Cinema lenses are made for a variety of reasons. They match physically, or al=t least their controls usually do, they are often colour matched, some even match in Bokeh and other characteristics and they are generally consistent in focus throw and feel.
Cheap cinema lenses will provide some of those benefits, but not all.
The two Spectrum lenses are gorgeous physically, feel solid and smooth.
They are however, far from colour matched and they have a little focus breathing (but I knew this going in).
Top row; the 35 as shot and graded quickly.
Bottom row; 50mm as shot and poorly graded (too much magenta).
I think with pairing these two, the 50mm with a light grade will be my base line, the 35 will then have to come to it (graded 35 and ungraded 50 look close).
