NiSi ATHENA Prime Cine 85mm T1.9 Reviews

LOVE

By Matthew
Rated 5 out of 5

For the price, these lenses are unbeatable. I absolutely love them. Great look, even wide open. Smooth action. Great build quality. My 85mm, mounted to a Canon c70, took a hard fall onto concrete on the last shoot. It's got a dent, but that bad boy is still rocking like nothing happened. Absolutely would recommend these gems to anyone looking for a fantastic, all around cine lens option.

Bad Batch or Poor Construction?

The lens I received made a scraping noise when the focus ring was turned. This is unacceptable, especially for a cinema lens. I returned it. The replacement lens I received makes the same noise. I own 25mm and 40mm Nisi Athenas which are silent and smooth. Either there was a bad batch of 85mm lenses along with poor quality control, or this lens is very poorly designed and constructed and unlike the other Athena Primes.
