well I'll be, they fixed ETTL on the 10

I leave the forum for 16 hours and miss all this news. I guess this will make a few more people happy. I'm kind of shocked that Canon seems to have addressed almost everyone's complaints. About the only thing they left out was the 1.6x crop, but of course they did that to get a DSLR out there that can comes in under the competition in price. I'm sure they've got more up their sleeves.

Here's the text from the web site:

To obtain more stable flash exposures, the EOS 10D's algorithm for calculating the main flash output is based on the algorithm used by the EOS-1V and EOS-1D/1Ds. Since a wide area of the entire image is metered for flash, the flash expsosure remains stable even if the framing is slightly changed. Meter readings from highly reflective surfaces are ignored or the weighting is reduced so that it will not adversely affect the exposure of the subject.

Never was a problem for me, but I'm sure it will make some people happy.

It looks like a nice change to me. I found Canon's presentation of the new camera very well done. If you haven't seen it yet, take a look.
 
...got excited, but did not want to jump to any conclusions. The demo flash also mentioned of some kind of WB sensor reading -- now this one still got me scratching my head.

So what if you are photographing a bunch of people in camoflage? Or a gorilla? I'm talking about sponges for light...the problem is metering for reflected light. It sounds like it might be better, but it still won't work as well as a 283.

I never did find that, but I really doubt that'd ever be a WB sensor, as it'd get blocked a lot. Plus, making something both a light and a WB sensor might be tricky. Not a huge loss IMO, as several cameras without WB sensors seem to do a better job than the 1D/1Ds in the WB front anyway.

But your 283 meters for reflected light as well - unless you are using it in manual with an incedent flash meter.

However, go to the official 10D site at:

http://web.canon.jp/Imaging/EOS10D/

skip the intro, click on shooting performance, then click on metering.

Yea!! The flash exposures on the D30 were very inconsistent (based on my use). Now if it will just autofocus better!

Well, the last camera to be reviewed is one:

http://www.dpreview.com/reviews/hp850/page11.asp

Compare that to the sensor assisted 1Ds performance here:

http://www.dpreview.com/reviews/canoneos1ds/page15.asp

Myself, I don't much care about this feature. I occasionally WB adjust indoor shots perfectly with the RAW conversion dropper feature, but then I find that I like the mood of the tungsten lighting for instance more than a "correct" shot.

A thyristor flash works by measuring the distance from the flash to the subject. It shoots, waits for the light to bounce back, then shuts off. The reflective nature of the subject is not considered, only its distance from the flash. In my opinion, that's the way a flash should work.

Sorry, but that is not correct. It works by measuring the light reflected from the subject. Low cost electronics is not fast enought to measure the distance using the speed of light.

Try it with black subjects or white subjects, and you will see.

While the HP WB review certainly says it all--for those with HPs.

The issue here--and it's good news for Canon people--is that in comparison to the D60 , the 1Ds and the new D10 are way better both in accuracy of ETTL flash exposure and auto WB.

After all, the only real problem area noted with Canon Auto WB was with tungsten lighting--and there's a pretty good preset for that.

If you've got an HP--great. It has the best auto WB. If you're stepping up from a D60 to the D10, it's nice to know your flash and WB are going to be significantly better.

Thyristor flash measures light returned from the scene using a photo cell and the thyristor is the semiconductor device which turns off the flow of current from the capacitor to the flashtube.
