Manual focus on a DSLR.

Here is the E-M5 one which is obtained via one of the art filters. In this case the camera is set to use the filter on the jpg so the real shot has to be developed from raw. The other way just activates the filter when one of the programmable buttons is pressed.

Dan,
I hadn't understood it completely your affirmative, and because of it, I opened the new thread https://www.cambridgeincolour.com/fo...hread36203.htm.
After Kathy's explanation, I understand what you said.
Thank you very much,
Antonio.
