Re: Here's what the M8 firmware does for red vignetting
I really appreciate your effort, Scott ... but with due respect, the usefulness of these on the fly tests is very doubtful because the error in measurement is totally out of your control. There's no way I'll believe the light falloff is zero even at approximately 25% away from the center of the 28 cron ... just for the record, here's the factory vignetting chart of both lenses. Stopping down from f2 to f5.6 does improve a lot for the cron ... curiously, f2.8 down to f8 doesn't make much difference for the 28 elmarit asph ... so how much help the 6-bit coding could lend in this particular case. Sorry ... I just don't get it.
