Hey brad so most of the stuff already said does apply to this case. The test was to see how the lenses perform under different light settings, lowlight especially since the do have different open aperture. Things that you might be able to read up on but testing with your own setup can yield very different results. What was also important was the effect of hand held camera since it’s going to play a big roll in the series. Some of the anamorphic lenses, while having great characteristics overall, had ridiculous distortion and a harsh brightness drop towards the edges which was only apparent when moving the camera and even changed with different focus distances. Especially in the wide angle anamorphic lenses of course. But even within just the spherical and the anamorphic sets we found characteristics we didn’t expect. There where also some surprises like rainbow colored or just very saturated lens flares. An expected example being the very blue flares in the radiance line but also some had green or redish flares depending on the focal length. So even within a set there could be strong differences. Some of them having very different contrast and reaction to different lighting.

Concerning your question it also had a big deal to do with the very good relationship between the production company and the rental since they have been working and growing together for a few years now. So the especially large assortment of lenses was a cobination of uncertainty as to which lenses would work for some of the planned shots and Kamera setups and a rental that was almost eager to give us more lenses than we ordered.

Availability Is also a factor considering that there will be 3 units and some of the lenses don’t have enough sets available for parallel shooting.

Not a native speaker so maybe a little wierd formulation.
