I photographed a spotted flycatcher this morning. For weeks I have been fighting high ISO values because I am too stubborn to adjust ISO each time manually. The Canon R5 kept pushing into the high ISO range while the photos came out only borderline overexposed, and I could not work out why. Jasper noticed it as well when I sent him my photos. Exposure compensation is at 0, the ISO limit is a fixed value and not relative, so a high upper limit should not change anything further down. This photo, taken in broad daylight, still came out at ISO 5000. In manual mode I usually care about the shutter speed, take the widest aperture the lens offers and leave ISO on auto. After some back and forth I found it, with the 1.4x extender f/13 is the widest aperture the 200-800 offers at the long end, and when I took the extender off, the camera kept f/13 and I never noticed. The pied flycatcher earlier this month was the first photo without the extender, the one where I already wrote that the ISO jumped way too high.
