Camera is a Canon PowerShot SX730 HS F-stop 3.3 Exposure 1/160 ISO-80 Focal length 4mm taken in full morning sun light, no extra lenses, fly behaved reasonably well with me being so close.

Being a PowerShot I use manual and practice as often as possible to get the photography, some good lessons learned here in Steemit by @keithboone a year or so ago.
