Auto ISO help

[sk66]

I can put the camera into Tv mode and set the shutter to X say 500 I can go into Cfn settings and limit the aperture to Y ...such as f2.8 with that workaround i ahve the set shutter and set fstop and can use EC with auto ISO.. its the same as manual .. I have the setup saved and it shows up as a as a MODE so i can easy get to it... one flick of the dial and all the settings are there ready to use so i dont have to change every time..

So you have a fixed aperture you have to go into the menus to change?

Less than ideal but workable for many subjects/situations...

I'm a wedding tog and I use Auto ISO unless I'm using flash (as it defaults on Canon's to ISO 400 when flash is on and you can't change it which is annoying).

It just means I can concentrate on composition etc, and is basically one less thing to think about. I shoot a 5D MK III & 6D though so it doesn't matter if I'm at ISO 5000.

I also use AV with a min shutter speed, so again one less thing to concentrate on.

I used to use manual everything but now I can happily flick between Auto ISO / AV and full manual. The tools are there to help and if you use them right you can get a lot of benefit from them IMO.

However... No way would I use Auto ISO on a 7D... I know what that camera's like with ISO's from my own use and I'd always want to be in full control of it. It's fine when using a camera with high ISO capabilities, but the 7D IMO doesn't fit in to that category

eh? why do you think full manual exposure control is right for every situation? because believe me it isnt..

and what makes you think anyone in this thread doesnt know how to use all modes?

What he said - it's a bewildering response I won't go into all the reasons why

The problem with auto ISO and EC is that the camera's processor is constantly trying to correct the compensation you dial in, if you try to do it manually its still doing the same thing and altering the ISO to give you a balanced exposure.

And what's wrong with that? As noted, the meter is always "right", and if you understand metering/metering modes you'll know when/why "right" isn't what you want... That's what EC is for.

If the lighting changes (and I would say if the subject changes) then the exposure has to change. You can do it manually, or let the camera do it for you....the camera can do it much more quickly and accurately than you can (it's not limited to 1/2 or 1/3 stops). Anytime I have to take a finger/thumb off of a button in order to twist a dial it slows things down. It's even worse if I have to hit/hold a button and then turn a dial...I can't change ISO w/out looking because the little button is in different places on my cameras and I can't reach it with my right hand. And it's worse yet if you have to go into the menus.

I set my cameras to change the settings for me; in the exact same sequence/order of priority as I would change them manually. I can always change the exposure w/ EC (Nikon). And I can always shift the equation around by changing aperture (in A/Av/M) or SS (in S/Tv/M). There's no loss of control.

I think the real issue is not understanding metering/metering mode/metering point or what your camera is doing and why.

Can't you set a limit for the auto ISO on the 7D? Granted, it's not a lot of help if it's only going between 200-800, but it's something. (actually, 2 stops can be a pretty big deal when it comes to SS).

.

No.. its a workaround for the no EC on auto iso and done as above it gives you exact the same as Manual+autoISO+EC which canon 1d series (and?) currently doesnt support..

When i change the MODE dial from av to tv to manual etc.. theres another option for my saved mode which includes the workaround.. so its too easy.. easier than switching to manual and turning auto iso on as its all set
