Agree photo journalists and sports photographers do tend to shoot in jpeg and usually have their cameras set up with wi fi for transmitting images on the fly.I would agree, there is a lot more leeway with editing images shot in RAW however, when shooting 3,000 plus images a day, over 3 or 4 days at a PSP or Millennium event can you imagine the amount of storage needed, Especially when shooting at 20 plus MP. You can still make minor adjustments and even add border and filter effects to Jpeg images, but, why would you want to, if you have got it right (or close to) in the first place?
When I shoot Pro cycling, TDF, Milk Race, etc, the agency stipulate Jpeg, these images are syndicated the world over, often in a matter of hours, little or no post editing needed!
For me its a hobby and shooting raw is fine for my needs because I don't have that many files to deal with.
Amy my set up at the moment is Nikon D3 and Nikon D700. My lens choice is 24-70mm f2.8AFS, 80-200mm f2.8 afs II, these are my workhorse lens for the paintball field. I have a magnified eye piece cover for the viewfinder to compensate for the distance i lose from wearing a mask while taking shots.Its still a learning curve for me as I tend to shoot wide open at f2.8 but have auto iso enabled. The photos I posted up from the masters were taken on a bright sunny day. It enabled me to shoot low iso setting with fast shutter speeds and it helped with my D3 set to continuous 11fps
