    check the shutter speed settings in custom functions 2 to see if it is set to a particular speed.

    Given the "reasonable" pricing to mod your camera sensor using companies like Spencers (https://www.spencerscamera.com) provides many...

    I do wonder how diffraction in practice seems to be less of an issue for higher mp sensors than the maths would indicate. I like f16...

    Diffraction is based on the size of the photo site. For the same resolution sensor the site on an APS-C is always going to be the same...

    Be nice to see Astro versions of cameras again like the eos Ra or no AA filter versions like the 5Dsr maybe an R5a or R5sr based on the...

    For FoV but it's not the core of the message here. Regarding the "2 stops more" I sincerly doubt his numbers are correct. You let more...

    1.6 squared is 2.56. The base 2 log (i.e., stops) of 2.56 is 1.356144. I round that to 1-1/3 so it translates to camera-based 1/3-stop...

    Yes, for total light gathered (light intensity * exposure * sensor size). If aperture and exposure are the same, that's log2(1.6²) =...

    The long end of the 100-500, when used on APS-C, gives an FoV equivalent to 800mm on FF, but the f/number remains f/7.1. Thus 800mm...

    When using a FF lens on an APS-C sensor, the light intensity on the APS-C sensor is correct for the selected F-Stop. But that extra...

    Aren't you mixing up things? Where does 800mm f/7.1 come from here? Where does that come from? Aperture dictates light intensity...
  • B
    Yeah, i think making it 100-500 instead of the usual 100-400 was a brilliant idea.

    What i want is "cheap" PowerShot with a decent lens with at least 200mm at the long end. Doesn't have to have big sensor, something like...

    No, and I use native RF lenses now.

    In terms of signal/noise a 800mm f/7.1 is equivalent to a 500mm f/5.6, ie 0.7 stops faster than than 500mm f/7.1. So, in fact the...
