Thank you for response.
I will certainly redo my calibration based on your suggestion.
Much appreciated.

I wonder if there can still be problems with that in sensor AF.

If the OVF AF is not in focus, that is all you need to know that something is off. Unless you are suggesting the use of the Live View image to judge the sharpness of the OVF image. Perhaps some might find that helpful. I suspect that most know what sharp focus looks like.

Put camera on tripod - focus on contrasty subject in good light using live view - then half-press the shutter button (or BBF). If the focus shifts, the viewfinder AF is not optimal.

DreDaze happy with myself for not saying anything stupid  More info | Feb 25, 2020 21:04 | #1565 pknight wrote in post #19016122 You are correct that if the AF through the OVF is different than the AF in Live View, something is off, but what does the Live View add to the process of calibrating the OVF AF?

I suspect that most know what sharp focus looks like. i feel like something could not be in perfect focus and still appear sharp...with live view you know what the optimal sharpness would be Andre or Dre

It is a bit puzzling why the first is a bit soft. You had a great subject to focus on. Maybe try again when the light is brighter, and with a higher shutter speed.

Looks like the light and the moisture in the air were bouncing off of each other. Been there. Not much you can do.. "His thoughts tumbled in his head, making and breaking alliances
