I shot some pics at a baseball game with my markII and the red on their uniforms has vertical lines running through them mostly at the edges. Also I have had trouble getting bright reds to not be blown out. I shoot jpg, sharpening at 3 and adobe color matrix. Sorry I don’t have any way to post a sample. I am just wondering if any of you have trouble with red, and if so what do you do about it?

post a pic. vertical lines sounds like a real issue. the red color issue may be a problem for some who need accurate color reproduction, but vertical lines is a whole nother ball game. You may have a serious issue that requires repair but you'd have to post some pics for anyone to know.

Looks very similar to what happens to DV video due to it's 4:1:1 sampling. Reds don't get many samples so edges go jaggy.

Some sugguestions:
Looks like JPEG artifacts, maybe the compression is set too high. Do you see the same vertical lines in RAW file?
Your REDs looks OK in my PS, for web posting, you need to change the color profile to sRGB. Otherwise, your picture will look dull.
If the REDs look bad on your monitor, make sure you set your monitor with the right temperature (6500K) and have correct ICC profiles for it.
The REDs can be blown out on the camera very easily, that why you have the R-G-B historgram on the Mk2.

Hard to tell what is causing it from the one sample. Try this test. Next time out shoot RAW + JPEG. Then when you see this again in the JPEG you can go back to the RAW and see if this is an artifact of the capture (the sensor) or of the in camera processing parameters. I'm going to guess it has something to do with the compression or sharpeness artifacting because it always runs along high contrast edges.
Good idea Jay. I will give it a try.
Has anyone tested to see how much quality differnce thier is at different compression values? I have been using the default 8, but I notice that the file size goes up dramaticaly with lager numbers.

you wouldn't wonder what it is... the above cameras do it too. Red edges go blocky/stripy very easily. It often looks like 2-lines-wide blocks (vertical) and sometimes stripes like yours. They're NOT jpeg compression, or bad/strong sharpening...
Look at my 10D:
Bad luck, Gene: looks like it doesn't appreciate the proximity of blue!! look at that "LUBRIFIANTS" flag...! the mkII's CMOS sensor doesn't seem too far from the prosumers, design-wise.

What resolution are these taken? Full 8mp or one of the reduced sizes?
I can see the blown reds but the image as a whole is a bit over exposed in my opinion.
Also, since you took the image in Adobe RGB, how are you viewing it? Posting the aRGB image to view on a web browser is not giving the true colors.
