As video lenses they're actually quite cheap (look at EF & PL for C300), however, from a stills photography perspective they're a lot cheaper than the new 6D -> who said that you should not scrimp on glass and that you ought to spend nearly as much on the lens as the camera body? Lots of DSLR Photography training books do. No point on having a nice new FF body with improved IQ and putting cheap glass on it. Seriously, amortize these lenses over 3-4 years then factor in the re-sale value....less than $4/week.
