Also, does anyone know the difference between the Panamorph ATH1 and the ATH2?
Sent you a PM - I do have some heavily discounted transports for sale. I used to be head of Panamorph sales and marketing between 2008-2012.
The ATH1 and ATH2 are essentially the same, with slightly different aesthetics. The main mechanical difference is that the ATH2 can reverse direction during its traversal if you change your mind about whether you want the lens in or out.
