Confused over sensor specs

[maxxremis]

I have a Nikon D5100 camera.
When I look up the specs on this camera, specifically the sensor, it says, “ 23.6 x 15.6 mm CMOS sensor”.
When I try to set up the Depth of Field calculator, the choices for camera type are:
Digital SLR with CX of 1.6X, 1.5X, 1.3X, and 4/3” sensor.
My problem is how do I convert my spec reading of 23.6 x 15.6 mm to the CX listings.
Thank you for reading.

CX is a particular Nikon sensor type, used in the Nikon 1 series. That confuses things a little.

Your required setting is probably 1.5X.

Now that is what I call a really fast reply! Thank you so much, Gorf. I do appreciate it.

You're very welcome.

I know nothing about Nikon cameras, but a 35mm "full frame" is 36 x 24 mm, or 35.8 x 23.9 mm. See the table at the end of this: https://en.wikipedia.org/wiki/Image_sensor_format. That means that your camera has roughly a 1.5 crop factor, so you would use 1.5X. Or just enter the camera name into this: http://www.dofmaster.com/dofjs.html
