Has DJI tweaked any focus algorithms in FW v.01.00.0500? I was testing yesterday by inspecting my roof and the focus seemed better.

Focus seems fine.  Can't say I've noticed any lack of focus on mine, before or after updating.

For me, AF was constantly jumping in and out of focus. Even tapping the screen only focused for 1 second.

It does seem the focus is a tad better after updating to .0600

If the update has solved it for you, so much the better

Cant say Ive had a problem with focus.  

This one looks good indeed.
