Actually that is just results. How many judges is the sample size...

5D: In-Camera Meter Calibration? [Archive] - Open Photography Forums Doug Kerr
May 30th, 2006, 03:20 PM
Hi, Amit,
This area is more complicated that one might think.
A short answer is this:
1. The internal meter is generally calibrated consistently with the applicable ISO standrds. That is, the aperture/shutter speed combination it chooses (indicates) is consistent with what one would expect for a meter calibrated under ISO standards.
2. In fact, the sensitivity of the sensor, when set to "ISO 100", would probably be rated in a test under the applicable ISO standard at about ISO 125-135
3. The implication of this is that the camera in metered operation will provide an expsure on the sensor about 0.4 stop "hot" compared to what is contemplated by the ISO standards.
4. The ISO standards, taken together, provide an expsure result that, in effect, allows a 1/2 stop headroom to prevent blowing out of the highlights in the case that the scene being metered has a substantially lower average reflectance than is contemplated in the meter calibration.
From here on this is just my conjecture.
5. I suspect that Canon feels, because of the fact that the Evaluative metering system is smarter than the metering system contemplated by the ISO standard (which is just based on the detemination oif average scene luminace), it does a better job of outguessing the highlights. Therefore the 1/2 stop headroom bulit into the ISO standards isn't needed. So evidently they decided to "burn" it.
6. They could have done this by adopting a hotter "calibration" of the exposure metering system than called for by the ISO stadanrd. But if they did, then a photographer who used an external exposure meter (calibrated in accordance with the ISO standard) would get a different exposure recomendation than for the metering system in the camera. This would have caused a lot of consternation.
7. Therfore, apparently, they decided to burn the headroom by underating the ISO sensitivity of the sensor system.
So to answer your question: The expsure meter in the camera is probably "accurate". But that's not the whole story.
If you want your external expsure meter to recommen an expsure that will give a result consistent with what you get with the in-camera metering, you need to set the ISO sensitivity on teh meter to teh face vaolue set on teh camera - oif you set the camera to ISO 100, set teh externqal meter to ISO 100.
If you want some more information on who this works, you might want to look at my tutorial article, "Exposure Meter Calibration", available here:

But, then, so.. What?
Since Pentax has not won any major award or prize since the MZ-5 in 1995 until the K10D now. So, I bet the K10D can go strong for another twelve years until the next "real thing" comes (in 2019?)! ;-D LOL!
Again nothing but gloom and doom and predictions (as is your style) of disaster and failure. If anything is too dark it's your attitude.
Originally posted by RiceHigh Me too. My 5D is just used as a P&S camera in my hands and I shoot jpegs mostly with it. In contrast, with all my Pentax DSLRs, I shoot in RAW almost 100% of time and have spent tremendous of time in Post Processing these RAW files to yield "great" looking results. I think my Pentax DSLRs must be a more professional camera for each of them as I use them much more professionally!
You would have been better off w/ a P&S. Then you wouldn't even have to "bother" w/ the drudgery of switching a lens ever. And PP is usually NOT as time consuming as you make it out to be. Only depends on how you approach it.
Most Pentax shots just have compressed contrast. Takes a second to do a contrast boost and if needed (and admittidly most of the time at defaults due to the metering adhereing to the ANSI standard and NOT cheating on the ISO ala Canon
) an exposure boost. And to use a worn out analogy, Ansel Adams probably spent much more time "tweaking" his RAW files (film) then just taking the shot. MAYBE he wouldn't have to in the digital age BUT it is part of the mystique.
Now since you seem as busy as me, this "time" seems to be plenty available.
The sad thing is your pride will not allow you to EVER see your error in thinking.....
