Thanks for the input Sam.
Yes, our meters read exactly the same; f8/11 split, with the ASA set at 80 to take into account that my S8 camera's shutter angle is 150 degrees, not 180.
Keep in mind that I'm shooting Reversal Stocks--Plus-X and EK 100D, both rated at 100ASA--so my exposures need to be dead on, not 'hotter'. By 'hotter' I presume you meant overexposing??
Ah, but of course--the Teleconverter!!! Hmm, now I'm curious to see what reading the in-camera meter will give me without the Teleconverter. But then, as Fred cautioned, the moon will take up even less of the frame, even if it's centered, and therefore the camera meter might weight the reading more towards the night sky.
All that said, would you recommend shooting at f5.6 with the Teleconvertor, or staying at f8? Of course the test roll will bear out the results, but I'm curious in the meantime.
Re flare, I have a second Canon 1014xls and it bears the same artifacts, so I don't think there's something 'wrong' with the lens, rather it's not a pro lens. Though as far as S8 cameras go, it's among the finest.
