<p>Good point about the 1,3x crop Ilkka!<br> About the 60 fps, well even though the panning will look nice don't you think that it's better to stick with 30 fps because you will get shorter shutter speed and therefore lower ISO and less noise? </p>

<p>Thanks guys for all the answers and opinions =)<br> Since in my example with the Nikon D750 and Nikon D7200 are from about the same generation of sensors and I believe both cameras use the whole sensor for recording video my assumptions seems to be correct. I don't need to get into tiny quality differences for this case, just the overall theory =). And of course there are other features that matters for video like the ability to adjust aperture without turning off live view, power aperture, auto focus, flip screen, bit rate etc etc. The important summery for me is that there is no major advantage in using a full frame sensor for video if you don't need a short depth of field. <br> If you are curios what's this is all about it is for shooting real estate videos. No high end productions but we are using 3-axis gimbals and some other gadgets. We also shoot stills off course and I am using a Nikon D600 for myself and it works fine for these productions. Just a bit annoying that I have to turn off live view to change aperture in video mode, but that's not a deal breaker since I am not filming every day. </p>

<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>^{<em>2 </em>}</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>
