Background Focus with Jpegs vs RAW

I am curious about how the Auto function to adjust the background focus works.  The function is only available when Quality is set to jpeg (e.g., Fine) and not for RAWs.  But adjusting the background focus is a function of aperture, distances and focal length, so why is it not available for RAW files?  I mean, one can certainly do that manually in P or Manual modes (adjust the aperture that is). so does that mean that the Auto function is adjusting the background focus some other way (e.g., post processing)?

Background Defocus is a Post Processing feature.

 

By definition: Raw + Post Processing = JPEG

 

Please see http://www.dpreview.com/forums/thread/3469509 for more details    ;)

 

 

 

Edit: If you are shooting RAW and want to defocus the background, open the aperture (smaller F number i.e. go from F 8 to F 4 to increase background blur). The increased Blur will be recorded in the RAW file.

      2 Primes or 1 Zoom?

      By XKAES · Posted

      I'd opt for a small zoom, but I must admit that there seems to be a dearth of lenses in the e-mount in the 24-50mm range -- for some reason.  I have a small 24-70mm, but that's an a-mount Tamron.  Maybe you can find something by looking at lenses slightly longer.  I have a heavy, but small 24-100mm a-mount, and Tokina made a 24-200mm a-mount.  Maybe there are similar lenses in the e-mount.  Kill three birds with one stone.

      Well this! Thank you! I have been following suggestion after suggestion for the past 3 hours with my a7CR and never thought of removing the battery. Magic!

      2 Primes or 1 Zoom?

      By bs.shoots · Posted

      I recently got an a7cii and to pair with the compact body, I thought of getting 2 of the trio compact lenses, 24mm F2.8 and 40mm F4.0. (I already have a 70-200mm) However I stumbled upon the newly released 24-50mm F2.8 G. I'm not sure which to get - I like the small factor of the prime lenses ON the body because it's discreet and helps me blend in as an average tourist / doesn't make it obvious when doing street. But if I add the dimensions of the 2 primes together, it takes up more space in the bag than the zoom lens. BUT THEN, the weight of the 2 prime lenses is 110g lesser than the zoom lens. The zoom lens has the added benefit of being more versatile.   So now I'm stumped. Each has their pros and cons and I can't decide which to get. I'd like to hear the views of you guys who are more experts at this.   Edit: I'm a bit concerned about weight because the last time I went overseas my shoulders were aching from carrying too much. Which is why I was looking for small compact primes in the first place.
