MA Inconsistent

You’re welcome.


Also, Even though the camera adjusts MA adjust for focal lengths in between the wide and long ends, it is a linear adjustment. E.g. -3 at the long end and +3 at the wide end would most likely result in 0 at the middle , but what if you find out that the need for adjustment is not linear? What if you need -3 at the long end, -3 at the middle and +3 at the wide end?

OK I got the concept on how the dock works. As expected has to be verified using the body. Thanks for the linear vs non-linear explanation. That is a lot of MFA to do but with patience good payback. Too bad everything is going ML because I could see FoCal getting involved with this. I expect to see them to fade away unless they can take advantage of lens deviations with ML bodies. Maybe to measure for a decentered lens.

Thanks for the info.

I've yet recal my 35mm but it's on my to do list this weekend. While I'm at it, I figured I'd do my others also. When I calibrated the Sigma to my 5Dc I didn't have LV which is why I got it right. I was told I could use LV but after reading everyone's post I now know not to listen to that person

I finally dialed it in but now I'm looking to sell it for a 50 or 85 f1.2.
