On the Internet, there are a ton of evaluations and enthusiastic declarations that this glass is fantastic and that nothing could be finer. Everyone talks about extreme sharpness, loudness, etc. The reviews, in my opinion, are either fabricated or reflect people's attempts to deceive themselves. It is unfortunate to pay $130,000–$144,000 and receive a defective lens with an open aperture.
