HI Martin thats very interesting. I have downlaoded the trial version but dont think I know how to drive it properly is there any chance you could try and anlayse my "66" FF III setup (canon 350D) to compare the result to steves?

The top two look good. What is that 3rd one all about?

Thanks Martin

I don't know I was hoping soemone could tell me

So the setup isn't too bad? or are there things I need to do to the setup?

Apologise for not being able to interpret the results should RTFM is suppose...

Here is an interesting link looking at comparisons of the WO F/Rs along with a TMB. Interesting reading.

Thanks Martin

Martin, thanks for running the image through your software - very interesting result. I have just collimated my laser collimator (no visible rotation at 20 feet) and am going to collimate my ED80 now to see if that is where the fault lies.

Once I have that done, I shall try it again.
