I got my E620 in last week and had been playing around with it here and there. I kept noticing that the lcd looked "noisy". Tonight I took a couple images with the 620 and a couple similar images with the 510 to compare. The 620 looks darker and grainy. Do I have a bad camera or are there settings within the camera that could cause this? The only other difference is different CF cards. Could I have a card going bad? Please advise.



 
You're at least a stop underexposed. All cameras will be noisy in that situation.

Thanks for the Dadaist pep talk. I feel much more abstract now.
 
It was obvious to me, but maybe not you guys. The first image is with the 510. Second image taken with 620.
 
The image taken with the 510 is slightly underexposed as well. Yet it looks much better. I took some shots before this...in low light, and the blacks were extremely "grainy". I've taken a lot of low light images with the 510 and never had this problem.
 
Are you sure the settings are the same? Looking at both files in the Olympus Master software under the Basic Info Tab, it shows the white balance temperatures are different and gradation, contrast, saturation and sharpness are all different and that the flash fired at a different level.

But, I don't know whether that is just a glitch in the Oly program and it is misreading the data or what he deal is.

Lots to guess at - more information is required.

I made sure the settings were exactly the same on these. The 620 is extremely underexposed compared to the 510. Yes the 2nd image is almost completely black. It was taken with the exact same settings as the Xbox/Wii picture taken with the 510.

Wow...I have no idea why...but that looks bad. I just have the E-500 and E-510.

What are the settings for each of those (even if they were the same)...the ISO...f-stop, shutter speed etc., so maybe someone here can help you?
 
The second one is closer to reality - the window frame and fabric are a good indicator.

For testing purposes, I had WB set to Auto. My concern is why the 620 is so underexposed where the 510 is only slighty underxposed. Why does the 620 images look grainier? The settings are the exact same on both cameras.
 
Well it seems to me that the 620 is faulty, I checked your exif-info and really the settings seem to be the same. Just try one more thing; shoot outdoors in good light without flash + same settings in both cameras. Lets see what the results are..

The reason for the "noisyness" is just the underexposing and white balance differences. The auto-WB can produce varying results in different cameras (the 620 has external WB sensor and all) AND correcting the warm indoors lightning always pushes the blue channel noise - alot. Putting both cameras to same kelvin WB should yield similar results. If not, there's still some difference in noise handling and gradiation (contrast).
 
Please take some comparisons in daylight too - at the moment all your shots are with flash, which can be affected by its own settings, battery charge and so on.
 
Pertinent EXIF information (both images):

Manual Exposure Mode
SPOT METERING
ISO 200
f/3.2
1/30
147 mm
FLASH = FLASH FIRED, COMPULSORY FLASH MODE

So - did you have the flash in TTL (lightening bolt) or manual (lightening bolt + Full/ 1/2 / 1/4 / 1/8, etc)

I suspect that we finally have an Oly camera that does real TTL spot metering with flash. The flash output was clipped when the center spot was exposed - resutling in a darker frame for the 620.

Again (because I could never prove it) I've suspect the E-1/3, E-500, and E-410 (all which I've had experience with) have a pseudo-ESP metering for TTL, which commonly results in overexposure of the foreground (as the flash tries to light the whole scene). The same is probably true on your E-510.

So try another shot with TTL and ESP metering with the 620 and let us know!

Excellent suggestion Adam, i learned a bit there, and that could indeed explain things...

Switch back to ESP metering and you'll see that your problems magically disapperar. I really doubt it's the camera problem.

That is what I would try too.

I would also try setting the camera to ESP and not Spot metering (with the flash) but, for what it's worth, I tried several different subjects with my 620 in both Spot and ESP metering with the flash and there was no discernible difference in exposures.

With that second set of images he posted, I am wondering if his in camera flash is working properly. Without being able to troubleshoot the camera in hand, I can't say for sure but I have a hard time imagining a photo where, with the same settings, the 510 would expose ok and the 620 would give a photo so underexposed that it is all black.
