Just wanted to see if there was an obvious drift. I know many people use MFA but I have never really towed the line on that one and usually pay the price. No one likes the rebel. I don't have anything sophisticated like Focal yet. My biggest beef to date is there were so many methods by so many people and so many focal length recommendations. Dot tune, etc. Tried them all except Focal.
First of I know light on the target is critical. I have found different results every time I retest it. I very carefully tested my 100L macro at different distances and all yielded different results.
I might be crazy but if spend $5000 on combined equipment I prefer it calibrated in a controlled environment where trained technicians measure it at multiple focal lengths. I have found that if this is done correctly even in two separate departments it may only need one or two ticks which is nothing. I am aware of lens and cam spec variation. I can see a big benefit for 3rd party lenses and saving a ton of money by doing it yourself.
I may get Focal but is is not fully automated as advertised for the 5D3 last I read. Not sure if it will be for the 7D2. Or the Michael Tapes thing. I already have Focus Tune but not the latest target and his new ruler system. It is less expensive and provides graph information not only the target but the ruler readings as well.
