As someone who has not shot any video on my DSLRs, can someone explain to me the value in spending 4k on a 50mm zeiss lens to mount on a DSLR that is going to down sample the image to 2 mega pixels?
Because its not all down to dslr now is it.... The Otus will work wonders on a RED or Sony F55 and handle very well...
Have you seen the focus throw on the Sigma? Its litteraly like 20 degrees or something like that.
For video, being able to find focus very accurately manually is key. If moving the focus 2-3mm means moving sharpness 1-2 meters then the lens is useless for accurate focus. That whole in and out of focus thing that comes from people with no experience or proæer gear.... Its not charming, its bad craftsmanship.
The Otus performs close to the ultra primes, its solid metal all the way, the focus ring is incredibly smooth and the focus throw is around 270 degrees and damn precise.
If I was only shooting stills and needed AF, I would consider the Sigma. But since I mainly do video on various cameras from dslr to sony yo red, the Sigma makes NO sense what so ever.
