I think Lensball says it right when they say “Lensball is for everyone”. Not because I recommend professional photographers to use Lensball, but because anyone can use for any use.
In this video, I offer a brutally honest review of the Lensball, from both a professional photographers point of view and just any photographer.
Get Lensball on Amazon.
*** Correction: The Lensball costs either $29.99 or $39.99. ***
