Ok here it is you guys. I found out that it's actually exactly in focus at +10 and NOT +10 & +5, I must've looked it wrong yesterday because I did 8x zoom in my camera to calibrate the DA* 50-135
Here is 100 percent up-close of the photos. Cropped in photoshop to show up-close of where I focused, and unedited in any other way. I focused on the red On/Off button of the vacuum cleaner. All photos were taken at f2.8 and 135mm on the K-5.
This first picture was taken with +10 individual lens correction along with another +5 in all lens correction.
This second picture was taken with +10 individual lens correction only.
