p.1 #1 · 5D3 has auto exposure in M, I never knew!


Embarrassing I know, but it never came up before and hasn't worked like this on any of my other cameras, but I just found out if you set the Shutter Speed and Aperture manually with Auto ISO the camera changes the ISO to what it thinks is a correct exposure!

OK, no exposure compensation but with skilful use of the metering mode (spot mode perhaps) this will be very useful.

Amazing what you can find out if you look

Whoa, this has been a bug bear of us for ages and as far as I know all the cameras do it, certainly 7D, 1D III/IV/X do this. It's absolutlely pathetic Canon refuse to fix this in a simple FW upgrade.

Fix it? It's brilliant

I think Pixel Perfect is referring to the lack of exposure compensation in this mode?

That is what Auto ISO means. OH: And yes, the lack of compensation makes it basically useless. I do use auto ISO on my Nikons though.

Sadly it's pretty much useless without EC I don't want shots which are under or over exposed.

It was one of my points back to Canon in my feedback to them. They just crippled it. They clearly didn't have photographers check the feature out or they would have got the same feedback as I gave.

Really annoying as it's much more useful than the other modes in many circumstances

I believe that this is the way that it works on the 6D too although I haven't tried it.

On the 1D Mark4 and 1DX, there is exposure compensation available in 1/8th of a stop increments up to one full stop either way! You'll find it in Custom Function settings, Exposure and it's called AE Micro Adjustment!

I forgot to say that, when your looking through your view finder with this function set in Manual Mode you EV scale will still read neutral! But it does work, and works well!

Yes.

If you choose the metering method carefully it would be useful.

And no, it's not what 'auto ISO' means.

Not having it limits the situations that you can use it in.

Yes, of course it does but it's a feature I didn't even know the camera had until today, it's not the way I usually work.

There will be occasions when it, together with RAW for some exposure latitude might be useful.

Yes, but this is more like a tuning or calibration function for when you feel the camera's meter needs adjustment (like lenses and AFMA). The EC that Pixel Perfect and Phil are talking about would allow quick tweaks via the scroll wheel without requiring you to take your eye off the viewfinder and enter into a menu setting. Correct me if I'm wrong...

You'll forgive me if I wait for one of the people who mentioned lack of EC to clarify whether I understood correctly or not. Especially since your reply didn't explain why I am wrong in my understanding.

There are ways to take full control over the exposure when using Manual Exposure and Auto ISO on 1D-series, but it requires a bit of setup:

I know some people would rather poke their eyes out than having to use a convoluted solution like this, but a solution it is.

I think you understand just fine.
Definition:
Exposure compensation is a technique for adjusting the exposure indicated by a photographic exposure meter, in consideration of factors that may cause the indicated exposure to result in a less-than-optimal image.


M + Auto ISO lacks that.

I hate it when my Manual mode isn't Automatic...

On a serious note, it would be nice for a working EC, but it certainly doesn't render the Auto ISO feature "useless."
