<p>Hi!<br> The difference between FX and DX is a topic that can puzzle any photographer, even me ;)<br> In this case I want to figure out the exact difference in depth of field, noise etc and how it will effect the image for video in a low light situation? As an example I want to compare the Nikon D750 with the Nikon D7200 with a crop factor of 1,5.<br> Of course you would think that the Nikon D7200 will give more noise in a low light circumstance but will it still be the case if you can adjust the aperture to get the same depth of field and lower the ISO? <br> <br />Here is an example of two different gears and settings:<br> Nikon D750<br />Focal length 24 mm<br />Shutter speed 1/50 s<br />Aperture f/8<br />ISO 3200<br> <br />Nikon D7200<br />Focal length 16 mm <br />Shutter speed 1/50 s<br />Aperture f/5,6<br />ISO 1600</p> <p>In my mind this would give the same result but is this correct or am I missing something...?<br> Here are my simple calculations:<br> 24 mm = 16 mm for a DX sensor (24 / 1,5 = 16)<br />f/8 ≈ f/5,6 in depth of field for a DX sensor (more exactly it should be 8/1,5 = f/5,33<br />ISO 3200 ≈ ISO 1600 for a DX sensor (more exactly it should be 3200/1,5<em><sup><em>2 </em></sup></em>= ISO 1422)</p> <p>Will the footage look the same or will there be any difference in noise, brightness, depth of field, dynamic range etc? <br> (sorry for any grammatical errors, I am not a native English speaker)<br> Cheers!<br />//Daniel</p>
