Default What does the EOS 5D MII "Full Auto Mode" really do?

I have a controlled environment and when I take a picture on "Full Auto" (green rectangle) using my Canon EOS 5D Mark II it looks crisp, sharp and really nice.

Now, when I take the exact same aperture, shutter speed, ISO and PictureStyle (Standard) but I do it in "Manual" mode (M) the resulting picture looks darker, low contrast and fuzzy.

What is Full Auto mode doing behind the scenes and how can I get the same results in Manual mode?

ISO: 100
PictureStyle: Stadard
Focus Mode: Auto
Lens: 50mm 1:1.4
Body: Canon EOS 5D Mark II (latest firmware)

Sure! Is Jpeg OK or do I need to post CR2?

Just a guess, but I would say the camera is probably increasing contrast, sharpening, and color saturation when using that mode. Try increasing these settings when you use manual, and see if you don't get the same results.

I think brian has hit it. To find out, look at the EXIF data for the two photos (that is what folks here will be looking at if you post them). Likely it will show the sharpening et.al. settings for the full auto.

If that fails, RTFM (Read The Fine manual).
