Barlows, Powermates Comparison

Hi Folks,

I hope everyone is happy and well. Here's something I always enjoy: an interesting comparison- this time between various barlows and powermates. I'd like to do something similar for teleconverters one day.

Take home message (surprise surprise - NO); you get what you pay for. Happy reading.

Best
JA

Great comparison with some decent "objective quality evidence" as we might call it.
