There are other factors

Aug 12, 2019,12:03 PM
 

If you really need ultra  wide angle images--- there are advantages to full frame. 

There are other factors -- pixel density becomes an issue for high resolution images. 
NOt all pixels are created equal... so that is a separate variable. But with smaller sensors the 
pixel density, size of teach pixel, and total number of pixels become more limiting. To put more pixels in a smaller sensor means 
a smaller size to each pixel and this will increase noise and other factors. . If you maintain the same pixel size this means less pixels 
and therefore in general less maximal resolution. 

Also as you mention the apparent DOF and the what one can do with background blur (called Bokeh) is more limited with the smaller sensors

For many  these factors might not matter... 
Clearly if you are buying fulll frame you will need more expensive lenses to take full advantage but again it is what is needed for the individual

Crop vs. Full Frame Sensor...

 
 By: cshimokita : August 12th, 2019-05:50
It's the new film vs. digital discussion... not really as it's a no brainer. Technology has reached the point where in many cases a crop sensor makes sense from a financial and quality point of view. Full Frame refers to any camera with a 24x36 mm sensor....

Sensors keep improving

and that includes those smaller than FF. But as with film cameras resolution generally improves with a larger sensor (or neg). With most folks never enlarging an image larger than a computer screen that FF advantage might be less nowadays. DOF is affected...

The depth of field can be determined by focal length, distance to subject, the acceptable circle of confusion size, and aperture. The approximate depth of field can be given by the following formula: DOF ≈ 2u 2 NC / f 2 for a given circle of confusion (C)...
