purple dots shower

[ugobeck]

hello everybody, this is my first post

 

I started today taking pictures with a A7ii, and I was suprised of this result. In other backlighted scenes I can see some purple dots, but this shower is unexpected. Other picks are gorgeous

Are these created by software? What is the raw file like? If you do not have a raw file, it may be worthwhile to change your camera settings so that you shoot RAW+JPG. Take a similar shot and compare RAW and JPG. Perhaps the RAW file will be ok. Kind regards, Freddy.

It is the lens. Looks like very bad red/green CA - like this:

Agreed. No question, no doubt.

 

Not sure why he's working at wide aperture like

that when he's got such an unnecessarily fast

shutter speed. But that IS asking for trouble.

Since it's very visible right in the middle of the

frame it's longitudinal CA and so stopping down

is worthwhile.

Golem is right, but I was just playing around. And, with your help, I learned something valuable. Thank you
