Not necessarily. I am running trials right now , witha Nikon D4s and 50mm f/1.4G lens with the updated software and these three target and ruler configurations"
- Mark II target and ruler
- Gen 3 target + mark II ruler
- Gen 3 target and ruler combinations.
My understanding is that the purpose of the Gen 3 target and also the Gen 3 ruler is to make it easier on the AF system and for FocusTune to do various functions. I like the LensAlign and FocusTune combination and find it very reliable but the documentation right now could be written more clearly.
I look forward to your results. I've been using LensAlign from its first days and was always satisfied with it. FocusTune was a big timesaver, a real improvement.
