Hi folks,

Probably being a bit of a fool here but........

Just bought a 40D and reading the manual (if I'm reading correctly) in manual mode I line the the white marker with the power on switch and can then adjust shutter speed from the main dial, fine, but turning the quick control dial does nothing, should this not be changing aperture?
 
the start button has an extra mark (line) on it.. it has to be turned to this for the aperture wheel to work......it prevents it gettting moved when you dont want it to :thumbs:

if the mark on the power switch is pointing to the word ON... the aperture cannot be changed.
 
Yep, tried it in both on positions, sure it must be a schoolboy error but I just can't what I'm doing wrong.
 
With your camera turned off, turning 1 click on will allow you to adjust shutter speed but not aperture, turning 2 clicks on will let you adjust both.

Trying that (in manual mode) but moving two clicks only allows me to adjust shutter speed (top dial), turning the wheel on the back of the camera does nothing.

Anything that would prevent me from changing aperture, a setting in a menu perhaps?

:thinking:
 
He seems to say he has tried BOTH the on settings... ie, ON and white marker above the ON mark. :shrug:
 
Mine works the same as Micheal says
 
very strange! :suspect:
 
I presume if the camera been just bought then it might be a problem with the wheel itself ....
 
Try a reset to default settings if you haven't changed anything?
 
I seem to remember mine didn't either, but worked with the "on" button set to on, on the first click not the second click, then holding the -zoom button and turning the top wheel, it adjusted the shutter speed and the +zoom to adjust aperture, on manual mode.

Hope this helps:thumbs:
 
Just thinking on me feet, perhaps it firmware?

I have version 1.0.8.
 
With the power switch to _

In manual mode, one wheel is aperture and the other is shutter.

In either Tv or Av mode, the front wheel adjusts either aperture or shutter and the rear is used for exposure compensation.

With the power switch to just on, the rear wheel doesn't do anything apart from review and alter settings.
 
I had the 1.0.8 firmware as well. My guess is that you've customised the buttons.

I remember I wanted the large thumb wheel to select the AF points and not aperture...

Suggest putting the camera onto the first click, then hold down each button whilst moving the top wheel, then you should get a result...

Cheers Mark,

Tried that but no joy

:help:
 
In manual mode, the wheel on the front adjusts shutter speed, and the thumbwheel adjusts aperture.

As youve changed and checked your settings, I would try checking the connection on your lens.
Does the aperture adjust in AV mode?

Also, try taking your batteries out for a few minutes too.
 
Does the quick dial work for flicking through reviewing photos taken, I know someone who bought a 40D and found the quickdial wheel did not work at all.

Connections look fine, tried three different lenses, same result.

aperture changes fine in AV mode (using front wheel)

Battery left out over night, same result.

and yes the thumbwheel works fine reviewing pictures.

Many thanks to everyone who has taken the time to suggest something, I really appreciate it.

As its less than a week old, I will drop in to Jessops today and see what they say.
 
sounds faulty to me. id take it back asap
 
Well, maybe not as thick as I thought.

Back to Jessops today,

"yea, thats they way they are"

Err.... no. at this point my heckles were up and I was just about to ask for my money back.

To be fair they replaced the body with a brand new one, but they did not swap boxes which was a bit strange.

Got them to mark the receipt in case there is any more issues.

New one seems fine so far, thanks again to all who helped, really helps when you can go in sure of how it is and how it should actually be.
 
Glad its sorted. Must have been faulty as we all ran out of ideas...

You can customise what each button does, just to let you know, though I rather think after this, you'll stick with the default setting:lol:

To be fair, you can only customise the SET button in the centre at the back and swap the functions of the top 2 buttons. None of this has any bearing on his problem though..so Hyster, dont use default settings.. customise it your own way and dont let that problem you had take the icing off your cake... you have a superb camera, enjoy it!! :thumbs: :D
 
Thanks Janice...how comes the plus and minus zoom buttons on my 40D adjusted the shutter and aperture then? I'm baffled:thinking:

Waiting for a replacement 40D after it plus all other camera gear was nicked from a nature reserve :'(

plus and minus zoom buttons? oh.. you mean the ones that play back the images and zoom them in and out on the rear lcd? Those change your aperture when in photo taking mode?? I had no idea!!! :D
The only things that change MY aperture/shutter speed are the wheels on the front and back!
 
Yep, I used to hold either button down and moved the small wheel near the shutter button whilst in M mode. Makes me think that they can be customised, but as I say, I don't currently have a 40D to check....

Can't remember how I did it, or whether the change coincided with a firmware upgrade..
 
Not doing that for me :( perhaps MINE'S broken too!! :lol:

it makes no difference if I press any of those buttons and scroll the front wheel, the shutter speed alone moves.... with or without pressing the buttons.

In the custom functions there is the opportunity to change the function of the middle SET button (quality.. etc etc) the af-on and the * button can have their normal functions switched as some find it easier like that.

There is a long custom menu for the AF button on the LENS (which isnt to do with the camera BODY) and lastly there is C-Funct for what your shutter button and AF-button do... ie. metering or starting AF etc.

I REALLY want someone to come on here and tell me either I am not going mad.. but more importantly that my camera hasnt broken!! :eek: :lol:
 
WELL BU**ER ME!!!! I turned off using the right hand button for changing the autofocus point.....and it suddenly enabled me to change aperture by pressing that button!!

YIPPEE!!! Thanks Markta, I wont use it like that, but Im glad Im not mad and my 40d is functioning properly!! :thumbs:
 
Hey I know but yours does seem to be working correctly, according to the 40D manual which I still have:thumbs:

EDIT: sorry I posted this without refreshing the page; been out for about 30 mins..

Ah well, neither of us are going mad then! Reassuring that!:lol:

Well that was jolly nice of them to leave you that.... lets hope they cant work out how to use the 40d without it ............ like us!! :D
 
It actuallly is to do with how you have set your camera to change the focus points. If you have set it so you use the rear wheel direct, CF III - 2, then you cannot use that wheel for changing aperture and have to do it the way you said.

Its horses for courses... and what you get used to. :thumbs:

Aha! And the mystery is solved!
 
Fabulous,thanks for clearing that up Janice! That must be the reason why I changed it; I prefer to use the large thumbwheel for rapidly changing AF points.
 
I dont think i have ever changed my focus point in nearly a year!! just use centre.
