Where can I find the MTF curves of Phase One Schneider lenses online?
I neither see them published on the Phase One site (or the downloadable lens data sheets) nor at the Schneider site.
Don't worry about the MTF charts. As far as sharpness, fine detail and contrast goes they are excellent lenses.. The 110 inparticular.
The one thing you want to look into or consider is the Iris. The LS lenses I have tried have only a 5 blade iris.
This results in not that good bokeh and small out of focus high light rendering. Pentagon shapes rather than more pleasant circles.
Wide open they are nice, but stop down even one stop and the pentagon can show up on any defined out of focus highlights.
Here is a previous thread.http://www.luminous-landscape.com/forum/index.php?topic=67434.msg533454#msg533454
From that thread:
Example of 5 blade iris
Example of 9 blade iris
I wonder why Schneider chose a 5 blade iris in the Phase One Schneider designs when on their cine lenses they go
as high as 18 blades.
