Canon Speedlite 580EX II TTL Flash - Page 2 Questions & Answers
I mounted the Canon 580EX II to my Canon 5D Mark
Yes. If you were able to set a faster shutter speed, then you would not expose the entire frame and would have the shadow of either the first or second shutter curtain (or both) partially masking the frame.
At higher speeds, the shutter is never fully exposed: before the first shutter curtain has finished travelling across the frame, the second one has stated it's journey. All SLR's have this issue and on some older models you could only use a maximum 1/60th of a second.
In practice though, in dark conditions the "slow" shutter speed does not affect exposure as the true exposure will be determined by how much light the flash puts out, and it puts this light out in as little as 50 microseconds (50 millionths of a second) for a modern electronic flash bulb.
Faster shutter speeds can be used successfully, but only with flashes which operate in high speed mode. What they do is to make the flash burst seem longer by rapidly firing the flash bulb many times. This trick can ensure that there is sufficient light to expose the frame at the highest shutter speeds. Shutters which operate at, say, 1/4000 may seem fast, but compared to the speed at which a single electronic flash burst operates, it's an eternity.
Recently my canon speedlight 580 EX II TTL has
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.
I have the 580 ex2 mounted to a eos 5d mark 2.
The shadow is caused by the lens and lens shade if you use one. If you are shooting "up close and zoomed in" regularly, get yourself a ring flash. It fits around the end of the lens = no shadow.
Other ideas::
Light it from below/behind or from the side. Put your 580 on wireless, and place it along side the subject. I recommend a reflector on the side opposite the flash.
Use a piece of white paper as your reflector.

You can try to use a super bonding agent with filler such as 'Q-BOND superglue kit' which is normally sold in many auto shops and can also be found on Ebay: it is not an ordinary superglue and is commonly used to repair difficult plastic and metal parts.
Q-bond also has a very long shelf life even after opening the container as it is almost pure superglue!
Hope it helps.
Reverting to ttl - master flash not firing
Hi Kate,
What camera that you are having problem with those flashes?
Will switching the two have the same problems.
Make sure it is fully pushed forward into hotshoe & locked:-)
Try shooting second current, this will save you the repair costs.
Your exposure compensation was set to zero, but was your flash compensation set at zero?

I purchased a new Canon 580 EX II in July and have
Trust me I have this flash and I LOVE IT, I wouldn't trade it for the world.
Sounds like you have a short somewhere, where did you buy it? Remember Canon gives you a full one year warranty BUT it must be the Canon USA and not Japan model....THAT is where it hurts! Read the fine print, it may be cheaper but that does not mean it will be better.
Even if you have lost your receipt Canon will have you on file, because you registered your Canon product, right??
If you need it fixed, I have the guy for you, but I am located in the San Francisco Bay Area. I am sure you can call him on the phone and he can see if it's worth you having it shipped.
But FIRST CALL CANON they are awesome, and want you happy! And only buy B&H Photo.com they are amazing and NO SALES TAX for online
Keep us posted!

I have a canon rebel camera,i also have a canon
I had the same problem with a 400d and 580exmkii however the problem seemed to disapear when i used a white plastic flash defuiser over the unit.(available from stores or ebay) also note this model produces a lot of underexposure and some brand of batt heat up very quickly. For indoor set to camera to manual and flash to ettl. Best of luck.
I have a Canon Speedlite
Perhaps the unit is set to master/slave mode. Look into that.
hint: Press and hold on the zoom button to get into the master/slave menu
Canon 12x36 is ii stabilization is not working properly. Stabilization
tends to want to stray.
Hello, I think dust, smudges, or fingerprints on the lenses can affect image quality and stabilization performance. Use a soft, lint-free cloth or lens cleaning solution to gently clean the lenses of your binoculars. Make sure not to apply excessive pressure or use abrasive materials that could scratch the lens surface. Moreover, when using image-stabilized binoculars, it's important to hold them steadily and avoid sudden movements. Rest your elbows on a stable surface or use a tripod if possible to minimize hand tremors. Ensure that you're using proper stabilization techniques to maximize the effectiveness of the stabilization feature.
