Lens Test w/ Zeiss ZE and CP2′s, Canon L Series and Leica R Glass

west

Part of being a cinematography intern is not only knowing all the gear, but how it can be used to enhance your visual story telling. The characteristics of a lens can infuse a mood, a style, etc. Being obsessed in the subtleties is key. Shane encourages us to use all our tools and test them in the line of fire. We have been using Canon, Leica, and Zeiss lenses but haven’t had the chance to compare them all side by side. Shane saw this as a good learning exercise and asked us to put together a lens test. We used 18 lenses, lit the scenes with our home depot lighting kit, and spent a day shooting four scenarios to compare the aesthetics between the lenses for video. We kept our settings consistent between the lenses and here are our results. Take them with a grain of salt as it’s not a definitive test but more of a practical observation.

This was all shot on the Canon 5D Mark II with the Neutral picture style, and all of the footage is raw with no color correction.

Conclusions:

Canon

Overall the Canon glass produced great skin tones and colors. The reds seemed to be slightly more saturated then the other lenses with slight bleed between red and magenta on our color charts. Very sharp images as well from the primes and the zooms were a bit softer. The images were almost too sharp in some cases which caused small amounts of moire in hair especially. Also the Canon lenses tended to breath more than the others.

Leica

The Leica glass produced creamy looking images with wonderful contrast and colors. Though the lenses were contrasty we found that they had a great fall off and gradation between colors and luminance which held detail very well. Overall they were slightly warmer in color temperature and very prone to flaring. We did not use a Matte box for this test, which would have cut out a lot of the flaring. Also out of focus highlights have more of an octagon shape due to the lenses having fewer iris blades.

Zeiss

The Zeiss glass produced Sharp, snappy, and contrasty images. Slightly cooler in color temperature as well. The contrast was problematic with shots with strong highlights as it seemed to lose some detail in the highlights. The ZE 35mm F/2 produced a str
ange halo blooming type flare which could be problematic depending on your shooting situation, personally I liked the aesthetic. The CP2s were less prone to flaring due to their build, and had very smooth out of focus highlights and bokeh.
