M mode on RX100 and Auto-ISO

[froyd]

Is there a technical/logical reason Sony does not allow users to select Auto-ISO when shooting in manual mode?

I don't have any other digital cameras to compare it with, but I cannot think of a reason why the function would be disabled.

For my use, it would be very useful for the camera to maintain both the aperture and the shutter speed I set in advance according to my requirements, and maintain proper exposure by switching the ISO speed within a range selected by the user.

Do this make sense?

I guess manual doesn't equal auto. Sony has some other bizarre functionality... But I live with it.

I agree entirely. I can't see why this function is generally not provided by camera manufacturers. The only camera of mine (and I have/have had far too many!) that has permitted this is my Fuji x100. It's a pity that this option was not available on any of the various Canon, Sigma, Panasonic, or Sony cameras that I have owned.

However, despite this omission from the RX100, I have to say that I'm really rather impressed with it. 🙂

Oh, me too! I'm a harsh critic of this little machine only because I like it so much for the results it gives me 🙂. Were I indifferent, I would have sold it already!

Shot my son's birthday celebration last night and was able to capture candle lit images that have no business coming out of such a tiny camera!

My intuitive answer would be manual means manual?

I do get your point, but we weren't suggesting that full manual mode should be omitted - simply that the additional mode should be included.🙂

The point, really, is that since exposure is a combination of the three variables i.e. shutter speed, aperture, and ISO, and partial-auto modes are routinely available to the user:-

• aperture and ISO set by user: camera sets shutter speed

• shutter speed and ISO set by user: camera sets aperture

Therefore it would seem just as logical to provide a mode in which the user sets shutter speed and aperture, and the ISO is then computed by the camera.

Fuji evidently agrees, as this is available on the x100...😉

"That" was the setting I was trying to find on the first day I bought RX100. Then I gave up and have been using the green i mode since.

In Program Mode with the Program Shift function on, when you get something in your sights, you’ll see shutter and aperture settings that you can somewhat control with the control wheel. “Somewhat” because as you move the aperture, the shutter speed rises or drops, correspondingly, to keep things looking good, AND you can use the control ring to change the ISO. All in all, the camera lets you construct the image pretty fluidly as you monitor the image and settings through the screen. I like these options; perhaps you’d find this setting useful if you haven’t already tried it.

The screen is my big problem. I haven’t learned to quickly assess what’s on that tiny screen that I’ll being taking a picture of. I think that just means I need stronger reading glasses, although it’d help if the screen could tilt. I’ve wondered if I had the brightness set at it’s highest setting...Putting it on maximum brightness at the toolbox menu on the Manual > LCD Brightness setting makes it better, but still I have to hold the screen so far away to focus, the image is just too small to get a good look at... Oops, time to get dressed for work.
