I am late pitching in here, but I have been reading some posts here with interest and have a question please.
I have just purchased and had delivered from the US LensAlign and I also bought the new Michael Tapes' FocusTune. It arrived this week and I am strictly following the instructions to the absolute letter. I will report back on that journey when I get satisfactory final results. At this early time I seem to be trusting the manually viewed LenAlign images more than the FineTune results. It's early days and I have a lot to learn. It still leaves me in a quandary about what to do with zoom lenses unless, I just test at the most used focal length as results are showing major changes of AF-fine tune settings between a focal length of 24mm and a focal length of 70mm on my 24-70mm f2.8 lens! My prime 300mm f4 and 50mm f1.8 both showed no adjustment was necessary on both LensAlign and FocusTune.
Reikan's FoCal Standard application seems a reasonable price and a lot quicker than any other method. Allowing that it's brand new technology, has anyone here experience of both LensAlign and FocusTune and if so which would you recommend?
Now, I have always been shy of AF fine tuning, but I do freely admit that my insatiable appetite for knowledge finds the various methodolgy interesting. I have dismissed LensCalc because of adverse reports. I haven't any issues with my lenses to my knowledge, but I am sad enough to while away the long winter evenings as part of yet another learning photographic exercise
Finally, I agree with Eric Bowles that the whole issue of fine tune could perhaps bear its own forum. I've gone from little interest to being totally fascinated by the whole issue. It must be the Instrument Engineer still in me and the quest for total accuracy coming out again after a few years break!
