precisely not, I cannot control set the auto-iso. it's bloqued on manual iso, it's a good exemple of "I cannot control everything" something is not available.
Control everything means I can set as I want, not as the camera maker want me to.
On Nikon, manual mode let you use exactly what you want you have a real full control, with Pentax you canot control the use of auto iso or not... Full control means let you choose yourself what you need, not let the menu tell you what you need.

Originally posted by stevebrot I pulled this over from your introduction (BTW...Welcome to the Pentax Forums!). When using adapted 67 lenses you will not enjoy the full capabilities of the camera. In short, you will be restricted to Av and M modes with center-average metering. Of those, only Av may be used with auto-ISO. There is a lens compatibility table in the Operating Manual. In the English version, it is on page 28.* If you need to control the shutter speed, you will be be using M mode; there is no workaround with adapted 6x7 lenses.
Your option is to consider purchase of one or more lenses made for use with your camera. The A645-series offer good value. If that is not possible, M mode with manual ISO is quite do able, though the approach is old-school, like on your 6x7, only with the option of a quick change of ISO if needed.

* The manual is poorly written and not very clear is some places. If your camera came with the Japanese-language manual, you can download the English versions from...

I understand your explanations.
It's just that, this feature is possible, I don't ask the camera to read the aperture, just want it to let me use auto-iso and set the shutter speed or a minimum shutter speed at least. The camera can use AV, that means it adapt (the iso in autoiso for example) to fit my exposure compensation or to get the right exposure, I just want an auto iso mode allowing me to set my shutter speed.

Thank you all of you for your opinions and helping me how to find out.
The only possibility I see for nom is to take the advantage to set a high iso on manual mode to have a chance it doesn't get too low... the problem is, I'm used to set quickly 1/20 to get a little bit of visible movement, 1/250 to fix the action, and more while I want to make panning shots... That's a bit annoying to know that the camera CAN do it but the menu ergonomy doesn't allow me to set it up.

Originally posted by stevebrot That is generally a good clue that the camera cannot do as you ask.
FWIW, this sort of question comes up frequently on this site and the short answer is that your camera does not have a way to set a minimum shutter speed and attempts to do so using auto-ISO settings will be ill-fated (i.e. does not work as one might think). This is true regardless of what lens is being used. I don't do much street work at present, but when I do, it is always done in full manual.

Street photography production is made in a lot of different ways, me, I need versatility, shoot quickly and get a the right exposure, changing with the front (or rear) dial exposure, have my lens aperture set on a specific aperture, and auto-iso. I'll quickly make it darker or lighter using exposure compensation dial.
