I cannot help wonder how many IQ250 Phaseone still manages to sell with this price difference.
The only measurable advantage it probably still has pretty much boils down to C1 pro support. Is that worth 20,000 US$ that buys you a whole lens line up?
A few advantages of the XF + IQ350 that you missed (most of which also apply to the IQ150 and IQ250)...
- Digital Body Platform built in 2015 rather than 2002*
- Digital Back Interface built in 2011 rather than 2004*
- Faster Autofocus
- Improved Ergonomics
- Built in Profoto Air Transmitter***
- 1/1600 sync instead of 1/800
- Blue Ring Lens line which is a step above the build quality of any previous Hassy or Phase lens
- Option to use focal plane lenses up to 1/4000th of a sec (H body only accepts leaf shutter lenses), including some random/exotic lenses like the Contax 80/2 (remounted) or Schneider 130mm IMAX Cinelux (see
see here)
- 5 year warranty, including unlimited loaners on any back/body/lens that requires service**
- Metering when using Waist Level Viewfinder
- Focus Mask
- Customizable Exposure Warning
- Customizable Clipping Warning
- Exposure Heat Map
- Customizable Grids and Guides including option to drag a guide to a custom location
- Buttons which are easy to use with thick gloves on (when touchscreen isn't usable)
- Built-in Perspective Correction and Horizon Correction when using Capture One
- Complete duplication of the camera interface on the digital back, in the case that the top of the camera is not easily viewable
- Complete duplication of the camera interface, including camera preferences like button assignment, from Capture One
- Super fast transfer times when shooting tethered due to use of USB3 rather than the legacy FW800 spec****
- Support for USB3 1.2BC which allows you to power the back and body from supported USB hubs
- Direct setting of aperture from a hard dial (also can be disabled if you want to lock one ISO in)
- Vibration Capture mode which delays capture until the built in Seismograph shows no meaningful vibration
- Simple UI option which only displays Shutter/Aperture/ISO; for minimalists
- Excellent integration with technical cameras, where you'll find, by far, the best wide angle lenses made, and the option for rise/fall/shift on every lens, with no change in focal length or additional glass elements
- Industry leading dark-frame calibration for the cleanest long exposures (we've tested to 1-hour, but it should do fine much longer; we just don't have the patience to test several 2-hour exposures)
- Fastest and most feature-full wireless option (Capture Pilot)
- Dual battery power sharing, so when one starts to run low you can keep shooting without changing batteries, and when changing batteries the body/back both remain on using the other battery (no reboot of camera or reconnect to computer required).
- Strong legacy of good upgrade offers for upgrading to future backs
- Strong legacy of continued repair/service long after the product has been discontinued. LightPhase from 1998 is still supported in Capture One v9 in El Capitan; P20 (non plus) released in 2004 is still repairable and will be for several more years - compare this to the list of Hasselblad products which are no longer serviced.
- Professional support from expert dealers; for instance we (DT) have four full-time support people on staff covering three time zones, in addition to the four support people Phase One has at their US office. People usually default to thinking about "repairs" here, but the reality is 95% of our calls are about something other than a repair (questions about Capture One, needing help understanding a camera setting, a problem they are experiencing which they assume is a camera malfunction but is actually user error or a bad accessory like a bad 3rd party USB cable); getting someone on the phone who can straight away tell you the answer to an obscure question can come in handy!
And yes... as you say, Capture One support, which given how far of a lead Capture One 9 has now, is no small matter.
And the price difference is not as big as you think. There are four 50mp CMOS options from Team Phase One (Credo 50, IQ150, IQ250, IQ350) which covers a large range of potential budget (of course Hassy will only make the comparison to the flagship IQ350 when discussing pricing) and the list price is not the same as the street price from a good dealer. We're working with a client right now considering an IQ150 + XF + three Blue Ring lenses or an H5D-50C and we're getting him in the same range of pricing.
There are a few advantages to the H5D as well, such as the HTS system and True Focus (especially nice when shooting static subjects with wider lenses wide open with large recompositions). Some 20% or so of our new clients buying new bodies are going for H5X bodies with Phase One backs; but 80%+ are going for the XF. This is true at the lower price points (e.g. IQ150) as well as the higher price points (IQ380), so seems not to be purely a pricing issue.
*H1 released in 2002 is the basis for the H5. True focus and some increased focus speed being two of the only meaningful improvements since then. H1D released in 2004, the interface of which is still the basis of the H5D with incremental improvements.
**You can pick up from us same-day or have it couriered to you if in NYC or LA. Overnight delivery anywhere else in the country.
***Can be used with any brand of lighting, just add a Profoto Air Receiver to the light
****IQ series also has FW800 though in case you prefer it, for instance, because of the availability of 30' cables
