Originally posted by vonBaloney Are you saying that the dot is on at +6 and -10 but not in-between those? That doesn't make sense. Also a chair is probably not the best target unless you are focusing square to a flat surface of upholstery maybe (with a high-contrast pattern). There should be a whole range of values (of maybe 4-8 points, but a slower lens will confirm more points) where the green dot will show (and those should be adjacent to each other), and some where it confirms instantly and some where it takes a second (which should be regarded as secondary confirmations) -- you're looking for the center point where an in-focus target is instantly and solidly confirmed (no flickering). Remember, set the aperture to max and make sure the system is off (not confirming anything) each time before you hit the shutter half-press.
Or, if you mean it is confirming between +6 and -10 (which should mean it is instant and solid around -2/-3), then I would put it there (-2 or -3) and see how it goes...
the green dot confirms at -10, all the way to +6. I can't go past -10 to know if it would not appear at -11, because I can only go to -10 (I feel like there is a Spinal Tap joke in there somewhere) mine confirmed instantly on those. so at 0 to +6 it was solid green right away, at +7, there was nothing, no dot at all. from 0 to -10 there was also a constant green dot, with no hesitation or flickering. I waited for the meter went off before confirming again.
the chair has a thin high contrast flower pattern pad on it, but not flat as a wall, so I will test again with an actual test pattern, this was just a test for the process and I am very impressed how easy, in general, it was to do.
