ISO AUTO in M and the first impressions

In K-30 there is a surprising option in M, you can set ISO to AUTO but Green Button will not perform Stop Down metering with manual lenses.
After downloading the pdf manual I have discovered that:
"If the mode dial is set to M when the sensitivity is set to [ISO AUTO] , the camera operates in TAv mode."

Turning the LCD off is a bit fiddly, you can not just toggle INFO button like you could on Q, K-x,K-5&K-7, it requires few more steps.
Magnifying in Live View is again a bit confusing, all those matters could be easily fixed with firmware update.

Camera is well build but it feels much more like K-x/r than K-5/7, IMO the MENU button is too close to WB ( four-way controller) , I keep entering the MENU instead of selecting the options but I am pretty sure I will get use to it.
It should definitely be supplied with AA adaptor as a standard accessory.I had plenty Eneloops ready to go, I had to wait for hourd for the charger to charge the supplied rechargeable instead, before I could turn it on. My AA adaptor on the back order.
Nevertheless K-30 is an another example of excellent Pentax engineering indeed.

I'm not sure it is a good or bad thing that it's possible to use auto-ISO i M-mode when there is TAv mode on K30.
And as exposure compensation is not available in M-mode, it is not as flexible as TAv-mode.

So I might be a little confusing.

i_trax, I am having trouble getting a non A series manual Takumar to stop down. I was told if I turn off the auto iso that would allow the camera to down stop when the picture is taken. Trouble is that having done a fair amount of looking, I have not been able to find out how to turn off auto iso. Would be much obliged if you could provide the steps. Then, if I understanding correctly, when I take the picture the camera actually actuates the aperture to the f stop I have set the dial on the lens to?

Auto ISO has nothing to do with stop-down metering AFAIK. Here are the steps you need to follow in order to get it to work:

Just select an ISO speed setting other than "Auto".

Screw mount lenses will not auto-stop down on any Pentax K-mount body. You have to manually stop them down. To do this the auto/man switch (if there is one) should be set to "Man". You can use this to pre-set your f-stop and then go wide open to focus/compose by switching it to "Auto". Metering and exposure should be done with the switch set to "Man".
