My one and only ergonomic gripe about the K10D/GX-10 is the lack of a dedicated ISO dial.

Isn't there a way to reassign one of the e-dials for iso?

Wow! What a view, and the colors are spectacular.

Agree - nice!

Paul is correct! ISO can be mapped to either e-dial. Menu 4 of the "C" (Custom Setting) tab. That is how I have my K10 set up, ISO on one of the e-dials. I think the default is EV compensation, but since there is a dedicated button for EV comp, ISO on an e-dial is a suitable substitution for me.

Thanks guys, but as far as I've ever been able to tell you can only set one of the wheels to ISO when you're using an autoexposure mode. In manual with an autofocus lens it uses one wheel for shutter and one for aperture, and with manual lenses it just uses one wheel for shutter and leaves the other doing nothing.

That's how it works on my GX-10 version anyway. If the official Pentax version does dedicate a wheel to ISO in manual mode with manual lenses, that would be a good enough reason for me to switch.

It seems like a real oversight by the firmware designers. When you're using a lens with its own aperture ring, why not default to one wheel controlling shutter speed and the other controlling ISO?

Yeah I just saw that the e-dial is not programmable during M mode, and I'm in the latest firmware. That is a bummer. As you said, in M mode the dial just doesn't do anything. It does look like an oversight.

The K20D fixed that, it used the same e-dial setting for TAv and M modes (just checked the manual to confirm, since I haven't had the K20D for over a couple of years now... I set it so the dial would be ISO but then I ended up not using it that much).

I never remember what the e-dials do. I'd be afraid of changing the iso by accident and shooting pictures at a different iso than I wanted because I thought it was something else. I understand, of course, that using an e-dial to change iso might be handy for others.

I also had trouble riding a 10-speed bicycle, discovering that I had a 3-speed brain or was it 3-speed physical coordination.

Gave my original K-10 to daughter, and she gave it back because the screw (as in AF screw drive) is no longer screwing. I will use it for my Takumar 50 and 55 lenses. I have never been get them to auto-focus anyway, screw or no screw.

Oops. I forgot about manual. I guess that is the price of doing it all yourself

Better than film days, though, I'm sure you remember: Changing ISO meant changing film!

Of course, I am sure that the GX-10 is not identical to the K10D....in AV and TV modes I have customised the front wheel to ISO but in P and M modes if you press the OK button that puts you into ISO mode which can be changed by turning the front wheel. Does that work for you, Dave? Is that what you were looking for?

I mainly use manual focus lenses on my K10D and my K110D. Since I got my K-R, I've mainly used autofocus lenses on it, and have added a few more AF lenses to my collection.

Ray, you're a genius! I'd never heard about that functionality, or ever seen it in the manual anywhere, but it does indeed work on the GX-10 version too. Hold down the OK button in manual mode and the front wheel changes ISO!

You have my deepest thanks, my friend.

It is my pleasure to be of assistance to you, Dave. It is in the K10D manual but it doesn't actually scream out at you. I have read that manual time and time again and I eventually found it. I can see you making great use of that "feechur".

Why I love Pentax Forum!

Wow, I read and read and read my manual, now I hear there are tricks I can do that aren't documented? I have the K-5, in M mode I know how you change ISO, but now I'm thinking there are some hidden gems like this for me too. Cool.
