K20D Auto EV problem

Hey guys,

I have been noticing lately that my K20 has auto EV adjust on Manual only, and I have checked all the settings and it isn't turned on.

Anyone had a similar problem?

What is the option for Auto-EV set to in custom options menu? How do you know it is enabled in manual mode only?

it isnt enabled at all, when in manual mode I can watch it auto correct through the viewer on the bottom.

I've also tried taking the same shot at various speeds and I got the exact same exposure

What do you mean by, "I can watch it auto correct through the viewer on the bottom"?

Posting one or two of the images (with exif intact) that display the problem might be helpful in diagnosing the problem.

Whoah, Auto-EV never did this on mine...

All it does is to change the Aperture value if you are in Av and it cannot compensate with ISO and speed, or change the speed if you are in Tv, etc...

But in manual, no, never changed anything...

If I recall right, all the auto EV does in manual is move the exposure scale one way or another. You must still make the correction because... you are in M.

Auto EV

H i All,
I thought when EV was enabled and applied in manual, the firmware looks at
one of the four flags in custom setting #1(Program Line) and then branched
along that choice, with an ultimate output of apeture, shutter, or sensitivity
adjustment? Then, if auto EV comp is enabled, it would react accordingly.

you guys could be right, I'm going to take a few more test shots today and see if they are different.

It could just be me seeing that bar moving and getting a variable light source (old flash), ill try some nature light shots today and see if theya re any different.

I use manual all the time, the exposure bar changes depending on how much light enters the lens, if the light changes so does the bar. It is to let you know that the exposure is wrong and needs adjustment. It doesn't show the exposure compensation, just change the shutter speed so the small exposure indicator is in the middle.

I figured that, but when I was playing with the exposure one day it wasnt changing on the image which could only mean it was compensating. That or as i mentioned before my flash wasnt giving consistant light

Have we not figured this out yet?

Go outside tomorrow during the day and set the camera to Av mode, f/5.6, ISO 100. Note what settings it chooses for shutter speed.

Switch to manual mode. And choose the same settings. Take a picture. Turn the aperture up to f/16 and don't change anything else. Take a similar picture as the last one.

Do they look the same exposure-wise?
