Out of focus help for Canon 5d mkii

[Txjasper]

I purchased the Canon 5d mkii camera 2nd hand. My photos are extremely soft. I reset factory settings and did an experiment. I set up the camera on a tripod and focused it on typed words taped to the wall. I used Canon's 50mm 1.8 stm lens. I turned auto focus off. Manually focused the camera using liveview until it was in focus at 10x zoomed, then used the 10 sec delayed shutter to take the photo. The photo is still extremely soft.  Its not soft in liveview 10xs zoomed but the photo is. I also set the micro adjustments for the lens when in auto focus until is was extremely sharp, but photos are still soft.

I did the exact same experient with my Canon 60d with the exact same lens and same settings and the photo was cryatal clear on the 60d. I realize it's full frame vs cropped but the 5d mkii is suppose to have more pixels and be sharper than the 60d.

Please help!

What settings are you using can you please provide a picture with EXIF Data intact.

Settings were reset to factory settings. Pictures were taken using 1/100 F1.8, ISO, 100, AWB, (picture style 5,1,1,0) shooting in AV mode. Evaluative metering. 

In liveview edges were clean and in focus at 10x zoomed but picture was soft at 10x zoomed. It does this with other lenses too. 

My 60d photos are extremely sharp with exact same settings and lenses.

My 5d mkii was dropped at some point by previous owner because there is an impact at the bottom case by battery door. Don't know it that has anything to do with it not being in focus. 

I can upload photos in a little while.

You do realize F/1.8 has paper thin depth of field on Full Frame compared to APS-C. Try stopping down to F/2. No lens is sharp wide open. 

The picture below was taken at F/1.8 on an APS-C camera 

Gear: EOS 40D, EF 50mm F/1.8 STM Settings: Tv 1/1000th sec, AV F/1.8, ISO 100

This picture was taken at F/2 on a Full Frame camera

I understand that. Did that too. Same results... it does it at f4 and f8. 60d is sharper at the same fstop. I took same photos with the same variable canon 28-135mm lens and set it at 35mm on 60d croped sensor at f8 and 50mm on 5d mkii at f8. 60d produces sharper images every time.

What's frustrating is the image is clear through liveview zoomed in at 10xs. I turned autofocus off so it would not adjust and time delayed shutter to reduce shake while on tripod but regardless of fstop image is't as sharp as on liveview and my 60d outperfoms my 5d mkii every time.

Also, I was focusing on paper...so the depth of field I was using was paper thin.

"My 5d mkii was dropped at some point by previous owner because there is an impact at the bottom case by battery door.

If you didn't realize a crop sensor camera doesn't see the edges of a Full Frame lens. It only sees the center part of the lens. On the 5D Mark II the image sensor sees the entire image circle that a Full Frame lens projects. Also the Angle of View of the 50mm is 80mm on 60D do to the image sensor being smaller than 35mm film. Again can you please post the pictures in the forum with meta data. We can't see what you're talking about without pictures. The pictures I posted were with the EF 50mm F/1.8 STM lens on the EOS 5D Mark IV & EOS 40D. Why are you shooting wide open anyway? Pictures are usually soft wide open.
