My Name is Giovanni Baroni, Im a professional photographer, doing mostly events like you find on this site, but also shootings. Useing mostly mirrorless technology for my work like:

Sony a7s, a7s2, a7r2, a7r3, a9, a6000
Fuji XT1, XT2, XH1

My style for shootings is mostly against the light (sunlight). You'll find an example shooting Album here:

I mean one of the main advantage in mirrorless technology is WYSIWYG (what you see is what you get)... thats why i play alot with flares and stuff.

Shooting with the Sony A9, GM 70-200/2.8 and other Lenses i got some problems sometimes with stripes through the pictures.

Shoot with Electronic Shutter (standard), available Light, 1/250s, Handheld, uncompressed RAW

Picture's are not edited, just slightly developed in Lightroom

The problem seams to be a real problem for me, cause of the way i like to shoot. I could accept a workaround in postprocessing, but so far i haven't found one.
