>>2886014I mainly do video and sometimes take timelapse/panorama shots.
Right now the filter I use bring down the light by about one stop.
In one test it changed the "sweetspot" that the camera tested from 1/4s to 1/2s and in another from f/10 to f/7.1.
It does a good job making trees perfectly green and roofs perfectly orange/red, so I guess it's at least good at that.
I made this picture, comparing two shots and I think the CPL might actually cause some sharpness issues, tho I can't exactly judge because of the increased exposure times
When zooming way in one could see that with the Filter, sharp lines would sometimes have an extra pixel of grey area.
Doesn't seem like a big deal to me.
Might it interfere with Autofocus?
The exposure times here are 1/8 vs 1/3 and 1/800 vs 1/250. I put the exposure time at the Sweetspot for the text and for the building at the lower end of the recommended area.
