Try stopping down to f/8 and try with a 105 rather than a 135.
I was surprised myself, I wasn't expecting to repeat Shel's 
observations.
I wasn't able to repeat it with my LX, MX or ME Super.
I do have one of the accessory screens in my istD, though I don't know 
if it has a different tooth compared to the stock screen.
