and THIS is exactly why you need Lens Align - there is simply ***NO WAY*** you are going to get that video box ***EXACTLY*** perpendicular to your camera/lens at the distances required (say 8' or so for a 100mm lens).

That is EXACTLY what the Lens Align system does - ensures that the camera and the target are PERFECTLY ALIGNED.

:cool:

Wooo! Panic! I didn't have my focus target PERFECTLY ALIGNED! Woe is me! Waily Waily.

Hang on a mo. When I did my friend's 1D MkIII and 300 f/2.8 I didn't seem to have any problems doing it using a Mk1 eyeball.

Nope, the focus looks to be the same across the whole target! How strange, because it wasn't ***EXACTLY*** perpendicular?

Hmm, I wonder if it's got anything to do with the fact that the depth of field at 50xFL and f/2.8 is 29 cm?

I have the Lens Align PRO...

In my opion the thing was put online for sale in development stage. Instruction next to none came with it ..I found a crappy video on "your Tube". I had to play it 5x to make sense out of it. Also they dont make clear what distance. 50x 25x 20x for lenses. For a 500 lens you have to stay in the street at 50x. I bought mine for $120. It came with a short ruler. 2 weeks later they came out with another attachment "FREE" but charged me $5 for shipping. There was a 40 cents postage stamps on the envelope!

Also another kit 2 weeks later a long lens ruler.

All too much like amateurs.

These guys don't have their act together!
