Controversial take:
If they are a capable photographer I believe they should hand it out.
Hear me out: I work in graphic design and illustration for the better part of a decade, I am capable of editing raws myself and I often need to as part of my work.
A photographer not handing out raws is a kill-criteria and makes collaboration difficult. Frankly, I hate it.
I also believe in handing out open files and source material in pretty much any field of visual art.
Remember folks, clients hire your visual talent because of your signature and style (of shooting) + in large parts your personality. If you are afraid a client will walk away with source files and ridicule your work publicly or run off with it to a cheap competitor, than you are not as good as you think you are in the first place.
Agencies I worked for also always gave out files on request.
A complete dust, debris and weather sealed body. To the point I can drag the setup through sand and drown in water and the sensor will never pick up any little particle. Sensor dirt drives me crazy.
