Hi Ed:
No worries. We understand that it is often more comfortable to get basic info from a forum environment where you can take your time to read, digest and try out the various recommendations *before* you lean on your vendor their more directed help. Also, in the forum you get a variety of suggestions that may or may not be part of the vendor's workflow protocol, which may or may not better suit your working style.
That said, here is my .02:
First you need to confirm everything is properly calibrated -- meaning when the lens is focused at the 3 meter mark, is it really focused dead on at 3 meters, and when it is focused at infinity mark, is that really infinity? You can check that by shooting something 3 meters (or whatever the mid-range mark you want to calibrate to) distant as well as something very distant with detail, like a metal power tower. Shoot several frames adjusting focus minutely between each shot. I shoot a first one "on", then two closer, then two further back, moving the focus ring about 0.5mm between each shot. I then check these on the rear LCD. If one looks good, I move to the other point and repeat. If none of the first captures look good, I would repeat with a bigger series focused closer followed by a bigger series further until I could determine which direction the lens was off, then I'd try and zero in from there. If it's off (which I have seen more often than not) you may want to make your own calibrated zone focus scale using tape over the factory scales with hash marks at your most-used shooting distances.
*Note this is my biggest issue with tech cameras -- you can never confirm 100% perfect focus unless you are tethered and do a review onscreen at 100% view -- so the focus is at the very best an educated guess you hope is close enough and has enough DoF to carry the day. Fortunately with shorter lenses it is often good enough. And admittedly I am a tech-camera cynic so you may want to ignore everything I say...
Assuming the camera is all zeroed and true, my basic workflow is as follows: Compose, set lens and shutter speed and wait for the desired conditions then capture. Immediately after that capture, slow the exposure time 2 stops, place the white sheet over the lens and capture the LCC frame.
Hope this helps and congrats on your new tool!
