In many other threads, users of the K3 (the professionals) have stressed that the K3 can easily give the same IQ as a FF aka Nikon/Canon FF
So surely Pentax users can't really be wanting a Pentax FF only to be able to use their old legacy glass?
What other benefits would the Pentax FF actually offer ?
I don't think anyone says that there is no benefit to full frame, they just say that the benefits come at the expensive of more shallow depth of field. For many types of photography, like portraiture, this is not a problem and can even be a benefit for the photographer, but there are times where you do need maximal depth of field and you are less likely to see benefit from shooting full frame there.
I think the biggest problem that I personally have is when folks show up and say that their full frame camera is two or three stops better than their APS-C camera was. The reality is that there is a little better than a stop difference between current generation crop and full frame cameras with regard to noise and dynamic range (D7200 actually matches some Canon models in dynamic range) -- that is a very real difference.
The biggest reason that people want full frame is exactly that -- want. I don't need full frame, but I do want it. I have a lot of full frame glass and I think it would be fun to have a new body and play around with it with the FA limiteds and the other lenses that I have that will work on it. And I do think there are plenty of other folks out there who will be interested in it as well if the price is right.
