You try go custom functions, check can set min and max shutter speed range and aperture range?

I know if there's this function, the default is:
- Aperture: min f/1.0, max f/91
- Shutter: min 30s, max 1/8000s

I think 7D should be can bah, it's quite a new model..


if you shoot street in bring day light, you can do ISO200, set min shutter 1/200s, then make use of EC. I think ISO200 with min 1/200s @ f/4 have rooms for play under board daylight

tmr then try, going to zzz liao.

bright daylight, ISO 100 no problem, can hit 1/400s - 1/640s easily with f4.

ok, good night then

Wah lau everybody is confused on the issue of No Exposure Compensation with Auto ISO on Manual Mode. This is a fact. Period.

Work arounds are not considered exposure compensations. Neither is changing shutter speed or aperture because it defeats the initial purpose - which is to compensate for the ISO value.

So what do we do now? Manually change ISO speed to get our desired exposure.

Can? Arguments?

can la, do what i do lor. force the camera to overexposure with base ISO limit. but only applicable under certain(very bright) circumstances. :bsmilie:

Haha so troublesome might as well manually set ISO. Set. Lol...

 

[tecnica]

just to share this pic, done with my mentioned technique...

or use my suggestion lor, set min shutter under C.Fn, go Av mode and manually set a slightly higher ISO than needed (ie, under mid-day use ISO200, min shutter 1/250, use your desired aperture). You still can set the EC you want under Av.

I think this is the best workaround I can think of..

my understanding on AUTO ISO:

In AV mode, we set the aperture and the camera compensates the shutter speed. In short, this is AUTO shutter speed mode.
In TV mode, we set the shutter speed and the camera compensates the aperture. In short, this is AUTO aperture mode.

For Auto ISO mode, I am expecting us to set both the shutter speed and aperture AND the camera compensates the ISO value. Setting the limits of shutter speed, aperture and ISO can be done since 1D Mark III days... nothing new but that is definitely not the same as AUTO ISO.

afaik, auto ISO is not a mode, it is a function under one of the modes.

auto ISO is just like what itself implies, ISO on auto setting, self-adjusting to fit the aperture + shutter speed settings.

hmm, but for shutter speed and aperture limits, i not sure how it links.

Yes bro, 1D4 can do exactly that. Go Manual, set BOTH the shutter and aperture, then press the ISO button, use the "AUTO" option. It will auto compensate the ISO value and the value the system selects will show on your screen/VF. By default, 1D4 will use ISO 50-102400, which is the whole range for 1D4. But I am sure you don't want to shoot over a certain ISO value, that's why you can control the usable ISO range under C.Fn Exposure.

1D4 does have the Auto ISO you are talking about - set BOTH shutter speed and aperture and system automatically compensates the ISO, just like 5D3 can.

iam surprise that the 1D3 do not have Auto ISO.
my previous camera 1000D and 7D has it.
i always thought it should be a very basic feature.

 

[yrh0413]

:bsmilie: :bsmilie: tried on my 1D3, turn the dial all the way to the left and then again to the right...

blardy hell no "A" sign at all! :bsmilie: :bsmilie: you are right guys, 1D3 does not have auto ISO but 1D4 has it. My apologies.

Actually I never ever set my ISO to Auto. I worry that the camera may end up "choosing" a much higher ISO than is needed....I still prefer to set the ISO myself and work around the shutter speed and aperture. I never have a problem or ever wished for Auto ISO before. That's why as I read in this thread, I am quite surprised at why so many people are raving at this function :think: Maybe I too outdated :embrass:

 

[dodgethis]

If you're so worried about the maximum ISO setting being too high, just set a maximum limit duh.

last time I also don't like auto ISO. But I have come to realise that it is quite useful.

Please explain the meaning of this word.

:bsmilie: did some read-up. Canon first introduced auto ISO on 40D. Heck I used the 40D for 2 years before I trade it for a 1D3 and I was never aware that there is an "A" wording before the lowest ISO!

Best of all I only got to know this auto ISO feature was available on my ex-40D today, 5 years later! Now who is being outdated? :bsmilie: :bsmilie:

Auto ISO is a very useful feature. It lets you concentrate on shooting with your chosen shutter speed and aperture without the need to worry about changing lights. If you worry about high ISO, restrict the range of ISO you can accept via C.Fn - Exposure settings

Haha, me too, I sold my 7D and now then I know it got auto ISO...:bsmilie: Tell you to read manual liao....see la, miss good stuff already ;p
