Well when you quote someone it is nice to read what he was writing I think.

You can jump up and down as much as you want but my comment is correct though.
X-mode will set the shutterspeed to your flash-sync speed, that the Kr or Kx doesn't have one isn't my fault.

I think it's just the matter of convenience. I prefer the 1/3 steps, since they allow me to fine tune the exposure a bit better most of the time.

hehe - Not your fault - the fact that forums can, for some, be a punch bag to relieve their personal hang ups makes them all the more fun. I must go out and buy more popcorn now

I guess nobody noticed my post #4 above, so I'll say it again: On my K20D, with 1/3-stop steps, the EV range is plus/minus 2EV. With 1/2-stop steps, it's 3EV. If you need precision (cf. OBSESSIVE) then use 1/3 steps. If you need range, use 1/2 steps. As mentioned, micro-tuning can be done in RAW development or other PP. Our sensors aren't 'chrome -- they have some tolerance.

Sorry for bringing up the K-r again...I just checked the EV range for both 1/2 stops steps and 1/3 stop steps. Range is 3 EV for both settings.

On my K5 the range is from -5 to +5 and it does not depend on 1/3 or 1/2 choice (same for both)

After reading the camera walkthrough in the K-5 review here on Pentaxforums, I noticed it said to set the EV steps custom function to 1/2 stops vs the default of 1/3 stops. Now before someone starts to explain stops, don't bother, I know well what f stops are. My question is, why would you switch it to 1/2, when the default will give you more precision? Is it that the sensor DR in the K-5 has more than enough exposure latitude to easily cover a larger stop interval? What is the reasoning behind setting 1/2 stops?
Unless you use X mode, you can't get to the flash sync speed with 1/3 stops.

Ah, I was unaware. I withdraw my argument.

Why 1/2 stops? because all Pentax manual lenses are designed with one full click as 1/2 f-stop.

As dynamic range of the K5 and PP options, I use whatever step. Most my lenses are manual anyway.

So then is the 1/3 setting just a marketing tool to "add" a functionality to the camera?

If I am shooting in M and I use the EV scale as a light meter to setup my exposure....if I have the camera set for 1/2 steps is each click of the aperture a doubling (or halving) of light or do I have to click twice for a full stop to achieve this result. Same for shutter speed.

I use 1/3 steps for 10-shot brackets

I like to use 1/3 steps when I shoot two sets of brackets: the first will be all <0, the second set will start at 0 and then shots 2-5 will be >0.

If I'm shooting 5-shot or 3-shot brackets then I usually switch to 1/2 steps.
