I don't know... seemed like there were some bits of usefulness in the write-up.
That said, I've only seen this lens in pictures and auction listings. I've never used one or even touched one. I haven't looked into renting one, but that could be neat.
I took the sample images as examples of everyday uses for this lens, for those with the means to afford it. I wasn't expecting art-quality images with weeks, months or years of composition time or thought.
And for what they were, the images looked good here on my end. I'm not downloading the full res samples, though.
