Question about Sigma EF-500 DG for TTL Flash

Open Question

Under exposing, especially when bouncing & diffusing

Bought this new for my brother's EOS 400D, was mostly intermittently underexposing. I gave him my 420EX which works flawlessly, and I have now pinned down the problem on my 20D as follows.
1. Straight flash works ok, flash zooms ok.
2. When bouncing of roof, walls, ALWAYS underexposing (compared to my weaker 420EX), virtually useless results.
3. When using the built in -28mm diffuser, massive underexposure.
Dealer initially said he was willing to exchange it, now "to long time has passed".

SOURCE: Problem with underexposed pictures

I've got the same problem with my new ef 500 dg super and my ef 530 dg super. It occurs on all nikon camera's I could get.
D70, D80 and Fuji S5 Pro. I don't have this problem with an old (4 years) sigma ef 500 dg super.
I will try to contact Sigma for this problem.

Yes, at the local Home Depot or Lowes they should have them. They're usually anywhere from 3 to 8 dollars unless they're specialty (stained glass or something like that) ones.

SOURCE: no air coming from air diffuser assembly in fridge

through other postings on your web site I was able to determine that the return air flow vents for the refrigerator (diffuser air) was blocked due to frost. I defrosted the unit and it is working fine now.

Can i use a Cullmann C28 flash with Canon Eos 400d?


Doubtful. I tried similar with a different brand of flash designed for a 35mm. It worked for about 20 shots then the diodes fried. I've since bought a used Speedlight for my 400D and it works great.

Be aware that the built in flash does not pop up automatically in all picture modes. Try it when in the different modes (on the mode dial) and see what I mean. Does it popo up when manually opened ?, (small button on front left hand side of the viewing pentaprism/flash housing.)

Turning on infared on my Canon EOS 400d DSLR


To the right of the LCD there are some small buttons. Right underneath the AV button, there's one. Press it, and you get three choices. The right most choice is self timer and wireless. Choose that option. The remote needs to be pointed towards the eye on the camera. It's on the front, on the "motor grip". And if you leave it on that setting too long, it "falls asleep", and you have to wake it up again before it'll fire remotely.

EOS 400D Digital Camera Software


Hi
If you bought your camera (400D) new it would have come with RAW conversion software on a disk. You can start by installing this. To get the photos off the camera you should be able to plug it in vis the USB cable that came with it. The better way would be to buy a card reader. This is a lot quicker, save on battery wear and tear, or save you plugging in the power.

Alternative software would be to buy Adobe Photoshop Elements for the RAW processing. This is a good start for most people.

Canon EOS 400D LCD screen problem


There is no live preview mode on this camera. I am not sure if that is what you are referring to, but you can only use LCD for review and menu, not as a viewfinder.

The new Rebel XSi is the only one in the rebel series with this new feature.

Hope this helps!
