Lens Alignment - Focus Tune

June 12, 2013  •  Leave a Comment
Since my lens is an old non IS 600 F4, I decided if any lens would probably need a micro adjustment, this would be the lens.

After a ton of searching I decided on the Lens Align MK II tool from Michael Tapes Design. So I ordered it and put it together in only a couple of minutes.

One of the things I quickly found out was, my eyes weren't what they use to be. I'd set everything up and it seemed the more I stared at the screen, the more I was seeing things :)

Luckily, Michael also has another product called Focus Tune. Simply, the photographer takes 4 shots at adjustments -20, -15, -10, -5, 0, 5, 10, 15, 20. Then let Focus Tune import the files and decipher what
might be the best value to use. That definitely saves my eyes :)

Everything works great except for one thing...the documentation...or more to the point, no documentation. At a minimum there should be a guide that comes with the software.

That brought up the next problem. Finding the 'correct' documentation. All I could find was the documentation for 1.0 with a note that 2.0 was being worked on. If your documentation isn't ready, don't release the software, cause that brought me to the next problem.

I was getting an error when I tried to have Focus Tune evaluate my images. I went to the web site and searched for the error. Turns out there is a 2.0 manual, but the only way I found it was via that thread
I was reading in the forum. Which as it turns out I found out I just wasted at least an hour of my time
because of new recommending settings.

Now I have to start all over again.

The tool and software, I'd give that an A. The documentation, I'll be generous and give it a D+.
