The 35mm lens at $200-300 "is" the cheap one...probably the f1.8. Trust me, the 35mm f1.4 and better go way higher! In the Nikon world the f1.4 goes for $1400; Sigma for Nikon is at $900. And these are not Cine lenses; rather, they are the regular lenses. Both Canon and Nikon have multiple levels of lenses in this respect. That said, the f1.8 lenses are more than adequate for 99% of the type of work you want to do and offer great low light capability. (albeit at very shallow depth of field when opened up that far)
