Re: 5D MK IV - focus confirmation with third party lenses in MF mode

Just in case if you wanna adventure. (not quite)

 

Instruction regarding installation and programming in PDF are everywhere online. Initially, I program the focus adjustment value to 24-25 and it should be okay. Since the DOF of f1.4 is thin, after in-focus is confirmed by the chip, you may step down to f2.2 to 2.8 to allow more (accurate) focus tolerance. Or, use live view to confirm accuracy if you need to shoot wide open.

 

Manual focus photography is not for fast shooting. You will learn to be patient. Take your time and enjoy the art of photography.

 

One reminder : watch out the thickness of the shim cardboard. Thin cardboard is enought o hold the chip. If it is far too thick, you risk the chip crushing the pins on the camera.

 

Also I won't scratch the mount (as shown) to stick the cardboard on it for obvious reason. I use a toothpick and tiny droplets of superglue (gel type) and it works.

 

Enjoy.
