Sun flares are a strange one. Lots of lens reviews mark lenses down if they produce too much flaring. Usually for me its the opposite. The more flares the better.
Obviously it has be be controlled to a degree otherwise the flare takes over the image. I think on a shot like this with a beautiful model like Katie there's no risk of anything other than the model being the main focus 😄
I've been looking at few of the old Russian M43 lenses recently like the Helios 44-2. It looks like a really fun lens to play with and really cheap too. I know its meant to flare up really easily but I think I might like that. I'm watching a few on ebay now so I might end up buying one soon.
