of making one similarly that takes the sensor size/pixel pitch into consideration...

of what it would look like next to the Canon 7D and Nikon D7000 at DX crop mode. I love the fact that the Sony CRAMS the 24MP in the center of the frame which is A LOT of pixels on-target ... I can use that in my type of photography (small subjects at a decent distance)

400mm on a 24MP APS-C and on an 16MP APS-C can give much more detail in the resulting image. To use the greater 36MP of the D800, I have to get closer to my subject to match what I can get from an APS-C sensor on Sony at the same distance.

nice.. submit it to wikipedia

I agree it's nice, but the current Wikipedia is not particularly beautiful, but it has many more sensor formats like APS-H (Canon), Foveon, m43, and all the P&S sensor sizes like 2/3", 1/1.7", 1/3".

Wikipedia's Sensor Format chart
http://en.wikipedia.org/wiki/File:Sensor_sizes_overlaid_inside_-_updated.svg

Wikipedia's Article on "Image Sensor Format"
http://en.wikipedia.org/wiki/Image_sensor_format

You might consider using colors for each format, and you could add other formats, as long as the diagram doesn't get cluttered, which is a distinct possibility.

It does give a nice feel for the difference in scale. The reactions of the museum goers is priceless.

Thank you

Thanks to Robin for some of the data

Visit my website for the full PSD with sample images which you can use for comparing dimensions and editing and wokflows etc. WARNING, large files!
