i dont think it can come off beta until we get some proper raw converters either
so a question for those that have focal, is it worth it?
do you get significant time saving benefits when calibrating a boatload of lenses?
is the accuracy significantly better than other methods?
It does not depend on outside software, it probably uses jpgs from the camera. that does not matter, since its merely finding the sharpest setting.
As to benefits, YMMV. Some lenses are close enough out of the box to be fine, while some, particularly wide lenses do benefit. I found it to be much more precise than methods that require me to visually decide which image is sharper and found that I was sometimes way off. In other cases, my AFMA with lens align tool matched perfectly.
One of the side benefits is that you can spot focusing issues in your camera / lens combination. We often hear of users who do not get consistent results.
The two photos of my laptop screen below show that one has a smooth curve with few inaccurate images while another lens struggles.
Reasonable curve I believe that was my 300mm f/4L, my only lens to have 0 AFMA on both 7D and 5D MK II. I sold it to finance my 5D MK III.
This one is ok, but the lens had issues, probably due to vibration of me walking on the wooden floor during one of the test points.
