Question about Canon EOS 30D / EF-S 17-85mm IS Digital Camera

Open Question

Some EOS CANON camera issues with exposure, with and without the 580EX Speedlite flash. The shots come out either way over exposed, or underexposed, even in the manual setting. Are there software updates that can be downloaded that may correct this?

    I have not heard of any glitches in the software that cause intermittent exposure problems. It sound as if there is a problem with the settings or a mechanical problem. Can you tell me if it is doing it in al lthe modes, besides manual?

Buy the 550EX, it's cheaper

Master /or Slave = 550
Slave = other

SOURCE: Underexposed image on Auto mode

You can change the ISO setting also to Auto. If you have the advanced guide (see pp 80, 107).
Press the ISO button it will switch from various ISO setting to AUTO.

Do remember in Bright light , a lower ISO number like 80 will give you very fine images, while as the light level goes down, the ISO number will change to a higher number and the image will become more grainer.
I hope I could answer to your query.
Please do rate. Thanks

SOURCE: Photos are super over exposed when using 430

if overexposed, what yuou can try and do is make the shutter speed faster (so less light reaches the sensor) or reduce to the ISO setting to 200 or lower as needed. Both these will help with overexposed images. I wouldn't recommend consulting the manual because there are so many variables... The manual doesn't know exactly how much light there will be in very shot you take, and that is the crux of photography, working out what settings work best with the light available for each shot.

Hope that helps!

Canon Speedlite 580ex ii - won't work with camera


Caroline, you should try to set the camera on "M" and the flash in 2nd curtain flash sync.

Or set flash in ATG wireless IR ETTL Slave modes and pop-up the flash on Canon EOS-70D.

I have recently shot some pictures with my canon 580 EX flash. pictures seemed to be a bit underexposed. My camera is a 50D pictures shot at ISO 200. The lens was a canon 17-40 F4 L. Is is possible that...


It all depends on the environment you're shooting in. When shooting a wedding reception for instance inside in the evening I will generally use ISO 800 and I quite often use FE Lock which is very handy. FE Lock will pre-flash the speedlite and meter the result based on the center focus point in your viewfinder (it doesn't matter if you have set another focus point it will always meter to the center one so make sure that is over your subject when you use it). To use FE Lock press the button near your thumb that has the * symbol with the center focus point over the subject. You can then re-frame the shot if required and take the picture. The camera will take the picture based on that flash setting and you should find that the shot is better exposed.

Recently my canon speedlight 580 EX II TTL has been acting up...especially in low light situations. About on in 30 shots actually has enough light in them...the rest of the time the shots are...


that the camera/flash set-up I use ... there are many variables - iso/metering setting/shutter settings/flash settings .
If it's a flash function problem, try this to isolate it - first, with the diffuser/reflectors tucked into the flash head, and the head straight up, with the flash set in master mode, turn it on and look on the back screen. push the mode button til you see the ETTL in the upper left of the screen .. then press the set button in the center of the dial and the nuber in the center of the display should flash (+0) while the light is flashing, rotate the dial to change the setting (i usually under power by 1/3 stop. Play with the exposures a few times to get the feel for what the EV shifts do to your exposure. generally speaking, for interior low-light, i prefer to bounce off the ceiling (if low ceilinged), if there's too much direct it will give you an uneven and predominantly underexposed image.
if you prees the mode button you will come to the same options for adjusting the output in manual mode, but it will not work with the autoexposure in the camera.
Try playing with the ETTL settings
I think the problem may be that you have somehow altered the power output setting on the 580.

Remote Firing of Flash Units


The EOS 40D does not have a transmitter built in. The remote flash units must be set to "Slave" and the on-camera external flash unit (eg Speedlite 580EX) or transmitter (ST-E2) set to "Master". Note that the Speedlite 430EX doesn't have the function to act as Master and you need a minimum or the 580EX or a ST-E2 speedlite transmitter (or similar) as Master/s.

ALL Canon digital EOS cameras will work with E-TTL only. Solution: you need EX flash for full auto.
