Re: I'm not questioning your testing methodology.....

Like I said, there was no cherry picking.  The Speed Booster is my one and only personal sample.  I've had it since last summer, and it was given to me - I didn't buy it.  It was selected at random from the normal production run.  I purchased all the other focal reducers online, just one sample of each.

The primary result of sample variation is uneven corner performance due to tilted and/or decentered lens elements.  This is why I took the trouble to show all four corners and both sides in my 100% crops.  This ensures that you don't just show the worst corner or the best corner etc.  This helps to prevent sample variation from degrading the value of the test.
