Good. to know. Thanks.
There are two E-M1 listings in that table.
"E-M1" Preliminary Support since 5.2
"OM-D E-M1" fully supported since 5.3
I assume the 5.2 reference is outdated and should be removed.
Like you, I'm never entirely sure what Adobe means by Preliminary Support and whether its definition differs on a camera by camera basis.
