I'm not sure how to ask this other than "What are these big lenses?"
One of the comments mentions that they might be Zeiss. I'm not sure how to tell.

They're both Cine lenses mounted on Canon 1DCs. The 1DC is a variant of Canon's 1DX flagship DSLR, which can shoot 4K video using the central APS-H region of the 35mm sensor.
The one on the left is an Angenieux Optimo 12x, a very high end 24-290mm T2.8 cine superzoom lens:
The one on the right is a Zeiss master series T1.3 prime lens, probably the 12mm:
The T1.3 specification accounts for the size of the lens - T1.3 means a t-stop of 1.3, sort of like a f-stop but based on the measured transmission of light, not the aperture size alone. A T1.3 lens is most likely f/1.2!
I'm afraid you can't afford either of them ;)
