ISO in manual mode

Was taking some photos yesterday with my 300mm K mount in manual mode and when putting them on the computer I noticed a lot of noise. Works out that somehow it had got onto ISO 800.
With other modes you can set it to auto and limit the iso but it seems you cannot do that in manual?

Also the lens seem to overexpose quite a bit so I turn the front wheel 3 times to change the exposure to how I want it but to change the ISO I have to use the FN button, is there any way to put it onto the back wheel.

Thanks.

Go into the Custom Settings menu and you will find whatever options there are at setting the front and rear e-dials. Manual mode is not included because you have to have a way of setting shutter speed and aperture and need two dials for that.

There does not seem to be any options for the edial in manual mode.
Seems a bit of a waste as the aperture is set on the lens.

Thanks anyway.

Re K10

As i understand it you dont get auto ISO in Manual at all. Even if you have set 100-400 for auto-ISO when you switch to Manual it will select 100.

If you have the latest firmware you can change the ISO by pressing and holding the OK button and turning the front wheel

That will do nicely thank you very much

As you press the OK button the top camera display will show the current ISO so you can see it change as you twirl the wheel.

I mainly use Av and manual and sometimes Tv. I have set the rear dial to control aperture in AV and shutter in Tv. The front wheel is always set to exposure compensation. When I use manual I have to use front for shutter and rear for aperture, as you discovered you cant change these. When using manual lenses it would be nice to use the rear wheel for the shutter especially if using the DOF prview to activate the light meter. Takes quite a bit of dexterity to hold the DOF lever and twirl the front wheel for shutter control.

I always use the green button to set basic exposure in manual mode (you can specify whether it changes the shutter speed, aperture or both), this will then leave the exposure meter active in case you wish to make any adjustments.

Quickest way I know of setting manual exposure.

I like to use the old M and K lenses on the K10. With these you cant see the meter av bar unless you hold open the dof preview. The green button will set the shutter speed for you , but i like to see my over/under exposure for reassurance.

Ah, didn't know that, as I no longer have any non-A lenses.
