I own the S1R2 and use it for street photography fitted with the S f2.8 24-60mm lens. This lens does not have an aperture ring which means I'm letting the camera choose the aperture for each shot.
I have tried and tried to figure out how to set the aperture myself via the camera body but so far I haven't found how to.
I've searched through the menu and looked to see if I can assign a scroll wheel to control it but…

The easiest way would be to set the model dial to A (aperture priority) and then spin the control wheel on the top right hand side of the camera.
 
Yes, I have tried to "use the dial" on the top, and I know I can shoot in aperture mode but I shoot in shutter priority to keep the camera from choosing a low speed.
I normally stay on 1/250th for my street work, so I don't mind the camera picking a high ISO if it decides that what it needs.
There must be a way for a user to change the scroll wheels to whatever he/she wants? both control the shutter speed but can't be changed... why?
This seems to be a Panasonic/Lumix issue as my previous Sony @ and Fujifilm cameras let me chose one dial to do aperture and the other, to change shutter speeds.
I had this same issue with the S9 and had to shoot in aperture but that was mainly to get around the problem of the rear scroll wheel being a nightmare for accidentally changing the shutter speed.
 
Yes, you can change what the wheels do. Look for a sub-menu that looks like a wheel.

Also, sounds like you should be in M mode. That way one wheel controls the shutter speed, and the other the aperture.

Because I never use the WB button for WB I reassigned it to minimum shutter speed.
So I can set it to 1/250 for example. What the camera then does while in A(perarture)mode is that it keeps upping the Auto ISO until it hit max-iso and only then starts lowering the shutter speed.

Default minimum shutter speed is Auto I guess. Forgot. But it’s Photo->Exposure->Min shutter speed.

Really like to use this; works very very good. Static stuff in museum 1/15, people 1/125 etc.

Er… when you set to Shutter priority, the aperture is deliberately made to float to reach the EV you set with the Exposure dial. That’s what Shutter priority means. You set the shutter speed and the aperture is adjusted to meet the selected EV; just as with Aperture priority, you set the aperture and the shutter is adjusted to meet the EV.

If your main priority is to keep the shutter from dropping below a certain speed, you can use the Min Shutter Speed setting and shoot in Aperture priority:


Or if you want one dial to adjust shutter and the other aperture, then shoot in Manual as others suggest.

Yes, you could be right. I'm not
 
Okay, thank you for all your suggestions and answers. Very much appreciated and helpful too.

On the RH control dial set to "M" and use rear dial for shutter (default setting) and the front dial for aperture (also default) and ISO at auto. You will have complete control over everything and if you do want to mix it up (assuming you have the light and think you're smarter than the camera) just press the ISO button and scroll away!!
 
In M mode the front dial changes aperture. In A mode too. In S and P mode the back dial changes aperture. It is how came the camera new and not used from the shop. At least in my case.

But, you can configure to your liking if you go in the menu to the: wheel / Dial Set. / Assign Dial (F/SS) and there you have from SET1 to SET5 to assign them as you like.

Use the manual mode in combination with Auto ISO.

And EV compensation then controls auto iso? :cool:

But all these suggestions are better then S mode and giving up on control of aperture. I think that P works as well with minimum shutter speed and auto iso. The camera then lowers aperture first, then Iso. When the camera hits minium iso it will then increase aperture,

Or A mode with Auto ISO and a suitable minimum shutter speed set.

That was my first answer with instructions, and how I use my cam. :cool:
 
I shoot almost exclusively in A mode and have the rear dial set to control aperture (if the lens doesn't have an aperture ring) and I have the return button on the back set to control the minimum shutter speed allowed, which I change based on circumstances. That setup is extremely flexible and sounds like it's just what you need.
