The focus on differences in the f/16-f/32 range is utterly crazy. It also would be interesting to know what the % numbers are.

I suddenly realised that you may be refering to the "stacked converters" tests: if so, when you stack converters, the maximum aperture shrinks correspondingly. In these cases, f/16 is the biggest aperture possible with this lens/converter combo, so higher values do not exist.

Cheers
