Microadjustment

L plates still on
Canon 7d vs 100mm macro EF IS USM...
didn't seem to be getting on with focussing the damn combo.... eventually worked out about microadjustment.... on AF, the combo was focussing 6-10mm short!.... took a while to correct, but now with a microadjust of +20 it now focusses at +/- 2mm at f3.2 on a subject 62cm away.... should auger well for next season..
whilst playing.... the DOF increase with each stop of aperture narrowing seems to be ~ 1mm from f3.2 - f5.0, then 2mm from f5 - f8, then 4mm to f10.
Is that what I should expect.?
I think I should try to keep the iso at 100, and the f as low as possible for flat subjects, or ~9 ish for angular shots, letting the camera choose the shutter speed. Would the in-built flash be useful to fill in the subject at ~60cm distance to target?
Does that make sense to all those who are experienced with DSLRs. I am sure anyone making the leap this way would be pleased to read any comments / advice regarding the above.
Maybe I should come to the workshop next year
.... such a long way when negotiating with SWWBO ![Rolling Eyes :roll:](./images/smilies/icon_rolleyes.gif)
