I can see that smoothness is important for the kind of shooting you do, but many of us don't earn our living by shooting stylished ladies and gentlemen for living. Personally I am mostly shooting landscape as a pastime (earning my income in reactor physics). Some people shoot architecture or food. Needs are different.
I agree that everyone not only has different expectations and sees different things.
The only point I was trying to make is compared to the contax zeiss the phase (non leaf shutter lenses) are 4 times the price and I'd love to see even equal the performance.
The Phase 80mm is a 2.8 the Contax Zeiss f2.0, which makes a big difference.
The Phase 150 is $3,490 the Contax under a thousand.
Then there is the ergonomics. It takes any photographer about 10 seconds to get use to a Contax with f stops on the lens and a shutter dial. You can swap finders from prism to waist level and the contax is smooth and substantial.
After 15 years you expect a leap forward and it's not just the Phase mamiya, dslrs have gone the same route of dials and menus to replace analog functions.
Shoot a contax 80mm close up hand held at 1.30th of a second and you'll know what I mean.
It's the same thing with those little m43 cameras I use for video and stills. Take the olympus em-5 and use an olympus lens. It's sharp (over sharp for me) medium fast though not crazy fast though autofocuses immediatley and is easy to use.
Though put a lecia or Voigt manual lens on it with a f stop ring and the camera transforms into analog, shoots like analog, looks like film. Sometimes I think we're answering questions that nobody is asking.
P.S. Once again this isn't a dig a any company and obviously contax is gone, gone, though the camera still live on.
What I'm saying is unless there is a real leap, something you can't do without or have to have to make a certain image, there is no reason to change.
If I needed leaf shutters, I'd look at the DF, well maybe, but I don't need any sync above 250 and can overpower the sun easily with a contax and 2400 watts.
