Using the longer 3/4" B4 lens for telephoto work, and the wide 4.4mm 1/2" B4 lens for wide angle work, you can see how the color, contrast, look and feel compare in this video.

All shot on a Panasonic GH4 in UHD (4K). Camera files dropped into a 1080p30 timeline. No color correction at all. One shot was used at 100% (1:1 pixels) the rest was scaled 50% to fit the 1080 frame.
