An observation about AF-C at Pentax K3III
2

I remember Pentax had problems with artificial light at AF, at one point, which was fixed with a firmware update. I have the feeling that the same problem is even at certain times of the day, in sunlight, ie at certain wavelengths of this light, which sometimes exists. Today I checked for Kobie K3III & 150-450mm and it worked incredibly fast, I couldn't believe how fast this combo had focus. Here we have a period of rain that lasts 2 weeks, and the air is probably very clean, something is happening beneficial for AF-C, I was amazed afternoon around 16 o'clock.

Best regards, Valeriu
