Question about differences in focal length equivalencies and depth of field

[Panza]

Hi, If I have a 35mm DX Lens on a DX camera I will have a FoV of 52.5 (~50mm for ease).

What are the differences between using a 35mm DX on a crop sensor camera and a 50mm on an FX camera. Are there any differences in the depth of field/bokeh that I will get?

Thanks,

Pan

This is a 30 vs 50. It shows the differences.

Oh wow, I tried to look at it, but it was blocked at my work place because it was considered pornography. ... I will have to check when I come home.

I found a comparison of a 50mm DX vs an 85mm FX but not a 35 vs 50. I can tell there is a little more blurring of the subject. I can see some compression differences too but I'm not sure if that's because it's 75mm equiv. vs 85mm?

The 35mm/DX combo will provide more DOF and less Bokeh at the same distance and FOV as a 50mm/FX combo. Here a basic comparison at 1 meter using f/2

	All in Millimeters
	DX Sensor	FX Sensor
Focal Length	35	50
Focus Distance	1000	1000
f-number	2.00	2.00
Circle of Confusion	0.02	0.025
Depth of Field	63.08	38.01
DOF in front	30.55	18.65
DOF in Rear	32.54	19.37

You answered your own question with the 85--50 comparison. It's basically the same for the 35-- 50 Fx gives you less DOF.
