This is kinda schisophrenic, to put some of settings in manual mode to auto mode, and then still with manual mode wanting other settings to compensate for this mixture. You really don´t know what you want, right?
You can do what you want in AV or TV modes. With manual, you are in charge, you have nothing to compensate, and if they allowed some glitch or stupid customers request of auto ISO at manual mode, than it will be everything messed up.
Couldn't disagree more. M mode with Auto ISO is like aperture and shutter priority. I select the DoF I need and the necessary shutter speed to stop (or show) motion, and I get a metered exposure in rapidly changing light. Being able to apply EC to bias the metering is plus.
No, I actually understand your needs, would be happy to have this program in machines, but why in the world should this be in Manual mode? Manual is called manual, because it actually IS manual. I´d add your needs to some other program. Messing it all with EC + auto ISO is really wicked to want in manual mode.
And why not remove the metering indicator and focus confirmation in M mode while we're at it, eh? Hey why not have it disable ALL electronics while in M mode after all it should be pure manual, right??
This is very low. You're making it extreme. I just want it to work as manual program. The metering is there to show what camera thinks of the scene. Not what you have to do. With manual mode and even other modes I rely more on histogram than on exposure meter. Automatic is not manual any more. It deserves to fall under program mode.
Simple solution for you – don't set the ISO to Auto. It's not like that's mandatory. Since Auto ISO is available in the other modes, why not M? Or perhaps do away with Auto ISO...like the good old days of interchangeable sensors, a different one for every ISO and WB, and a limited number of exposures per sensor. What was that called again?
Film??? My first 35mm camera, about 1956 or so, was manual...to the point that it didn't even have a light meter nor did I, at the age of fifteen, own one. Every picture was made by mentally evaluating the scene. And it is surprising how many keepers I got.
