What apertures are required to enable autofocus, including cross-type or high-precision focusing, on Canon DSLR cameras? What about lenses that aren't manufactured by Canon? Does e.g. Tamron 17-50mm f/2.8 enable use of center high-precision point in xxxD/Rebels? |

Why is there an ISO setting when shooting raw? I think that what I wanted to know is really the thing that actually changes when you change the ISO and, importantly, how it affects photon counting in a way that makes ISO impossible to adjust in post. I gather that it's about voltage levels in photodiodes in CMOS - it gets lower with increased ISO, so it's more likely to count things that aren't photons entering through the lens (i.e. noise). The question then becomes why can't RAW files record voltage levels instead of photon counts? |

How can I make phase-detection AF more accurate with a Canon 650d and 50mm/1.8? Didn't try it but I'm going to accept anyway. Sounds sensible. When I get around to actually doing it, I'll try to remember to update this question. |

What advantages does 35mm film have over high-end digital? leaving this here for future generations: clarkvision.com/articles/film.vs.digital.summary1/index.html |

How to understand the picture height? line pairs per millimeter should be the most generic, because it's independent from sensor density. OTOH if your sensor isn't dense enough, you won't be able to discern pairs from each other... |

How can I make phase-detection AF more accurate with a Canon 650d and 50mm/1.8? @jrista: Yeah, it wasn't sunlight, but it wasn't dark either. If I understand correctly, I need new lenses if I want to use a body with PDAF, or I can pretend I have a mirrorless and shoot with Live View. Correct? |

How can I make phase-detection AF more accurate with a Canon 650d and 50mm/1.8? yes. they were all taken using a tripod, with a remote release cable and with mirror lock-up. |

Is there any filter opposite to Polarizing filter, to emphasize reflections? i stand corrected. for some reason i thought that circular filters are polarized, well, circularly. |
