I was not sure whether to post this here, or the dpreview the 5D, or 7D forums.  But since it is microstock related....

I have been doing microstock for 2 years now.  First with a 50D, then a 7D, and now a 5DMKII.

Prior to the 5DMII my percentage rate of accepted images is about 30-100% depending on the site.

Well.... I got the 5DMII.  And I love the quality of the images and the ISO performance.  The AF system IMO is not as good as the 7D.

BUT....my acceptance rate for the past few weeks since I started using the camera has been about 0-10%.

I don't know why the drop.  It could be that the reviewers have changed over the holidays.  Or it has been rainy or cloudy the last few weeks so making open the aperture more and use higher ISO's.

The most likely candidate is a loss of DOF compared to the way I used to shoot?

Today I took shots on a monopod at higher apertures.....we will see what happens.

Kinda hard to say without seeing full size images and rejection reasons Could be camera settings, workflow, lenses, or a dozen other things. 

I have a 5DMII and for the past year have been in the 90%+ range at Istock.

My first guess would be you're shooting JPEG. IMO the 5DMII JPEGs are a bit soft. RAW detail is pretty amazing.

As has been said, you need to share your rejection reasons. Since I got the 5D2, my rejections for artifacting etc have gone down, compensated by 'poor lighting' rejections shooting up.

It's strictly coincidence. I'm getting more rejections since I started using a new espresso maker.

Could it be that the lens you have isn't good enough for the higher resolution?

Its not the camera!  I work with the D3X and the MII ( both systems)  the higher res, the more demanding and the more unforgiving. These cams demand best optics and thats just for starters.
Always raw, no sharpening and no noise-red, adobe-space and work in neutral setting,  this is in-camera you understand.

Fewer artifacts in tea no doubt.

But seriously.... most of the rejections have been because of OOF or focus not on best area.    I think that the combination of the shallower dof associated with a FF camera combined with hand held shots in a darker winter environment .... a AF system that is not as good as the 7D has led to my rejections.

Strange: the advantage for me personally is the the 5D2 is far better in lower light conditions with higher ISO. Do you have IS lenses? Is it out of focus or lens shake?
May be a problem with the camera or lens?
What sort of subject are you shooting? Unless fast moving, e.g. flying birds or sport, the AF difference shouldn't be obvious. (I was recommended the 7D for actions shots, and was thinking about replacing my 40D with one, until I read that the noise at 400 is pretty grim.)
